## ⚡ Quick start
<a id="why-retraining"></a>
## 💡 Why reTraining?
Deploying object detection models in industrial environments (manufacturing, logistics, agricultural feedmills, conveyor belts) often hits a painful bottleneck: **general base models fail on domain-specific edge cases, while building manual labeling pipelines from scratch is slow and expensive.**
**reTraining** provides a self-contained, enterprise-grade active learning platform designed to run directly on your edge server or GPU workstation:
1. **Ingest Raw CCTV Footage**: Stream directly from continuous 24/7 video archives without re-encoding or modifying the underlying storage.
2. **Zero-Shot Foundation Auto-Labeling**: Leverage Meta's Segment Anything Model 3 (**SAM3**) with natural language text prompts and visual exemplars to annotate thousands of frames in minutes.
3. **Roboflow-Grade Review Studio**: Sub-second keyboard navigation, instant class switching, click-assist segmentation, and high-density visual triage crop grids.
4. **Statistical Triage & Data Prep**: Filter bounding box outliers by area, aspect ratio, and confidence score without discarding valid image frames.
5. **Immutable Dataset Freezing & Stable Val Splits**: Guarantee reproducible benchmarks with deterministic SHA-1 validation sets that never shift across retraining runs.
6. **Hardware-Aware Continuous Fine-Tuning**: Auto-detect host GPU VRAM, fine-tune Ultralytics YOLO11 models, and evaluate base vs. fine-tuned model performance side-by-side.
7. **Live Production Counting & Benchmarks**: Real-time RTSP/WHEP live inference with ByteTrack line-crossing counters, evaluated against verified ground truth physical counts at **146 FPS**.

<a id="quickstart"></a>
## ⚡ Quickstart
### Prerequisites
- **Host OS**: Linux (Ubuntu 22.04+ recommended) or Windows with WSL2.
- **GPU Acceleration**: NVIDIA GPU with CUDA 12.4+ and [NVIDIA Container Toolkit](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html) (Docker Engine 27+ CDI support).
- **HuggingFace Account**: Gated model access granted for [facebook/sam3](https://huggingface.co/facebook/sam3) with a valid user access token (`HF_TOKEN`).
- **Video Storage**: Directory of CCTV footage structured as `<date>/<batch>.mp4` (or let the app mount `./data/archive`).
---
### Option 1: Docker Compose (Production Standard)
Launch the entire stack with a single command. The startup script automatically inspects the host hardware, generates Container Device Interface (CDI) specs for your NVIDIA GPU, and starts both backend and frontend containers.
```bash
cp .env.example .env # paste your HF_TOKEN
VIDEO_ARCHIVE_HOST=/path/to/videos docker compose up -d --build
# 1. Clone the repository
git clone git@github.com:fhanyuh/reTraining.git
cd reTraining
# 2. Configure environment credentials
cp .env.example .env
# Edit .env and paste your HuggingFace user access token:
# HF_TOKEN=hf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
# 3. Launch with automated GPU / CDI detection
chmod +x start.sh
./start.sh
```
Open **<http://localhost:8080>**. The API is on `:8000`.
*Alternative direct Docker Compose launch:*
```bash
curl localhost:8000/api/health
docker compose up -d --build
```
**Access Points**:
- 🌐 **Web Studio UI**: [http://localhost:8080](http://localhost:8080)
- 📑 **Interactive REST API Docs**: [http://localhost:8000/docs](http://localhost:8000/docs)
- 🩺 **Health & GPU Telemetry Endpoint**: [http://localhost:8000/api/health](http://localhost:8000/api/health)
Verify system health and GPU VRAM availability:
```bash
curl http://localhost:8000/api/health
```
```json
{ "device": "cuda", "gpu": "NVIDIA GeForce RTX 5080 Laptop GPU",
"vram_free_gb": 14.91, "sam3_ready": true, "ffmpeg": true,

<summary><b>What you need first</b></summary>
<br>
| Thing | Why |
|---|---|
| A GPU with the NVIDIA container toolkit | SAM3 is CUDA-only |
| A video archive laid out as `<date>/<batch>.mp4` | that structure is what the archive browser reads |
| `HF_TOKEN` with access to [facebook/sam3](https://huggingface.co/facebook/sam3) | the weights are gated, and approval is manual |
| A base model `.pt` (optional) | without one, training starts from `yolo11n.pt` and you type the classes yourself |
```

<details>
<summary><b>Run it without Docker (development)</b></summary>
<br>
```bash
uv pip install -r requirements.txt # backend
uv pip install -e sam3/
uv run uvicorn backend.main:app --reload # :8000
cd frontend && npm install
npm run dev # :5173, proxies /api to :8000
```
The frontend pins Vite 7 on purpose — Vite 8's Rolldown binding crashes on this machine.
The package manager is `uv`; there is no `pip`/`poetry` path.
</details>
> The initial SAM3 auto-annotation job automatically downloads the **~3.4 GB SAM3 checkpoint** from HuggingFace into a persistent Docker named volume (`hf-cache`). Subsequent executions load the model into VRAM in ~12 seconds.

## 🔄 How it works
### Option 2: Local Development (Bare-Metal / uv + Vite)
One project owns its base model, its class list, its video archive and its own accumulating
datasets. A second use case is a second project — not a second copy of the code.
For core development and live debugging without Docker:

I -.->|promote| H
**Requirements**: Python 3.12+, Astral [`uv`](https://docs.astral.sh/uv/), Node.js 20+, FFmpeg.
```bash
# 1. Clone and setup environment
git clone git@github.com:fhanyuh/reTraining.git
cd reTraining
cp .env.example .env
# 2. Install backend dependencies and vendored SAM3 with uv
uv pip install -r requirements.txt
uv pip install -e ./sam3
# 3. Start FastAPI backend (Port 8000)
uv run uvicorn backend.main:app --host 0.0.0.0 --port 8000 --reload
# 4. In a separate terminal, install and start Vite frontend (Port 5173)
cd frontend
npm install
npm run dev -- --host 0.0.0.0 --port 5173
```
> [!NOTE]
> **Data Prep is the gate.** Selecting batches does not create a dataset — it opens Data Prep
> scoped to that selection. Only *Confirm merge* cuts the dataset, and the filter rules in
> force at that moment are **frozen onto it**, so editing them later can never rewrite a
> dataset you already trained on.
> The frontend dependencies are pinned to **Vite 7** (`vite: ^7.1.5`) in `frontend/package.json` to prevent Rolldown native binding bus errors on Linux platforms.

## 🖥️ The screens
<a id="architecture"></a>
## 🏗️ End-to-End Pipeline Architecture
The platform operates as a continuous closed-loop retraining pipeline divided into 7 distinct functional stages:
```
┌──────────────────────────────────────────────────────────────────────────────────────────────────┐
│ DATA RETRAINING & INFERENCE PIPELINE │
└──────────────────────────────────────────────────────────────────────────────────────────────────┘
[1. Video Archive] ──▶ [2. Frame Slicing] ──▶ [3. SAM3 Auto-Label] ──▶ [4. Review & Exemplar]
(CCTV/MP4) (FFmpeg In/Out) (Prompt Grounding) (Click-Assist Canvas)
│
[7. Live Counter] ◀── [6. YOLO11 Train] ◀── [5. Immutable Split] ◀── [4. Triage & Filter]
(WHEP / RTSP) (Auto VRAM) (Stable Train/Val) (Outlier Purge)
```
1. **Video Archive & Shift Slicing**: Raw CCTV recordings are indexed into 24-hour operational work shifts (06:00 to 05:59 next morning). Sub-second timeline in/out trimming extracts high-resolution frame sequences with configurable FPS rates via asynchronous FFmpeg queues.
2. **SAM3 Foundation Auto-Labeling**: Meta SAM3 zero-shot open-vocabulary grounding generates candidate bounding boxes and segmentation masks from natural language descriptions (e.g. `"white sack of feed on conveyor"`).
3. **Interactive Review Studio**: Operators review candidate annotations on a Roboflow-grade canvas with single-keystroke approvals, box adjustments, click-assist segmentation, and visual prompt exemplar refinement.
4. **Statistical Triage & Quality Outliers**: Interactive 2D scatter plots (Box Area vs. Confidence Score) and high-density crop grids allow rapid isolation and pruning of false positives without discarding valid frames.
5. **Immutable Dataset Compilation**: Filtered batches are merged into versioned datasets (`v1`, `v2`, `v3`) with deterministic SHA-1 validation hashing, guaranteeing that validation images remain permanently locked across iterations.
6. **Hardware-Aware YOLO Retraining**: Hyperparameters and batch sizes auto-scale based on detected GPU VRAM. The system fine-tunes Ultralytics YOLO11, benchmarks old vs. new models on the identical validation set, and displays signed metric deltas ($\Delta\text{mAP50}$, $\Delta\text{Precision}$, $\Delta\text{Recall}$).
7. **Counting Accuracy Benchmark & Live Inference**: Real-time production inference evaluates live RTSP/WHEP video streams with ByteTrack trajectory tracking and upper-edge tripwire counters, benchmarking against hand-verified physical ground truth logs at **146 FPS**.

<details>
<summary><b>2. Video Archive</b> — browse by <i>cycle</i>, not by folder</summary>
<summary><b>1.2 24-Hour Operational Shift Archive</b> — Cycle grouping that crosses midnight</summary>
<br>
A **cycle** is one shift: `06:00 → 05:59` the next morning. It always crosses midnight, so it
always spans two calendar dates, and is named after the date it starts on.
<div align="center">
<img src="screenshots/03_library_video_archive.png" width="100%" alt="Video Archive Shift Cycle Browser" />
<p><i>Figure 1.3: Video Archive grouping recordings into 24-hour operational shifts (06:00 to 05:59 next morning).</i></p>
</div>
Folder names are not when a recording was made, and neither are file mtimes — those are file
*copy* times. The real start comes from the timestamp the camera burns into every frame, so a
file sitting in the `2026-08-14` folder but recorded at `00:11` shows up as part of the
**13 Aug** cycle, numbered in the order it was actually made.
```
Siklus 13 Agt 2026 28 rekaman
#1 08:27:27 batch003 2026-08-13
...
#25 23:53:45 batch027 2026-08-13
#26 00:11:02 batch001 2026-08-14 ← pulled in from the next folder
#27 00:34:01 batch002 2026-08-14
```
Nothing in the archive is moved or renamed — it is mounted **read-only**. The grouping lives
in an index beside it, and the original path stays the file's identity.
| Attribute | Specification |
|---|---|
| **🎯 Purpose** | Browse raw CCTV recordings grouped by operational work shifts rather than arbitrary calendar folders. |
| **⚡ Key Capabilities** | Reads camera burned-in OCR timestamps and sidecar `.json` metadata to assign recordings accurately across midnight boundaries. |
| **💡 Invariant** | The video archive is mounted **strictly read-only** (`:ro`). Nothing is ever modified, renamed, or deleted in the user's video repository. |

Approving no longer merges. It marks frames approved; merging happens in Data Prep.
| Attribute | Specification |
|---|---|
| **🎯 Purpose** | Fast, ergonomic manual review and refinement of auto-generated bounding boxes. |
| **⚡ Key Capabilities** | Single-key shortcuts, bottom thumbnail filmstrip with status indicators, and shape provenance tracking (`SAM3`, `Manual`, `Base Model`). |
| **💡 Invariant** | Approving frames does **not** merge them into a dataset. Approval merely qualifies frames for Data Prep; merging happens under frozen rules. |
</details>
<details>
<summary><b>5. Data Prep</b> — throw out the junk, then set augmentation</summary>
<summary><b>3.2 Visual Exemplar-Guided Prompting</b> — Few-shot visual reference matching</summary>
<br>
Tune an outlier filter over **score / area / aspect** against exactly the batches you picked,
watching the counts move as you drag. A dropped box leaves its image in the dataset; only a
frame that loses *every* box is held back — these frames hold ~44 objects each, and excluding
the whole image was measured to cost 96% of a batch to remove 10% of its boxes.
<div align="center">

<p><i>Figure 3.3: Exemplar Pool Sidebar Panel for visual reference matching.</i></p>
</div>
Then **Confirm merge** creates the dataset under a frozen copy of those rules.
</details>
<details>
<summary><b>6. Datasets</b> — several per project, each a standalone copy</summary>
<br>
`batch7+8 strict rules` and `batch7+8 after I fixed the annotations` are two datasets holding
the same frames with different labels. Combining them for a run is *newest wins*, so a frame
appearing twice is emitted once rather than teaching the model two contradictory labels.
</details>
<details>
<summary><b>7. Models & Training</b> — run, then read the comparison</summary>
<br>
Pick datasets, pick classes, train. Batch size, image size and device default from the
hardware actually detected, so a bigger GPU changes the numbers in the form, not the code.
</details>
<details>
<summary><b>8. Live Counting</b> — point a model at a camera and watch it count</summary>
<br>
Same tracker, stabiliser and line-cross counter the production script uses. Click the video to
place the counting line; it moves live without losing the counts. Every finished track is
written to a JSONL with the reason it did or did not count — which is what separates a model
miss from a tracker miss from a counter miss.
</details>
<details>
<summary><b>9. Counting Accuracy</b> — scored, per cycle</summary>
<br>
One row per recording, grouped into collapsible cycles. Type in the ground truth you counted
by hand and the table shows the **signed delta** — `+3` and `-3` are different failures, and a
single accuracy percentage hides which one you have. Totals only ever count rows where a
ground truth is filled in.
Recount runs headless in a background job — no annotated frame, no JPEG encode, which is worth
**146 fps vs 124** in the live view.
| Attribute | Specification |
|---|---|
| **🎯 Purpose** | Store and utilize positive and negative visual crop exemplars to guide SAM3 zero-shot grounding on difficult textures or ambiguous sack designs. |
| **⚡ Key Capabilities** | Visual exemplar library, similarity threshold slider, 1-click exemplar addition from canvas bounding boxes. |

### Phase 4: Data Prep, Statistical Triage & Dataset Freezing
The counter is deliberately robust to low frame rates: it never needs to catch the exact frame
of a crossing, only that a track was seen *above* the line at some point in its life.

| **⚡ Key Capabilities** | Dual-handle range sliders (Confidence Score, Box Area, Aspect Ratio), interactive SVG scatter plot, high-density crop grid cards, and real-time retention telemetry. |
| **💡 Invariant** | Dropping an outlier bounding box **leaves the frame in the dataset** unless all boxes are dropped. Industrial conveyor frames contain ~44 objects; dropping whole frames discards 96% of good data to remove 10% of bad boxes. |

<a id="counting-engine"></a>
## 🎥 Production Counting Engine
The counting engine is designed for industrial conveyor belts with low or unstable camera frame rates. It eliminates reliance on instantaneous line-crossing frames by evaluating historical bounding box trajectories.
```mermaid
stateDiagram-v2
[*] --> UNKNOWN
UNKNOWN --> ABOVE: y1 above the band
UNKNOWN --> BELOW: born below (ghost — never counts)
ABOVE --> COUNTED: seen below + travelled far enough
COUNTED --> ABOVE: sustained frames above (real unload)
UNKNOWN --> ABOVE: y1 coordinate above counting band
UNKNOWN --> BELOW: Born below band (ghost detection — rejected)
ABOVE --> COUNTED: Trajectory crosses band + travelled entry_travel_min
COUNTED --> ABOVE: Sustained frames above line (genuine reload)
```
<details>
<summary><b>Four layers, and what each one is actually for</b></summary>
### Multi-Layer Counter Safeguards
<br>
| Layer | Guard | Stops |
| Guard Layer | Rule Specification | Failure Mode Prevented |
|---|---|---|
| 1 | Must have been **above** the line at some point | a box that appears inside the truck |
| 2 | Must have travelled `entry_travel_min` from where it first appeared | ghost boxes that blink into existence next to the line |
| 3 | **Track hand-off** — a dying track parks its history for a newborn nearby to inherit | an ID switch at the line losing the count *or* duplicating it |
| 4 | One count per direction per track, and the verdict is the track's *last* direction | double counting, while still letting a genuine unload-and-reload count again |
Every one of these was written against a reproduced failure. Hand-off replaced a spatial dedup
that did not dedup: a blocked track simply retried each frame and counted anyway once it
drifted out of the circle — late, at the wrong position, seeding the next circle in the wrong
place.
`handoff_radius` is the dial that matters most. These frames hold ~44 objects, so a newborn
track is nearly always near one that just vanished; calibrate it against a clip with a
hand-counted total rather than by eye.
</details>
<details>
<summary><b>Recording pipeline</b> — record once, cut sessions afterwards</summary>
<br>
```mermaid
flowchart LR
CAM[📷 Dahua 1080p<br/>H.265 @ 25fps] --> MTX[MediaMTX on Jetson<br/>records 24/7 · 24h buffer]
MTX -->|RTSP| DET[Truck detector<br/>on the GPU box]
DET -->|session ends| FETCH[Download that exact<br/>time range as a copy]
MTX --> FETCH
FETCH --> ARC[📁 archive/date/batchNNN.mp4<br/>+ .json sidecar]
```
The detector does **not** encode video. When a truck session ends it downloads that range from
the recording server, so the archive keeps the camera's own codec, resolution and frame rate.
| | Before | After |
|---|---|---|
| Codec | mpeg4 re-encode | HEVC copy |
| Resolution | 1280×720 | 1920×1080 |
| Size | 8.0 Mbps | **1.72 Mbps** (4.7× smaller) |
| Timebase | declared 10 fps at 25 fps real → **2.49× slow** | true 25 fps |
| Start time | read from the burned-in overlay by OCR | from the server, exact |
Each clip carries a `.json` sidecar with the server's start time, which the app trusts over
reading the overlay — so a new session appears in the right cycle with no scan at all.
</details>
| **Layer 1: Entry Origin Guard** | Object must be observed **above** the counting band prior to crossing. | Prevents counting items that spawn directly inside the truck or loading chute. |
| **Layer 2: Trajectory Distance** | Object must travel a minimum distance (`entry_travel_min`) across consecutive frames. | Discards transient noise and flickering phantom boxes. |
| **Layer 3: Track Hand-Off** | When a track is occluded, its movement history is parked for newborn tracks within `handoff_radius`. | Prevents tracker ID switches from dropping or duplicating counts. |
| **Layer 4: Directional Monotonicity** | Strict single count per trajectory direction with verdict locked to the final confirmed motion. | Prevents double-counting during momentary conveyor pauses. |

## 📊 Why the numbers are trustworthy
<a id="configuration"></a>
## ⚙️ Configuration & Environment Matrix
After training, the base model and the new one are validated **on the same val set**, and
mAP50 / mAP50-95 / precision / recall appear side by side with the difference.
All configuration parameters are defined via environment variables in `.env`:
> [!TIP]
> **The val split is stable.** Once a frame is in `val` it stays there for every later merge —
> derived from the frame's identity, not from how many rows precede it. A rising score cannot
> be an easier val set.
- **Training uses whole datasets, old batches included.** Fine-tuning on the newest batch alone
tends to raise the score on new footage while quietly losing the old.
- **Datasets are snapshots.** Labels are copied from what the dataset holds on disk, not
re-derived from today's rules, so two runs over the same dataset cannot disagree.
- **An empty Base column is honest.** It means the previous model's classes did not match this
dataset's, so scoring it would have compared two different things. The message says which.
`Use as base model` promotes a version, and the next round fine-tunes from it.

## ⚙️ Background Job Worker & Mutex Locking
Heavy computational operations run through an asynchronous background worker (`backend/jobs.py`) with strict GPU mutex locking to prevent VRAM over-allocation:
| Job Type | GPU Locked | Description |
|---|:---:|---|
| `extract` | — | Background FFmpeg extraction of video ranges into frame sequences. |
| `autolabel` | ✅ | Meta SAM3 zero-shot grounding across candidate frames (one `set_image` per image). |
| `merge` | — | Compiles reviewed batches into immutable dataset splits under frozen triage rules. |
| `train` | ✅ | Ultralytics YOLO11 fine-tuning followed by automated dual-model validation. |
| `count` | ✅ | Headless evaluation benchmark running archive videos at **146 FPS**. |
| `clock-scan` | — | OCR extraction of camera burned-in timestamps. |
| `truck-scan` | ✅ | Batch inference check verifying the presence of target industrial objects. |
---
## ⚙️ Jobs
<a id="invariants"></a>
## 📊 Metrics Integrity & Domain Invariants
Heavy work runs as queued jobs, one at a time, so the GPU is never double-booked.
| Type | GPU | What it does |
|---|---|---|
| `extract` | — | ffmpeg pulls frames out of a range |
| `autolabel` | ✅ | SAM3 over a batch, one `set_image` per image |
| `merge` | — | copies approved frames into a dataset under frozen rules |
| `train` | ✅ | fine-tunes, then validates base and new on the same val set |
| `count` | ✅ | headless recount of archive videos for the accuracy table |
| `clock-scan` | — | reads each recording's real start time |
| `truck-scan` | ✅ | checks every recording actually contains a truck |
Jobs and their progress are persistent; after a restart the list is still there.
1. **Stable Validation Split**: Validation assignment is determined deterministically by `sha1(image_bytes) % 100 < val_ratio`. Once a frame lands in the validation split, it remains in validation across all future dataset iterations. This prevents validation leak and ensures that rising mAP scores reflect genuine model improvements.
2. **One `set_image` per Frame**: SAM3 executes its heavy vision transformer backbone once per image. Multi-class text prompting evaluates the lightweight grounding head against cached backbone embeddings.
3. **Outlier Filtering Preserves Frames**: Dropping a bounding box during Data Prep removes only the bad annotation. The image frame remains in the dataset as long as at least one valid box persists.
4. **Upper-Edge Coordinate Line Crossing ($y_1$)**: Tripwires evaluate the top edge coordinate of bounding boxes ($y_1$) rather than the centroid ($y_c$) or bottom edge ($y_2$), ensuring immunity to sack deformation upon conveyor impact.

| Symptom | Root Cause & Remediation |
|---|---|
| Videos listed as *unreadable* | ffprobe could not parse them; they are still listed rather than hidden, so the archive never looks emptier than it is |
| A recording's time shows amber | its overlay was read with low confidence, or not at all — type the time you can see in the video; a hand-entered time is never overwritten by a rescan |
| A cycle looks short | check whether its recordings moved to the neighbouring cycle — anything before 06:00 belongs to the previous shift |
| Live counting says *GPU busy* | a training or auto-label job holds the card; it waits 30 s before giving up |
| Video file marked as *unreadable* | FFmpeg/FFprobe could not parse the video header. Run `uv run python scripts/transcode_archive.py` to re-mux into standard H.264 MP4. |
| Shift cycle shows fewer recordings than expected | Check if recordings crossed the 06:00 boundary. Clips recorded before 06:00 belong to the previous operational shift cycle. |
| Live Counting shows *GPU busy* | An active fine-tuning or auto-annotation job holds the GPU lock. The live counter waits 30 seconds before falling back to CPU or queuing. |

## 🤝 Contributing & Engineering Guidelines
The documents drive the repo, not the other way round:
Development adheres strictly to the **Chain of Truth** methodology:
- **Specifications First**: Every feature must map directly to a numbered requirement in [`docs/requirements.md`](docs/requirements.md) and architectural design in [`docs/design.md`](docs/design.md).
- **Verified Deliverables**: Tasks tracked in [`docs/tasks.md`](docs/tasks.md) flip to `[DONE]` only after concrete end-to-end verification.
- **Surgical Changes**: Touch only code directly relevant to the feature. Adhere to the working rules in [`AGENTS.md`](AGENTS.md).
- **Package Manager**: All backend dependencies are managed exclusively with Astral `uv` (`requirements.txt`).
| Document | Contents |
|---|---|
| [`docs/requirements.md`](docs/requirements.md) | numbered `REQ-xxx`, changed only with the owner's approval |
| [`docs/design.md`](docs/design.md) | schema, API contract, disk layout — each section names the `REQ-xxx` it serves |
| [`docs/tasks.md`](docs/tasks.md) | implementation steps and how each was *verified*, `[TODO]` / `[DONE]` |
| [`AGENTS.md`](AGENTS.md) | working rules: simplicity, surgical changes, verify by running something |

Two invariants are easy to break and make the whole system lie:
<a id="license"></a>
## 📄 License
1. **A frame in `val` stays in `val`** — otherwise the base-vs-new comparison is meaningless.
2. **One `set_image` per image** — `set_text_prompt()` re-runs only the grounding head against
the cached backbone output. An N-prompt job calls `set_image` once and loops prompts over
that state.

# Bab 1: Ringkasan Sistem & Arsitektur Pipeline Data
Sistem retraining dan live counting karung pakan adalah platform vision berbasis deep learning terintegrasi untuk otomatisasi pelabelan, kurasi dataset, penyetelan halus (*fine-tuning*) model deteksi YOLO, serta verifikasi penghitungan objek karung pada konveyor transfer pabrik pakan ternak. Sistem dirancang guna menggantikan proses anotasi manual berulang serta memberikan jaminan stabilitas data latih antar-generasi model.
## 1.1 Latar Belakang & Tujuan Rekayasa
Operasional pabrik pakan menghadapi tantangan variasi visual konveyor: pergantian jenis karung (warna, corak, bahan laminasi), perubahan pencahayaan alami shift kerja, pergeseran sudut kamera CCTV, serta variasi kecepatan konveyor. Peningkatan akurasi model AI menuntut siklus retraining berkala yang cepat, terukur, dan tidak merusak performa deteksi sebelumnya.
Tujuan rekayasa platform:
1. **Otomatisasi Pelabelan Citra**: Memanfaatkan arsitektur Segment Anything Model 3 (Meta SAM3) berbasis prompt teks zero-shot untuk menghasilkan bounding box dan poligon instan.
2. **Jaminan Pembagian Data Valid**: Menerapkan algoritma *stable validation split* deterministik berbasis fungsi hash SHA-1 sehingga citra validasi tidak pernah bocor ke data latih.
3. **Penyetelan Halus Terkontrol**: Melatih arsitektur YOLO11 secara efisien dengan manajemen VRAM dinamis serta pembersihan direktori temporer otomatis.
4. **Verifikasi Penghitungan Nyata**: Menyediakan mesin pelacakan multi-lapisan (ByteTrack dan LineCrossCounter pada batas atas $y_1$) berkecepatan 146 FPS untuk memverifikasi akurasi terhadap data acuan kebenaran (*ground truth*).
## 1.2 Alur Pipeline 8 Tahap (8-Stage End-to-End Retraining Pipeline)
Alur pemrosesan data end-to-end terbagi menjadi 8 tahap berurutan:
```
[1. Video Archive / CCTV Ingest (06:00 Shift)]
│ (OCR Timestamp & Video Metadata)
▼
[2. Video Library & FFmpeg Frame Extractor]
│ (Range Streaming, Sampling at 1.0 FPS)
▼
[3. SAM3 Grounding Engine (Singleton CUDA)]
│ (Single set_image, Multi-Prompt Grounding, Exemplars)
▼
[4. Roboflow-Replica Review Canvas]
│ (Polygon Vertex/BBox Edit, Hotkeys, Source Tracking)
▼
[5. Data Prep, Outlier Triage & Augmentation]
│ (Score/Area/Aspect Keep-Ranges, Scatter Plot, Crop Grid)
▼
[6. Master Dataset Freezing & Stable Val Split]
│ (SHA1 Hash-based Val Split, Frozen Rules Snapshot, YOLO TXT)
▼
[7. YOLO Retraining & Model Comparison Benchmark]
│ (VRAM Auto-Tuning, Fine-Tuning, Base vs New mAP Comparison)
▼
[8. Live Inference Counter & Headless Accuracy Benchmark]
│ (ByteTrack, LineCrossCounter on y1, WebRTC/WHEP, GT Benchmark)
```

## 1.3 Peran Komponen Arsitektur Utama
Sistem terdiri dari enam komponen komputasi independen:
1. **Frontend Web Studio (Port 8080 / 5173)**: Antarmuka Single Page Application (SPA) berbasis React 19 dan Vite 7. Mengimplementasikan kanvas review berlatar gelap, visualisasi scatter plot SVG interaktif, tabel benchmark delta akurasi, dan panel kontrol live video WebRTC.
2. **Backend Application Server (Port 8000)**: Server REST API asinkron berbasis FastAPI dan Uvicorn (Python 3.12). Menangani streaming video HTTP 206, orkestrasi antrean pekerjaan, parser OCR, manipulasi dataset, dan interfacing model.
3. **GPU Singleton Engine Manager**: Modul resident CUDA yang mengelola model SAM3 (~3.9 GB VRAM dasar) dan proses training YOLO secara mutual eksklusif menggunakan mekanisme `jobs.gpu_lock` (timeout 20 detik).
4. **MediaMTX Streaming Server (Port 8554 & 8889)**: Gateway video multi-protokol yang menerima feed RTSP H.264/H.265 dari kamera Dahua CCTV (:8554) dan mentransmisikan ulang melalui protokol WebRTC WHEP berlatensi rendah (:8889) langsung ke peramban.
5. **Algoritma Tracking & Line Crossing**: Mesin pelacakan ByteTrack dipadukan dengan logika tripwire `LineCrossCounter` yang membaca tepi atas karung ($y_1$) untuk mencegah manipulasi perhitungan akibat deformasi fisik karung.
6. **SQLite WAL Database & Filesystem Storage**: Database SQLite (`data/app.db`) dalam mode Write-Ahead Logging (WAL) untuk persistensi metadata relasional, dipadukan dengan direktori file terstruktur untuk penyimpanan citra mentah, label teks YOLO, dan file bobot `.pt`.
## 1.4 Prinsip Desain: Hardware Agnosticism, Portabilitas & Pencegahan Drift
1. **Agnostisisme Perangkat Keras**: Sistem tidak mematok konfigurasi GPU tertentu pada kode sumber statis. File inisialisasi `start.sh` mendeteksi ketersediaan NVIDIA Container Device Interface (CDI) secara dinamis dan menginjeksi parameter ke `docker-compose.override.yml`. Jika GPU tidak terdeteksi, sistem beralih otomatis ke mode fallback CPU tanpa mengalami crash.
2. **Portabilitas Lingkungan**: Menggunakan manajer paket `uv` dan lockfile deterministik untuk Python, serta Nginx reverse proxy yang menyamakan jalur routing `/api/` antara kontainer Docker dan server pengembangan lokal.
3. **Pencegahan Konfigurasi Drift**: Seluruh konfigurasi sensitif (seperti `HF_TOKEN`) dibaca eksklusif dari file `.env`. Jalur direktori internal selalu menggunakan relasi path relatif terhadap basis data aplikasi.
# Bab 2: Panduan Setup, Instalasi & Eksekusi Lingkungan Kerja
Bab ini memuat instruksi operasional untuk menjalankan sistem pada dua mode eksekusi: kontainer produksi Docker (dengan akselerasi GPU) dan lingkungan pengembangan lokal (*local development*).
## 2.1 Prasyarat Sistem & Dependensi Perangkat Keras
Konfigurasi perangkat keras dan dependensi minimum:
- **Prosesor (CPU)**: x86_64 Quad-Core 2.5 GHz atau lebih tinggi.
- **Memori Utama (RAM)**: Minimum 16 GB DDR4 (direkomendasikan 32 GB untuk caching dataset besar).
- **Akselerator Grafis (GPU)**: NVIDIA GPU dengan VRAM minimum 8 GB (arsitektur Turing, Ampere, Ada Lovelace, atau Blackwell) dan driver NVIDIA versi 535+.
- **Penyimpanan**: NVMe SSD dengan ruang kosong minimum 100 GB.
- **Sistem Operasi Host**: Ubuntu Linux 22.04 LTS atau 24.04 LTS.
- **Perangkat Lunak**: Docker Engine 27.0+, Docker Compose v2.20+, NVIDIA Container Toolkit, Git, FFmpeg, curl.
## 2.2 Metode Eksekusi 1: Docker Compose dengan Akselerasi GPU (Produksi)
Docker Compose adalah metode standar pada deployment server industri.
Langkah 1: Kloning repositori dan persiapkan berkas konfigurasi lingkungan:
```bash
cd /home/asus/feedmill/reTraining
cp .env.example .env
```
Langkah 2: Konfigurasikan token Hugging Face dan jalur arsip video pada `.env`:
```ini
HF_TOKEN=hf_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
VIDEO_ARCHIVE_HOST=/home/asus/feedmill/data/archive
WEB_PORT=8080
```
Langkah 3: Jalankan skrip inisialisasi otomatis:
```bash
./start.sh
```
Skrip `start.sh` akan memverifikasi keberadaan `docker`, memeriksa ketersediaan GPU via `nvidia-smi`, menghasilkan konfigurasi override CDI, membangun citra kontainer backend dan frontend, lalu mengaktifkan layanan pada latar belakang (*detached mode*).
Langkah 4: Verifikasi status kontainer:
```bash
docker compose ps
```
Hasil verifikasi yang valid menunjukkan dua kontainer berstatus `Up`:
- `retraining-backend-1` (Port 8000)
- `retraining-frontend-1` (Port 8080)
## 2.3 Metode Eksekusi 2: Pengembangan Lokal (uv & npm)
Mode pengembangan lokal digunakan saat pengujian kode sumber secara cepat tanpa proses build image Docker.
Langkah 1: Instal dependensi Python backend menggunakan `uv`:
```bash
# Pastikan uv telah terpasang pada host
curl -LsSf https://astral.sh/uv/install.sh | sh
# Instal seluruh dependensi backend
uv pip install -r requirements.txt
```
Langkah 2: Instal dependensi Node.js frontend:
```bash
cd frontend
npm install
cd ..
```
Langkah 3: Jalankan backend FastAPI (Terminal 1):
```bash
uv run uvicorn backend.main:app --host 0.0.0.0 --port 8000 --reload
```
Langkah 4: Jalankan frontend Vite dev server (Terminal 2):
```bash
npm --prefix frontend run dev -- --host 0.0.0.0
```
Aplikasi web lokal dapat diakses melalui peramban pada alamat `http://localhost:5173`.
## 2.4 Konfigurasi File .env & Manajemen Kredensial
File `.env` terletak pada direktori akar repositori dan tidak boleh diikutsertakan ke dalam version control publik.
Tabel parameter konfigurasi `.env`:
| Nama Variabel | Nilai Default / Contoh | Tipe | Deskripsi Operasional |
|---|---|---|---|
| `HF_TOKEN` | `hf_AbCdEf...` | String | Token otentikasi Hugging Face untuk mengunduh bobot Meta SAM3. |
| `VIDEO_ARCHIVE_HOST` | `/home/asus/feedmill/data/archive` | Path | Jalur direktori arsip video CCTV pada host machine. |
| `WEB_PORT` | `8080` | Integer | Port Nginx frontend yang diekspos ke jaringan lokal host. |
| `BACKEND_PORT` | `8000` | Integer | Port FastAPI backend service. |
| `RTSP_URL` | `rtsp://192.168.192.96:8554/cam` | URL | URL stream RTSP kamera conveyor dari MediaMTX. |
| `WHEP_URL` | `http://192.168.192.96:8889/cam/whep` | URL | Endpoint WebRTC WHEP untuk pemutaran video langsung di UI. |
## 2.5 Pemeriksaan Kesehatan Sistem (Health Check)
Untuk menguji kesiapan layanan backend, jalankan perintah curl berikut:
```bash
curl -s http://localhost:8000/api/health | jq .
```
Respons JSON yang valid:
```json
{
"status": "ok",
"gpu_available": true,
"device": "cuda:0",
"sam3_loaded": false,
"active_jobs": 0
}
```
# Bab 3: Manajemen Proyek & Taksonomi Kelas
Bab ini memandu operator dalam menginisialisasi proyek baru, menetapkan geometri anotasi, menyusun taksonomi kelas deteksi, serta memetakan teks prompt untuk model segmentasi otomatis.
## 3.1 Struktur Proyek & Ruang Kerja Terisolasi
Setiap proyek deteksi merepresentasikan satu target fisik spesifik pada lini produksi (misalnya deteksi karung pakan ayam 50kg, karung pakan ikan, atau palet konveyor). Seluruh aset citra, file anotasi, subset validasi, dan versi model tersimpan secara terisolasi di dalam direktori `data/projects/<slug>/`.
![Antarmuka Manajemen Proyek](screenshots/01_projects_page.png)
*Gambar 1: Antarmuka Manajemen Proyek (Projects Overview).* Menampilkan kartu ringkasan proyek aktif, model dasar YOLO primer dan sekunder, taksonomi kelas dengan kuantitas objek terdeteksi, statistik pembagian data latih/validasi, serta tombol navigasi modul.
*(English label: Projects Overview Page)*
## 3.2 Pembuatan Proyek Baru & Parameter Awal
Untuk membuat proyek baru, klik tombol `+ New project` pada bagian atas halaman Projects. Sistem akan membuka form modal pembuatan proyek.
![Form Pembuatan Proyek Baru](screenshots/02_project_create_modal.png)
*Gambar 2: Form Pembuatan Proyek Baru (New Project Modal).* Konfigurasi nama proyek, jenis geometri anotasi (BBox atau Polygon), rasio langkah pembagian validasi (*val split stride*), jalur arsip video, dan penetapan prompt teks SAM3 awal untuk setiap kelas.
*(English label: Project Creation Modal)*
Parameter pada form pembuatan proyek:
1. **Project Name**: Nama identifikasi proyek (misalnya `Feedmill Sack Counter`). Nama ini akan diubah menjadi format URL slug (contoh `feedmill-sack-counter`).
2. **Label Type (Geometri)**:
- `bbox` (Bounding Box): Format koordinat segi empat $[x_{\text{min}}, y_{\text{min}}, x_{\text{max}}, y_{\text{max}}]$. Direkomendasikan untuk deteksi objek reguler dan kecepatan inferensi maksimal.
- `polygon`: Format koordinat poligon segmentasi multi-titik $[(x_1, y_1), (x_2, y_2), \dots]$. Direkomendasikan untuk objek saling tumpang tindih (*heavy occlusion*).
*Perhatian: Jenis geometri terkunci permanen setelah batch pertama digabungkan ke dataset.*
3. **Val Split (Langkah Validasi)**: Nilai integer $N$ (default $5$). Menentukan bahwa setiap citra ke-$N$ secara konsisten dialokasikan sebagai data validasi (rasio $1/N = 20\%$).
4. **Video Archive Root**: Jalur direktori arsip video CCTV (default `/videos`).
5. **Model Checkpoint**: Opsi untuk mengunggah bobot awal `.pt` (misalnya `v4-best.pt`). Jika disediakan, sistem secara otomatis mengekstrak nama kelas dari metadata bobot (`model.names`).
## 3.3 Taksonomi Kelas & Pemetaan Prompt Teks
Tabel definisi kelas dan pemetaan prompt pada proyek deteksi karung pakan:
| ID Kelas | Nama Kelas | Warna Swatch | Prompt Teks SAM3 | Deskripsi Objek Fisik |
|---|---|---|---|---|
| `0` | `sack` | `#3b82f6` (Biru) | `white woven plastic sack on conveyor belt` | Karung pakan plastik tenun putih yang melintas di konveyor. |
| `1` | `sack_damaged` | `#ef4444` (Merah) | `torn damaged sack leaking feed powder` | Karung sobek, bocor, atau kemasan rusak parah. |
| `2` | `person` | `#10b981` (Hijau) | `worker operator person handling bags` | Operator atau pekerja pabrik di sekitar konveyor. |
Peraturan kaskade perubahan kelas:
- Penambahan kelas baru memperbarui entri tabel `project_classes` dan menambahkan kunci kelas pada `data.yaml`.
- Penghapusan kelas memicu pembersihan seluruh anotasi kelas tersebut pada database dan disk, serta melakukan re-indeks penomoran ID kelas yang lebih tinggi untuk mencegah celah indeks (*gap index*).
- Penghapusan kelas terakhir pada proyek diblokir oleh sistem untuk menjaga integritas skema.
# Bab 4: Pengelolaan Video Archive & Siklus Kerja 24 Jam
Bab ini menguraikan mekanisme pengorganisasian arsip rekaman CCTV, konversi stempel waktu video melalui Optical Character Recognition (OCR), dan pemindaian otomatis keberadaan truk pengangkut.
## 4.1 Logika Siklus Kerja 24 Jam (Shift 06:00)
Pabrik pakan ternak menerapkan siklus kerja 24 jam yang dimulai pukul 06:00 pagi dan berakhir pukul 05:59 pagi pada hari berikutnya. Sistem mengelompokkan rekaman video berdasarkan siklus kerja operasional pabrik, bukan berdasarkan tanggal kalender standar tengah malam (00:00).
Formula penetapan tanggal siklus kerja ($D_{\text{siklus}}$):
$$D_{\text{siklus}} = \begin{cases} D_{\text{kalender}}, & \text{jika } t_{\text{rekam}} \ge 06:00:00 \\ D_{\text{kalender}} - 1 \text{ hari}, & \text{jika } t_{\text{rekam}} < 06:00:00 \end{cases}$$
Contoh: Video yang direkam pada tanggal 14 Agustus 2026 pukul 02:30:00 dini hari akan dikelompokkan ke dalam **Siklus 13 Agu 2026**.
![Video Archive & Siklus Produksi](screenshots/03_library_video_archive.png)
*Gambar 3: Video Archive & Siklus Produksi 24 Jam (Library Page).* Panel siklus kerja harian pada sisi kiri, indikator validasi OCR (lingkaran amber untuk jam belum terverifikasi), status deteksi truk v4, rincian resolusi/durasi video, dan tombol aksi pemotongan.
*(English label: Video Archive & Cycles Tree)*
## 4.2 Ekstraksi Jam Video melalui OCR & Koreksi Manual
Kamera CCTV industri melakukan pembakaran stempel waktu (*burned-in timestamp*) langsung pada piksel video pojok kanan atas atau kiri bawah. Modul `backend/video_clock.py` mengekstrak koordinat waktu tersebut menggunakan metode pencocokan template (*template matching*) 12 glif angka (0 sampai 9, `:`, dan spasi).
Prosedur penanganan stempel waktu:
1. Sistem membaca frame pertama video dan melakukan crop area koordinat jam.
2. Hasil OCR disimpan pada tabel `video_clock` sebagai teks waktu lokal (*wall-clock time* format `HH:MM:SS`) untuk menghindari pergeseran akibat konversi zona waktu UTC/WIB di peramban.
3. Apabila skor kecocokan glif OCR berada di bawah ambang batas ($<0.85$), baris siklus ditandai dengan ikon lingkaran amber (perlu verifikasi).
4. Operator dapat mengklik teks waktu pada antarmuka dan mengetikkan koreksi jam secara manual.
## 4.3 Pemindaian Truk Massal Terotomatisasi (Truck Scan v4)
Tidak semua video arsip memuat aktivitas bongkar muat karung. Untuk menghemat waktu anotasi, sistem menyediakan fitur pemindaian truk menggunakan model `v4-best.pt`.
Langkah operasional:
1. Buka halaman Library proyek (`/projects/<id>`).
2. Klik tombol `Cek truk (v4)` pada header tabel arsip.
3. Server mengeksekusi inferensi berkecepatan tinggi pada sampel frame video terpilih (1 frame per 10 detik).
4. Kolom `Truk` pada tabel akan menampilkan rasio keberadaan truk:
- **Badge Hijau (contoh `12/12`)**: Truk terdeteksi konsisten, video siap dipotong dan dianotasi.
- **Badge Merah (`tanpa truk`)**: Konveyor dalam keadaan kosong/mati, video dapat dilewati.
- **Badge Abu-abu (`belum dicek`)**: Video baru yang belum dipindai.
# Bab 5: Pemotongan Video & Ekstraksi Frame
Bab ini menjelaskan teknik isolasi segmen rekaman video operasional dan ekstraksi frame citra beresolusi penuh untuk persiapan dataset pelatihan.
## 5.1 Editor Pemotongan Video (Trim Page)
Modul pemotongan video memanfaatkan protokol HTTP 206 (*Partial Content Range Streaming*) pada backend FastAPI (`/projects/{id}/video?rel=...`). Protokol ini memungkinkan peramban melakukan scrubbing timeline video secara instan tanpa mengunduh keseluruhan berkas video berukuran gigabyte.
![Editor Pemotongan Video](screenshots/04_trim_page.png)
*Gambar 4: Editor Pemotongan Video & Ekstraksi Frame (Trim Page).* Pemutar video HTML5 dengan slider rentang waktu In/Out, tombol sinkronisasi playhead, input laju sampling FPS, badge estimasi total frame, dan tombol eksekusi ekstraksi.
*(English label: Video Trim & Frame Extractor)*
## 5.2 Penentuan Rentang Timecode & Sampling FPS
Langkah operasional pemotongan video:
1. Geser playhead video ke titik awal saat karung pertama mulai bergerak di atas konveyor.
2. Klik tombol `Use playhead` pada slider **Start** untuk mengunci waktu In.
3. Geser playhead ke titik akhir saat karung terakhir melintasi garis konveyor.
4. Klik tombol `Use playhead` pada slider **End** untuk mengunci waktu Out.
5. Tentukan nilai **Frames per second (FPS)**:
- **Nilai Standar (1.0 FPS)**: Mengekstrak 1 frame per detik. Pilihan optimal untuk konveyor berkecepatan normal (0.3 sampai 0.6 m/s) guna menghindari duplikasi visual yang berlebihan.
- **Nilai Tinggi (2.0 FPS)**: Digunakan pada konveyor cepat atau kondisi karung bertumpuk rapat.
- **Nilai Rendah (0.5 FPS)**: Digunakan untuk perekaman durasi panjang dengan variasi visual minimal.
6. Periksa badge kalkulasi otomatis: `<durasi detik> of video -> <N> frame(s)`.
7. Klik tombol `Extract frames`.
## 5.3 Manajemen Antrean Batch Hasil Ekstraksi
Setelah tombol `Extract frames` ditekan, backend mendaftarkan pekerjaan ke antrean `jobs` dan mengeksekusi perintah FFmpeg secara asinkron:
```bash
ffmpeg -ss <start_sec> -to <end_sec> -i <video_path> -vf fps=<fps> -q:v 2 frames/%06d.jpg
```
Frame citra disimpan dengan format penomoran enam digit (`000001.jpg`, `000002.jpg`, dst.) di dalam direktori `data/projects/<slug>/batches/<batch-id>/frames/`.
![Tabel Manajemen Batch](screenshots/05_batches_page.png)
*Gambar 5: Tabel Manajemen Batch (Batches Page).* Daftar batch hasil ekstraksi, informasi rentang timecode dan FPS, total frame, rasio review visual, kuantitas deteksi, serta tombol eksekusi auto-labeling dan penggabungan dataset.
*(English label: Batch Work Queue Table)*
Aksi operasional pada tabel batch:
- **Checkbox Seleksi**: Memilih satu atau beberapa batch untuk proses penggabungan (*merge*).
- **Auto-annotate**: Membuka dialog pelabelan otomatis SAM3 untuk batch tunggal.
- **Review (n/N)**: Masuk ke modul kanvas review anotasi interaktif.
- **Reset Auto**: Menghapus seluruh anotasi otomatis (`source='auto'`) dan mempertahankan anotasi manual (`source='manual'`).
- **Download Annotations (.zip)**: Mengunduh arsip ZIP berisi citra dan file label teks YOLO.
- **Restore from .zip**: Memulihkan anotasi dari berkas cadangan ZIP eksternal.
# Bab 6: Pelabelan Otomatis Menggunakan SAM3 Grounding Engine
Bab ini menguraikan arsitektur model segmentasi Meta SAM3, mekanisme pelabelan otomatis berbasis prompt teks zero-shot, panduan interaksi kotak contoh (*exemplar*), serta penggunaan modul Playground.
## 6.1 Arsitektur SAM3 Zero-Shot Grounding
Meta Segment Anything Model 3 (SAM3) adalah arsitektur *vision foundation model* dengan kemampuan melokalisasi dan mengelompokkan objek citra secara zero-shot berdasarkan deskripsi bahasa alami (*open-vocabulary grounding*).
Arsitektur inferensi SAM3 diimplementasikan melalui modul `backend/sam3_engine.py`:
- Model memuat bobot Vision Transformer (ViT) dasar dengan konsumsi VRAM awal ~3.9 GB.
- **Eksekusi Tunggal `set_image()`**: Tulang punggung fitur visual (*vision backbone*) memproses citra frame hanya satu kali dan menyimpan representasi fitur (*backbone_out*) pada cache memori GPU.
- **Evaluasi Multi-Prompt**: Kepala penyelaras teks (*grounding head*) dieksekusi berulang kali pada representasi fitur yang sama untuk setiap kelas prompt tanpa mengulang komputasi backbone.
## 6.2 Auto-Labeling Batch Tunggal & Exemplar Tuning
Untuk menjalankan pelabelan otomatis pada batch tertentu, klik tombol `Auto-annotate` pada baris batch.
![Modal Auto-Anotasi SAM3 Tunggal](screenshots/06_batches_sam3_auto_annotate_modal.png)
*Gambar 6: Modal Auto-Anotasi SAM3 Tunggal (Auto-Annotate Modal).* Kanvas preview deteksi interaktif, slider ambang batas confidence, NMS IoU, filter ukuran minimum kotak, serta bidang gambar kotak exemplar positif dan negatif.
*(English label: Single-Batch SAM3 Modal)*
Parameter konfigurasi auto-labeling:
1. **Confidence Threshold (0.05 sampai 0.95, default 0.35)**: Skor probabilitas minimum deteksi. Naikkan nilai jika muncul deteksi palsu (*false positive*) pada latar belakang konveyor; turunkan nilai jika karung buram tidak terdeteksi.
2. **NMS IoU Threshold (0.0 sampai 0.9, default 0.0)**: Ambang batas Non-Maximum Suppression untuk mengeliminasi kotak tumpang tindih dari prompt berbeda (*cross-prompt NMS*). Nilai 0.0 mengaktifkan pembersihan tumpang tindih ketat.
3. **Min Box Size Fraction (0 sampai 50%, default 0%)**: Mengabaikan deteksi objek dengan luas area di bawah persentase tertentu terhadap total luas frame. Berguna untuk memfilter serpihan kecil atau noise debu.
4. **Interactive Exemplar Prompting**:
- **Kotak Positif (`+1`)**: Klik dan tarik (*drag*) kursor mouse pada objek karung yang tidak terdeteksi. SAM3 akan memprioritaskan fitur visual objek serupa.
- **Kotak Negatif (`-2`)**: Tekan tombol `Shift` + tarik kursor mouse pada objek non-target (misalnya kaki operator atau refleksi lantai). SAM3 akan mengabaikan pola visual tersebut.
5. Klik tombol `Run Preview` untuk mengevaluasi hasil penyesuaian parameter sebelum menyimpan ke database.
## 6.3 Auto-Labeling Massal Multi-Batch
Apabila operator memiliki puluhan batch rekaman yang baru diekstraksi, gunakan fitur auto-labeling massal.
![Modal Auto-Anotasi Massal](screenshots/07_batches_mass_auto_annotate_modal.png)
*Gambar 7: Modal Auto-Anotasi Massal (Mass Auto-Annotate Modal).* Pilihan engine pelabelan (SAM3 Zero-Shot, Base Model v4, atau Model Kustom), daftar centang batch target, dan tombol eksekusi antrean sekuensial.
*(English label: Mass Auto-Annotation Modal)*
Opsi engine pelabelan:
- **SAM3 Zero-Shot**: Menggunakan Meta SAM3 dengan prompt teks proyek. Sangat fleksibel untuk objek baru.
- **Project Base Model**: Menggunakan model YOLO proyek yang sedang aktif (misalnya `v4-best.pt`). Kecepatan inferensi jauh lebih tinggi dibandingkan SAM3.
- **Custom YOLO Model**: Menggunakan file checkpoint `.pt` khusus yang diunggah operator.
Seluruh proses massal dieksekusi secara sekuensial oleh worker backend di bawah proteksi `jobs.gpu_lock` untuk mencegah benturan VRAM.
## 6.4 SAM3 Global Playground
Modul Playground (`/sam3-playground`) menyediakan lingkungan uji coba terisolasi untuk menguji efektivitas prompt teks tanpa memengaruhi database proyek aktif.
![SAM3 Global Playground](screenshots/20_sam3_playground_page.png)
*Gambar 8: SAM3 Global Playground.* Area unggah gambar bebas, kotak input multi-prompt teks dipisahkan tanda koma, kanvas visualisasi hasil segmentasi instan, dan pembacaan waktu komputasi GPU.
*(English label: SAM3 Prompt Playground)*
Panduan penggunaan Playground:
1. Tarik (*drag-and-drop*) berkas gambar JPEG/PNG ke dalam area dropzone.
2. Ketik prompt teks deskriptif pada kolom input (contoh: `white plastic sack, forklift, worker`).
3. Klik tombol `Run SAM3`.
4. Evaluasi ketepatan kontur segmentasi dan skor confidence yang dihasilkan.
# Bab 7: Kanvas Review & Anotasi Interaktif
Bab ini menguraikan fitur penyuntingan anotasi pada kanvas berlatar gelap, sistem koordinat ternormalisasi, navigasi tombol pintas keyboard, dan aturan kardinal anotasi objek konveyor.
## 7.1 Tata Letak Kanvas Gelap Roboflow-Replica
Modul Review (`/projects/{id}/review?batch=<batch_id>`) dirancang untuk kenyamanan mata operator selama sesi verifikasi panjang. Seluruh koordinat geometri disimpan dalam format mengambang ternormalisasi $0.0$ sampai $1.0$ terhadap dimensi lebar dan tinggi frame asli.
Format koordinat ternormalisasi:
$$x_{\text{norm}} = \frac{x_{\text{piksel}}}{W_{\text{frame}}}, \quad y_{\text{norm}} = \frac{y_{\text{piksel}}}{H_{\text{frame}}}$$
![Kanvas Review & Anotasi Interaktif](screenshots/08_review_annotation_canvas.png)
*Gambar 9: Kanvas Review & Anotasi Interaktif (Review Page).* Kanvas anotasi dengan bounding box dan kontur poligon, filmstrip status frame di sisi bawah, sidebar daftar kelas dan bentuk objek, serta panel navigasi tombol pintas.
*(English label: Canvas Review & Annotation)*
## 7.2 Prosedur Review Cepat Menggunakan Hotkeys
Antarmuka review mendukung kendali penuh berbasis keyboard (*keyboard-first workflow*):
Tabel daftar tombol pintas (Hotkeys):
| Tombol Pintas | Fungsi Operasional | Efek pada Sistem |
|---|---|---|
| `A` | **Approve Frame** | Menandai frame saat ini sebagai `approved` (hijau) dan otomatis berpindah ke frame berikutnya. |
| `X` | **Reject Frame** | Menandai frame saat ini sebagai `rejected` (merah) dan berpindah ke frame berikutnya. |
| `<-` / `->` | **Navigasi Frame** | Berpindah mundur atau maju satu frame pada timeline batch. |
| `N` | **Next Annotated** | Melompat langsung ke frame berikutnya yang memiliki objek anotasi. |
| `C` | **Copy Previous** | Menyalin seluruh anotasi dari frame sebelumnya ke frame aktif saat ini. |
| `Del` / `Backspace` | **Delete Shape** | Menghapus kotak atau poligon yang sedang aktif/terpilih. |
| `V` | **Toggle Tool** | Beralih mode antara kursor seleksi (*Select*) dan mode menggambar (*Draw*). |
| `1` sampai `9` | **Fast Reclass** | Mengubah kelas objek yang dipilih secara instan sesuai nomor urut kelas. |
| `Esc` | **Cancel / Deselect** | Membatalkan seleksi bentuk aktif atau menutup overlay dialog. |
## 7.3 Penyuntingan Vertex Poligon & Bounding Box
Manipulasi bentuk pada kanvas:
- **Bounding Box**: Klik objek untuk memunculkan 8 titik handle tepi. Tarik handle sudut untuk mengubah skala, atau tarik badan kotak untuk menggeser posisi.
- **Poligon Segmentasi**: Klik poligon untuk memunculkan titik-titik vertex bulat (`.handle-vertex`) dan titik tengah tepi (`.handle-midpoint`).
- Tarik `.handle-vertex` untuk memindahkan sudut kontur.
- Klik `.handle-midpoint` untuk menyisipkan titik sudut baru pada kontur poligon.
- Tekan tombol `Alt` + klik pada titik vertex untuk menghapus titik tersebut (jumlah titik minimum poligon adalah 3).
## 7.4 Quick Reclass Bar & Filmstrip Navigasi
Pada bagian atas kanvas review, bilah *Quick Reclass Bar* menyediakan akses satu klik untuk mengganti klasifikasi objek.
![Quick Reclass Bar & Filmstrip](screenshots/09_review_filmstrip_quick_reclass.png)
*Gambar 10: Quick Reclass Bar & Filmstrip Navigasi.* Bilah penggantian kelas cepat dengan badge warna dan tombol hapus bentuk, dipadukan dengan filmstrip thumbnail frame di bagian bawah kanvas.
*(English label: Quick Reclass & Filmstrip)*
Status frame pada filmstrip:
- **Garis Tepi Hijau**: Frame berstatus disetujui (*approved*), siap digabungkan ke dataset master.
- **Garis Tepi Merah**: Frame berstatus ditolak (*rejected*), akan dilewati saat proses merge.
- **Garis Tepi Kuning/Abu-abu**: Frame berstatus tunda (*pending*), belum diperiksa oleh operator.
## 7.5 Panel Filter Exemplar In-Review
Operator dapat menyetel ulang deteksi SAM3 secara lokal langsung dari sidebar review tanpa perlu kembali ke halaman batch.
![Panel Filter Exemplar Interaktif](screenshots/12_review_exemplar_pool_panel.png)
*Gambar 11: Panel Filter Exemplar Interaktif (Exemplar Filter Panel).* Panel sidebar untuk mengatur ambang batas confidence, NMS overlap, batas ukuran minimum, dan kuantitas deteksi maksimum secara real-time.
*(English label: In-Review Exemplar Filter Panel)*
## 7.6 Kebijakan Anotasi Kardinal: Penanganan Oklusi Garis Atas (y1)
Sistem penghitungan live counting mengandalkan pemicu tepi atas kotak karung ($y_1$). Oleh karena itu, operator wajib mematuhi aturan kardinal anotasi:
1. **Aturan Oklusi Tepi Atas**: Apabila tepi atas karung terhalang oleh kepala pekerja, tangan operator, atau karung lain yang menumpuk di atasnya, **jangan buat anotasi pada karung tersebut**. Membiarkan kotak deteksi dengan $y_1$ yang salah akan menyebabkan pemicuan ganda (*double triggering*) pada algoritma counting.
2. **Karung Terpotong Tepi Bawah**: Karung yang hanya terlihat sebagian pada bagian bawah namun memiliki tepi atas yang jelas **wajib dianotasi** hingga batas visual yang tampak.
3. **Pewarisan Anotasi Manual**: Setiap modifikasi manual yang dilakukan operator pada kanvas review akan mengubah status sumber anotasi menjadi `source='manual'`. Anotasi manual terlindungi dan tidak akan tertimpa jika fungsi auto-annotation dijalankan ulang.
# Bab 8: Penyiapan Data, Triage Kualitas & Augmentasi
Bab ini membahas modul Data Prep sebagai gerbang kendali mutu (*quality gate*) sebelum data digabungkan ke dataset master, visualisasi scatter plot logaritmik, galeri crop grid, dan konfigurasi augmentasi sintetis.
## 8.1 Filter Pencilan (Outlier Triage Filter) Non-Destruktif
Modul Outlier Filter (`backend/triage.py`) melakukan evaluasi otomatis pada seluruh anotasi di dalam batch terpilih berdasarkan tiga metrik geometris tanpa menghapus data secara permanen (*non-destructive filtering*).
![Filter Outlier Kualitas Data](screenshots/13_data_prep_quality_outliers.png)
*Gambar 12: Filter Outlier Kualitas Data (Data Prep Outliers).* Tiga kartu filter keep-range untuk confidence score, persentase luas area kotak, dan aspect ratio, dilengkapi ringkasan kuantitas objek lolos/terfilter.
*(English label: Outlier Quality Filter)*
Tiga metrik penapisan outlier:
1. **Confidence Score (0.00 sampai 1.00)**: Menyingkirkan deteksi otomatis dengan tingkat keyakinan rendah yang berpotensi merupakan false positive.
2. **Box Area % (0.00% sampai 100.00%)**: Menyingkirkan objek yang terlalu kecil (noise debu konveyor) atau terlalu besar (artefak background yang mencakup seluruh layar).
3. **Aspect Ratio W/H (0.00 sampai 10.00)**: Menyingkirkan kotak deteksi yang terlalu pipih atau terlalu ramping vertikal yang tidak sesuai dengan proporsi fisik karung pakan standar.
Prinsip kerja triage rules:
- Anotasi yang berada di luar rentang batas (*keep-range*) ditandai sebagai `ignored`.
- Anotasi manual (`source='manual'`) memiliki preseden tertinggi dan **selalu dipertahankan** meskipun nilainya berada di luar batas filter.
- Frame yang kehilangan 100% anotasi akibat filter outlier akan ditahan (*held back*) dan tidak dimasukkan ke dalam dataset master untuk mencegah pencemaran citra latar belakang kosong yang tidak disengaja.
## 8.2 Konfigurasi Augmentasi Citra
Augmentasi data menghasilkan variasi citra sintetis untuk meningkatkan generalisasi model terhadap perubahan kondisi pabrik.
![Panel Konfigurasi Augmentasi](screenshots/14_data_prep_augmentation_panel.png)
*Gambar 13: Panel Konfigurasi Augmentasi Gambar (Augmentation Panel).* Pemilihan preset augmentasi (Off, Light, Medium, Aggressive) dan 9 slider penyesuaian parameter geometri serta fotometri.
*(English label: Augmentation Preset Panel)*
Tabel preset dan parameter augmentasi:
| Parameter | Preset Light | Preset Medium (Default) | Preset Aggressive | Deskripsi Transformasi |
|---|---|---|---|---|
| `fliplr` | 0.5 | 0.5 | 0.5 | Probabilitas pembalikan horizontal citra (kiri ke kanan). |
| `flipud` | 0.0 | 0.0 | 0.2 | Probabilitas pembalikan vertikal citra (atas ke bawah). |
| `degrees` | 0.0° | 5.0° | 15.0° | Rentang rotasi acak derajat kemiringan. |
| `translate` | 0.05 | 0.10 | 0.20 | Translasi pergeseran posisi gambar secara acak. |
| `scale` | 0.10 | 0.20 | 0.50 | Skala pembesaran/pengecilan objek acak. |
| `hsv_h` | 0.01 | 0.015 | 0.03 | Variasi spektrum hue warna citra. |
| `hsv_s` | 0.3 | 0.5 | 0.7 | Variasi saturasi warna citra. |
| `hsv_v` | 0.2 | 0.3 | 0.5 | Variasi kecerahan/kegelapan (*value*) pencahayaan. |
| `mosaic` | 0.0 | 0.5 | 1.0 | Probabilitas penggabungan 4 potongan citra menjadi satu. |
*Invarian penting: Seluruh parameter augmentasi hanya diterapkan pada subset data latih (train). Subset data validasi (val) tidak pernah diaugmentasi agar evaluasi benchmark tetap murni.*
## 8.3 Analisis Sebaran Logaritmik & Marquee Selection
Scatter plot interaktif (`TriageScatter.jsx`) menyajikan visualisasi sebaran seluruh anotasi dalam grafik dua dimensi: Sumbu Y mewakili Confidence Score (0.0 sampai 1.0) dan Sumbu X mewakili Luas Area Kotak dalam skala logaritmik ($10^{-3}$ hingga $10^0$).
![Scatter Plot Triage Score vs Area](screenshots/11_review_triage_scatter_plot.png)
*Gambar 14: Scatter Plot Triage Score vs Area Logaritmik.* Titik-titik anotasi objek dengan garis batas penapisan merah putus-putus, seleksi area kotak (marquee tool), dan bilah penetapan keputusan manual (*verdict bar*).
*(English label: Triage Scatter Plot Log Scale)*
Fitur interaktif Scatter Plot:
- Garis putus-putus merah menandai batas keep-range aktif.
- Operator dapat mengklik dan menarik kursor untuk membuat kotak seleksi (*marquee selection*) pada sekumpulan titik anomali.
- Tombol aksi pada *Verdict Bar*:
- `Keep`: Menetapkan override manual agar objek terpilih selalu diikutsertakan.
- `Ignore`: Menetapkan override manual agar objek terpilih selalu dibuang.
- `Clear hand decisions`: Menghapus keputusan override manual.
## 8.4 Inspeksi Kualitas Melalui Crop Grid
Galeri Crop Grid (`TriageCropGrid.jsx`) menampilkan potongan thumbnail piksel dari setiap anotasi yang diurutkan dari skor terendah atau ukuran terkecil.
![Grid Crop Triage Objek](screenshots/10_review_triage_crop_grid.png)
*Gambar 15: Grid Crop Triage Objek (Triage Crop Grid).* Galeri 120 thumbnail potongan objek resolusi server, garis tepi berwarna penanda status, informasi skor dan persentase area, serta seleksi massal.
*(English label: Triage Crop Grid Inspection)*
Fitur Crop Grid:
- Mengambil potongan gambar langsung dari backend secara cepat (`/api/projects/{id}/crop-grid`).
- Garis tepi hijau menunjukkan objek lolos filter, garis tepi abu-abu/merah menunjukkan objek terfilter.
- Operator dapat memilih beberapa thumbnail dan menerapkan keputusan `Keep` atau `Ignore` secara instan.
## 8.5 Modal Konfirmasi Penggabungan Dataset
Setelah operator memastikan parameter filter dan augmentasi telah optimal, klik tombol `Prepare & Merge Selected`.
![Modal Konfirmasi Merge Dataset](screenshots/15_data_prep_merge_target_modal.png)
*Gambar 16: Modal Konfirmasi Merge Dataset (Merge Target Modal).* Opsi target dataset (memperbarui dataset aktif atau membuat dataset baru), peringatan batch yang belum direview penuh, dan tombol konfirmasi penggabungan.
*(English label: Dataset Merge Target Modal)*
Logika penggabungan (*merge gate*):
- Jika terdapat batch yang belum berstatus 100% reviewed, sistem menampilkan kotak peringatan kuning. Operator wajib mencentang opsi persetujuan `Merge them unreviewed` untuk melanjutkan.
- Saat konfirmasi diberikan, sistem mengambil snapshot aturan triage aktif dan menyimpannya ke kolom `datasets.rules_json`.
# Bab 9: Manajemen Dataset Master & Pembagian Validasi Permanen
Bab ini membahas struktur dataset master, mekanisme pembekuan data (*dataset freezing*), invarian pembagian validasi stabil berbasis hash kriptografis, dan integrasi dataset eksternal.
## 9.1 Mekanisme Pembekuan Dataset (Dataset Freezing)
Dataset master adalah kumpulan citra dan label teks terverifikasi yang siap digunakan untuk melatih model. Setiap operasi penggabungan (*merge*) bersifat atomik: citra frame disalin ke direktori `data/projects/<slug>/datasets/<id>/images/`, label YOLO diekspor ke `labels/`, dan konfigurasi `data.yaml` dihasilkan secara otomatis.
![Halaman Manajemen Dataset Master](screenshots/16_datasets_page.png)
*Gambar 17: Halaman Manajemen Dataset Master (Datasets Page).* Ringkasan dataset master, jumlah total citra, rasio pembagian data latih/validasi, riwayat versi aturan triage, dan bilah kalkulasi gabungan multi-dataset.
*(English label: Master Datasets & Split View)*
## 9.2 Invarian: Pembagian Validasi Stabil (Stable Validation Split)
Salah satu kesalahan fatal dalam sistem machine learning industri adalah pergeseran data validasi antar waktu (*data leakage / unstable split*). Apabila sebuah frame citra berada pada set validasi pada model v1, lalu berpindah ke set pelatihan pada model v2, maka perbandingan metrik mAP antar kedua model tersebut menjadi tidak valid.
Untuk menjamin stabilitas absolut, sistem mengimplementasikan algoritma hashing pada `backend/dataset.py:split_for()`:
```python
import hashlib
def split_for(project_id: int, batch_id: int, frame_stem: str, val_every: int = 5) -> str:
# Membentuk string identifikasi unik konten frame
key = f"{project_id}:{batch_id}:{frame_stem}".encode("utf-8")
hash_digest = hashlib.sha1(key).hexdigest()
# Mengonversi 8 karakter pertama hash ke integer
hash_int = int(hash_digest[:8], 16)
# Menentukan alokasi split secara deterministik
if hash_int % val_every == 0:
return "val"
return "train"
```
Karakteristik Pembagian Validasi Stabil:
1. **Deterministik Murni**: Penentuan status `train` atau `val` sepenuhnya ditentukan oleh nama file, ID batch, dan ID proyek.
2. **Kekebalan Mutasi**: Meskipun batch baru ditambahkan atau batch lama dihapus, frame yang pernah masuk ke subset `val` akan selalu tetap berada di subset `val` pada setiap dataset baru yang dibuat.
3. **Penyusunan File Disk**: Citra langsung disalin ke folder terpisah:
- `images/train/<batch-id>__<frame_idx>.jpg`
- `images/val/<batch-id>__<frame_idx>.jpg`
## 9.3 Integrasi Base Datasets Eksternal (Train-Only)
Sistem mendukung integrasi dataset luar (*base datasets*) melalui tabel `base_datasets`. Dataset eksternal ini umumnya berisi ribuan foto karung pakan dari pabrik lain atau domain publik.
Aturan isolasi base dataset:
- Seluruh citra dari base dataset dimasukkan **eksklusif ke subset data latih (`train`)**.
- Citra base dataset tidak pernah diizinkan masuk ke subset validasi (`val`) untuk memastikan benchmark akurasi proyek murni mencerminkan performa pada kamera lini produksi lokal.
## 9.4 Operasi Resync, Kombinasi Multi-Dataset & Ekspor ZIP
Aksi pada kartu dataset:
- **Resync Rules**: Menerapkan ulang aturan triage terbaru ke dataset yang telah ada. *Perhatian: Operasi ini bersifat destruktif terhadap snapshot aturan sebelumnya dan hanya boleh dilakukan jika terjadi pembaruan kebijakan mutu data.*
- **Combine Preview Strip**: Centang lebih dari satu kotak dataset pada halaman Datasets. Bilah atas akan menampilkan kalkulasi instan: `N selected · T unique images · X train / Y val`. Saat pelatihan model dijalankan, sistem menggabungkan dataset-dataset tersebut secara virtual tanpa duplikasi file.
- **Download (.zip)**: Mengunduh arsip dataset lengkap berstruktur standar YOLO (folder `images`, `labels`, dan `data.yaml`) untuk keperluan pelatihan eksternal.
# Bab 10: Pelatihan Model YOLO & Evaluasi Benchmark
Bab ini memandu prosedur penyetelan halus (*fine-tuning*) bobot YOLO11, pemantauan log pelatihan real-time, evaluasi komparatif metrik mAP, serta promosi bobot model terbaik.
## 10.1 Konfigurasi Pelatihan Model
Pelatihan model dilakukan melalui antarmuka Models (`/projects/{id}/models`).
![Halaman Konfigurasi Training & Evaluasi](screenshots/17_models_training_page.png)
*Gambar 18: Halaman Konfigurasi Training & Evaluasi Model (Models Page).* Panel konfigurasi parameter epoch, probe perangkat keras otomatis, pemilihan kombinasi dataset, serta tabel perbandingan metrik evaluasi model terhadap base model.
*(English label: YOLO Model Training & Metrics)*
Langkah konfigurasi pelatihan:
1. **Pilih Base Model Weights**: Pilih checkpoint dasar (misalnya `v4-best.pt` atau bobot pretrained Ultralytics `yolo11n.pt` / `yolo11n-seg.pt`).
2. **Target Classes**: Pilih kelas deteksi yang akan dilatih.
3. **Epochs**: Masukkan jumlah siklus pelatihan (default 50 epoch, rekomendasi 30 sampai 100 epoch untuk fine-tuning).
4. **Hardware Auto-Probe**: Sistem memeriksa kapasitas VRAM GPU host secara otomatis:
- VRAM < 8 GB: `batch=8, imgsz=640`
- VRAM 8 sampai 16 GB: `batch=16, imgsz=640`
- VRAM > 16 GB: `batch=32, imgsz=768`
- CPU Fallback: `batch=4, imgsz=512`
5. **Pilih Dataset Pelatihan**: Centang dataset master dan base dataset yang akan dilibatkan dalam pelatihan.
6. Klik tombol `Start Training`.
## 10.2 Manajemen Memori GPU & Eksekusi Training
Saat tombol pelatihan diklik:
1. Backend mengakuisisi kunci eksklusif GPU (`jobs.gpu_lock`).
2. Jika engine SAM3 sedang aktif di VRAM, sistem secara otomatis mengeksekusi `sam3_engine.release_engine()`, memanggil `torch.cuda.empty_cache()`, dan membersihkan memori agar 100% kapasitas VRAM dapat digunakan oleh proses pelatihan YOLO.
3. Skrip pelatihan `backend/training.py` mengeksekusi library Ultralytics dengan parameter optimal:
- Optimizer: `AdamW` atau `SGD` (otomatis)
- Cache mode: RAM caching jika RAM host > 16 GB, atau disk caching jika RAM terbatas.
- Workers: 4 thread loader.
## 10.3 Monitoring Progres Pelatihan Real-Time
Selama pelatihan berlangsung, antarmuka web menampilkan kartu pekerjaan aktif dengan terminal log interaktif.
![Monitoring Progres Pelatihan Real-Time](screenshots/21_workflow_progress_states.png)
*Gambar 19: Status Monitoring Progres Pelatihan Real-Time.* Indikator progres epoch aktif, utilisasi VRAM, kurva penurunan box_loss, cls_loss, dfl_loss, estimasi sisa waktu (ETA), dan tombol pembatalan pekerjaan.
*(English label: Active Training Job & Logs)*
Informasi pada terminal log:
- Nilai kerugian box loss (`box_loss`), class loss (`cls_loss`), dan distribution focal loss (`dfl_loss`).
- Metrik presisi dan recall per epoch.
- Tombol `Cancel`: Mengirimkan sinyal terminasi ke worker pelatihan dan membersihkan direktori sementara `runs/`.
## 10.4 Evaluasi Komparatif Like-for-Like
Setelah proses pelatihan selesai, modul `backend/evaluate.py` secara otomatis mengevaluasi performa model baru (`best.pt`) dan membandingkannya secara langsung (*like-for-like*) dengan model dasar (*base model*) menggunakan subset validasi yang identik (`data.yaml`).
Tabel metrik evaluasi model:
| Versi Model | Status | mAP50 | mAP50-95 | Precision | Recall | Signed Delta $\Delta$ mAP50 | Status Keputusan |
|---|---|---|---|---|---|---|---|
| `v1` | Arsip | 0.884 | 0.612 | 0.891 | 0.875 | Basis Awal | Model Awal |
| `v2` | Arsip | 0.912 | 0.654 | 0.920 | 0.898 | `+0.028` (Hijau) | Ditingkatkan |
| `v3` | Arsip | 0.938 | 0.701 | 0.942 | 0.925 | `+0.026` (Hijau) | Ditingkatkan |
| `v4` | **Base Aktif** | 0.965 | 0.748 | 0.968 | 0.952 | `+0.027` (Hijau) | **Standar Produksi** |
| `v5` | Kandidat | 0.978 | 0.772 | 0.981 | 0.969 | `+0.013` (Hijau) | Siap Dipromosikan |
Penjelasan nilai Delta $\Delta$:
- **Nilai Positif Hijau (`+0.013`)**: Menandakan model baru memiliki akurasi deteksi lebih unggul pada data validasi.
- **Nilai Negatif Merah (`-0.015`)**: Menandakan terjadi penurunan performa (*model regression*); model baru sebaiknya tidak dipromosikan.
## 10.5 Promosi Model Baru (Model Promotion)
Jika model kandidat (misalnya `v5`) terbukti menghasilkan delta mAP positif dan lolos pengujian:
1. Klik tombol `Use as base model` pada baris model tersebut.
2. Sistem secara atomik menyalin file bobot `data/projects/<slug>/models/5/best.pt` ke jalur model dasar proyek `data/projects/<slug>/base/model.pt`.
3. Model baru langsung aktif sebagai rujukan utama untuk modul pemindaian truk, auto-labeling, dan mesin live counting.
# Bab 11: Sistem Live Counting & Integrasi Kamera CCTV
Bab ini menguraikan arsitektur penanganan aliran video kamera, kalibrasi posisi garis pemicu hitung (*tripwire*), algoritma pelacakan ByteTrack, dan penyetelan parameter histeresis.
## 11.1 Topologi Streaming MediaMTX
Kamera industri Dahua IPC-HFW1230 mengirimkan stream RTSP beresolusi 1080p / 704x576 pada 25 FPS ke server MediaMTX.
Topologi distribusi video:
```
[Kamera CCTV Dahua] ──(RTSP H.264/H.265)──> [MediaMTX Server :8554]
│
┌───────────────────────────────────────────┴───────────────────────────────────────────┐
▼ (WHEP WebRTC Port :8889) ▼ (RTSP Local Port :8554)
[Browser UI: Live Video Panel] [Backend: YOLO + ByteTrack :8000]
(Zero-copy, Ultra Low Latency <200ms) (High-throughput Inference ~100 FPS)
```
Perbedaan fungsi kedua jalur:
1. **Jalur Browser (WHEP WebRTC)**: Ditransmisikan langsung dari MediaMTX ke elemen `<video>` peramban untuk monitoring operator dengan latensi ultra rendah tanpa membebani CPU backend.
2. **Jalur Inferensi Backend (RTSP)**: Dibaca oleh OpenCV backend untuk proses deteksi objek, pelacakan trajectory, dan kalkulasi garis hitung.
![Antarmuka Live Counting & Kalibrasi](screenshots/19_live_count_page.png)
*Gambar 20: Antarmuka Live Counting & Kalibrasi Tripwire (Live Count).* Tampilan visual stream kamera, penempatan garis hitung interaktif di kanvas, slider parameter pelacakan, dan ubin statistik perhitungan real-time.
*(English label: Live Inference & Tripwire Panel)*
## 11.2 Penempatan Garis Hitung Interaktif & Kalibrasi Tripwire
Pada antarmuka Live Count (`/projects/{id}/live-count`), operator dapat mengkalibrasi garis tripwire secara visual langsung di atas kanvas video:
- Klik chip `Counting line` lalu klik posisi vertikal konveyor pada video untuk mengatur nilai `line_y` (koordinat normalisasi $0.0$ sampai $1.0$).
- Klik chip `Left edge` lalu klik batas kiri konveyor untuk mengatur nilai `line_x_start`.
- Klik chip `Right edge` lalu klik batas kanan konveyor untuk mengatur nilai `line_x_end`.
- Seluruh perubahan koordinat garis disimpan langsung ke database dan diterapkan secara instan ke mesin hitung (`/api/live-count/line`).
## 11.3 Algoritma Pelacakan ByteTrack & LineCrossCounter pada y1
Mesin pelacakan objek (`algoritma-batch/src/tracker.py` dan `counting.py`) mengombinasikan dua lapisan algoritma:
1. **ByteTrack Multi-Object Tracker**: Mengasosiasikan kotak deteksi antar frame menggunakan matriks kemiripan IoU dan Kalman Filter. ByteTrack mempertahankan ID objek meskipun karung mengalami oklusi sementara dengan parameter `track_buffer: 60` (mampu mengingat lintasan objek hingga 60 frame atau 2.4 detik).
2. **LineCrossCounter Triggering pada $y_1$**:
- Pemicu perhitungan didasarkan secara eksklusif pada **koordinat tepi atas kotak ($y_1$)**.
- Arah pergerakan dihitung dari perpindahan vektor lintasan: jika $y_1$ bergerak dari atas garis ($y_1 < \text{line\_y}$) melewati garis menuju ke bawah ($y_1 \ge \text{line\_y}$), sistem mencatat peristiwa **Count In**.
- Sebaliknya, perpindahan dari bawah ke atas dicatat sebagai **Count Out**.
## 11.4 Penanganan Histeresis Lintasan & Parameter Tracking
Tabel parameter pelacakan live counting:
| Parameter | Rentang Nilai | Default | Deskripsi Fungsi |
|---|---|---|---|
| `line_y` | 0.10 sampai 0.90 | 0.50 | Posisi koordinat vertikal garis hitung tripwire pada frame. |
| `margin` | 10 sampai 100 px | 30 px | Lebar zona toleransi histeresis di sekitar garis hitung. |
| `entry_travel_min` | 10 sampai 200 px | 40 px | Jarak perpindahan minimum yang wajib ditempuh objek sebelum diizinkan memicu hitungan. Mencegah false trigger dari noise getaran konveyor. |
| `handoff_radius` | 20 sampai 250 px | 100 px | Radius pencarian serah-terima lintasan (*track handoff*). Jika ID objek terputus akibat oklusi mendadak, objek baru dalam radius ini mewarisi riwayat lintasan ID lama. |
| `unload_confirm_frames` | 1 sampai 30 frame | 5 frame | Jumlah frame konfirmasi sebelum status bongkar dikunci. |
| `min_area_scale` | 0.001 sampai 0.10 | 0.008 | Ambang batas fraksi luas area minimum objek yang diakui. |
| `conf` | 0.10 sampai 0.90 | 0.35 | Ambang batas confidence deteksi YOLO pada stream video. |
*Eliminasi Deteksi Semu (Ghost Box)*: Objek baru yang tiba-tiba terdeteksi pertama kali tepat di bawah garis hitung tanpa memiliki riwayat lintasan di atas garis diklasifikasikan sebagai *ghost detection* dan diabaikan oleh sistem.
# Bab 12: Benchmark Akurasi Perhitungan Headless
Bab ini membahas modul evaluasi akurasi perhitungan berkecepatan tinggi tanpa antarmuka grafis (*headless counting bench*), integrasi data acuan kebenaran (*ground truth*), dan diagnosa kesalahan hitung.
## 12.1 Eksekusi Rekalkulasi Video Batch Headless (~146 FPS)
Modul Counting Bench (`/projects/{id}/counting-bench`) dirancang untuk memvalidasi akurasi model pada ratusan berkas video arsip secara cepat. Dengan menonaktifkan rendering antarmuka dan enkripsi transmisi WebSocket, pemrosesan video pada GPU dapat mencapai kecepatan **146 hingga 220 FPS** (dibandingkan mode live stream visual yang dibatasi pada 25 FPS).

## 12.2 Impor Data Acuan Kebenaran (Ground Truth) dari Excel
Data acuan kebenaran (*ground truth*) adalah angka riil hasil penghitungan manual oleh petugas tally pabrik.
Metode pengisian Ground Truth:
1. **Impor Berkas Excel (`docs/GT.xlsx`)**: Sistem membaca berkas spreadsheet yang memuat kolom tanggal, nomor batch, dan kuantitas karung fisik, lalu memetakan nilainya ke tabel `count_runs` database secara otomatis.
2. **Koreksi Manual Langsung di Tabel**: Operator dapat mengklik kotak input angka pada kolom `Ground Truth` di antarmuka Counting Bench dan mengisikan angka hitungan fisik secara manual.
## 12.3 Evaluasi Metrik Signed Delta Error & Akurasi
Perhitungan selisih kesalahan dihitung menggunakan formula *Signed Delta Error* ($\Delta$):
$$\Delta = \text{Counted}_{\text{AI}} - \text{Ground Truth}$$
Kategori status pada tabel benchmark:
- **Tanda Nol (`0`) Hijau**: Hitungan model AI persis sama dengan data fisik riil (Akurasi 100%).
- **Tanda Positif (`+N`) Kuning/Oranye**: Terjadi penghitungan berlebih (*overcounting*) sebanyak $N$ karung.
- **Tanda Negatif (`-N`) Merah**: Terjadi penghitungan kurang (*undercounting*) sebanyak $N$ karung.
Formula Akurasi Total Siklus:
$$\text{Akurasi (\%)} = \left(1 - \frac{\sum |\text{Counted}_{\text{AI}} - \text{Ground Truth}|}{\sum \text{Ground Truth}}\right) \times 100\%$$
*Perhatian: Kalkulasi total akurasi hanya dihitung pada baris video yang telah memiliki nilai Ground Truth non-kosong.*
## 12.4 Diagnosa & Mitigasi Kesalahan Hitung
Panduan mitigasi deviasi hitungan:
Tabel diagnosa masalah counting:
| Gejala Masalah | Penyebab Teknis Utama | Solusi Penanganan Rekayasa |
|---|---|---|
| **Penghitungan Berlebih (+Delta)** | 1. Karung memantul di atas garis tripwire sehingga memicu garis dua kali.<br>2. ID track terputus lalu muncul ID baru tepat di garis.<br>3. Pekerja berdiri di area garis hitung. | 1. Perlebar nilai parameter `margin` (misal dari 30px ke 50px).<br>2. Naikkan nilai `handoff_radius` (misal dari 100px ke 150px).<br>3. Sesuaikan batas koordinat horizontal `line_x_start` dan `line_x_end` agar tidak mencakup area berdiri operator. |
| **Penghitungan Kurang (-Delta)** | 1. Dua karung bertumpuk rapat dihitung sebagai satu objek (oklusi).<br>2. Kecepatan konveyor terlalu tinggi sehingga objek melompati garis toleransi dalam 1 frame.<br>3. Confidence model terlalu tinggi pada karung kusam. | 1. Tambahkan data latih karung tumpuk dan latih ulang model.<br>2. Turunkan nilai `entry_travel_min` atau posisikan garis hitung di area konveyor yang lebih stabil.<br>3. Turunkan threshold `conf` dari 0.35 ke 0.25 pada pengaturan Live Count. |

# Bab 14: Invarian Domain, Penanganan Kasus Batas & Pemecahan Masalah
Bab penutup ini merangkum invarian domain yang tidak boleh dilanggar, panduan penanganan skenario kasus batas (*edge cases*), dan tabel pemecahan masalah teknis (*troubleshooting*).
## 14.1 Invarian Domain Tak Tergoyahkan (Core System Invariants)
Tiga invarian utama yang menjamin kebenaran ilmiah dan stabilitas sistem:
1. **Invarian 1: Pembagian Validasi Stabil (Stable Validation Split)**
*Prinsip*: Sekali sebuah frame citra dialokasikan ke dalam subset validasi (`val`), frame tersebut **wajib tetap berada di subset validasi selamanya** pada seluruh dataset masa depan.
*Rasional*: Mencegah kontaminasi data validasi ke data latih yang dapat menyebabkan nilai metrik mAP menjadi overoptimis dan tidak valid.
2. **Invarian 2: Eksekusi Tunggal `set_image()` per Frame pada SAM3**
*Prinsip*: Metode `Sam3Processor.set_image()` hanya dipanggil **satu kali per citra**. Pengujian multi-prompt dijalankan melalui pemanggilan berulang `set_text_prompt()` pada state fitur yang sama.
*Rasional*: Menghindari komputasi ulang Vision Transformer yang memboroskan siklus GPU dan memperlambat auto-labeling hingga 5 kali lipat.
3. **Invarian 3: Pemicuan Tripwire Berbasis Tepi Atas ($y_1$)**
*Prinsip*: Garis hitung tripwire hanya merespons lintasan koordinat puncak objek ($y_1$).
*Rasional*: Mencegah distorsi hitungan akibat perubahan panjang kantong karung saat tertekan di konveyor.
## 14.2 Penanganan Kasus Batas (Edge Cases)
Panduan sistem saat menghadapi skenario operasional khusus:
- **Kasus 1: Frame Tanpa Objek (Negative Sample Frame)**
Jika sebuah citra frame tidak memuat karung sama sekali (konveyor kosong), proses ekspor dataset tetap menghasilkan file label `.txt` kosong (ukuran 0 byte). File label kosong ini sangat penting bagi model YOLO untuk mempelajari representasi latar belakang (*background learning*) dan menekan false positive.
- **Kasus 2: Oklusi Parsial oleh Pekerja**
Jika karung tertutup sebagian oleh badan operator namun tepi atas ($y_1$) tetap terlihat jelas, buat anotasi hanya pada batas visual karung yang tampak. Jangan menebak bentuk di balik tubuh pekerja.
- **Kasus 3: Benturan Akses GPU Secara Bersamaan**
Jika pengguna memicu pelatihan model saat proses auto-labeling batch sedang berjalan, antrean tugas backend akan menahan perintah pelatihan dengan status `pending` hingga auto-labeling selesai atau dibatalkan oleh operator.
- **Kasus 4: URL RTSP Dimasukkan pada Form Live Count Web**
Peramban web standar tidak mendukung pemutaran langsung protokol RTSP. Jika operator memasukkan URL berawalan `rtsp://`, antarmuka akan menampilkan pesan kesalahan informatif dan memandu operator untuk memasukkan endpoint WebRTC WHEP MediaMTX (`http://...:8889/.../whep`).
## 14.3 Matriks Solusi Pemecahan Masalah (Troubleshooting Matrix)
Daftar masalah umum dan langkah penanganan cepat:
| Gejala Masalah | Indikasi Log / Error Code | Penyebab Akar | Tindakan Perbaikan |
|---|---|---|---|
| **Kegagalan Auto-Labeling SAM3** | `HTTP 401 Unauthorized` atau `HF ValidationError` | Token Hugging Face pada berkas `.env` belum diisi atau tidak memiliki izin akses ke repositori Meta SAM3. | Buka Hugging Face, buat User Access Token bertipe Read, setujui lisensi SAM3 di portal Meta, lalu perbarui variabel `HF_TOKEN` pada file `.env`. |
| **CUDA Out of Memory (OOM)** | `torch.cuda.OutOfMemoryError: CUDA out of memory` | Alokasi VRAM melampaui kapasitas fisik GPU saat training atau auto-labeling. | 1. Turunkan parameter ukuran batch (`batch=8` atau `batch=4`).<br>2. Turunkan resolusi citra latih (`imgsz=640` atau `512`).<br>3. Pastikan tidak ada proses Python zombie yang mengunci VRAM dengan menjalankan `fuser -v /dev/nvidia*`. |
| **Streaming WebRTC Gelap / Putus** | `WHEP connection failed (ICE timeout)` | MediaMTX belum menerima feed RTSP dari kamera atau koneksi jaringan VPN terputus. | 1. Uji koneksi ping ke IP kamera Dahua (`ping 192.168.192.96`).<br>2. Buka dashboard MediaMTX dan verifikasi bahwa stream `/cam` berstatus aktif.<br>3. Restart layanan MediaMTX. |
| **Video Scrubbing Lambat / Macet** | `HTTP 200 OK` (Bukan HTTP 206) | Nginx atau peramban tidak mendukung byte range request atau file video mengalami korupsi index moov atom. | 1. Jalankan perintah `qt-faststart` atau `ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4` untuk memindahkan metadata moov atom ke awal berkas.<br>2. Pastikan header `Accept-Ranges: bytes` aktif pada Nginx. |
| **Perbedaan Hitungan Signifikan pada Benchmark** | Delta bertanda merah besar (`-50` atau `+70`) | Posisi garis tripwire bergeser atau resolusi video berubah pasca pemeliharaan kamera. | 1. Buka halaman Live Count dan lakukan kalibrasi ulang garis `line_y`, `line_x_start`, dan `line_x_end`.<br>2. Periksa stempel waktu OCR pada Counting Bench untuk memastikan tidak ada batch rekaman yang tertukar. |
## 14.4 Protokol Pemulihan Layanan Pasca Kegagalan Sistem
Jika server mengalami pemadaman listrik mendadak atau kegagalan perangkat keras:
1. Nyalakan server dan masuk ke terminal host.
2. Periksa integritas database SQLite:
```bash
sqlite3 data/app.db "PRAGMA integrity_check;"
```
*Hasil normal:* `ok`.
3. Bersihkan sisa kunci pekerjaan (*stale jobs*) yang tertinggal dalam status running:
```bash
sqlite3 data/app.db "UPDATE jobs SET status='failed', error='Server restart recovery' WHERE status='running';"
```
4. Jalankan ulang seluruh stack kontainer menggunakan `./start.sh`.
5. Verifikasi fungsionalitas sistem melalui endpoint `/api/health`.

# Automated Quality Control & Visual Verification Report
**Audit Date & Time**: 2026-08-27T07:25:15Z
**Application**: Dataset Enrichment & Retraining App (FastAPI + Vite/React)
**Viewport Resolution**: 1440x900 (Desktop Viewport)
**Color Scheme**: Dark Mode Native
**Output Directory**: `/home/asus/feedmill/reTraining/screenshots`
**Overall Verdict**: **100% PASS (21 / 21 Items Verified)**
---
## 1. Executive Summary
An independent, automated Quality Control audit was conducted across all 21 captured screenshot artifacts. All targets conform strictly to the 1440x900 pixel resolution specification, exhibit high graphical entropy (> 2.0, proving non-blank/complex UI contents), and maintain **100% pairwise uniqueness with ZERO SHA-256 hash collisions** across all captures. Critical viewports including Triage Crop Grid, Triage Scatter Plot, Outlier Filter, Exemplar Filter Panel, and Live Workflow Progress States are distinctly rendered and verified.

## 3. Pairwise Uniqueness & Hash Collision Audit
- **Total Screenshots Verified**: 21
- **Unique SHA-256 Hashes**: 21 / 21
- **Hash Collisions Detected**: 0
- **Collision Audit Result**: ✅ **PASSED** (All 21 screenshot files are strictly distinct bitwise).
---
## 4. Visual & Technical Fidelity Checklist
- [x] **Zero Missing Screenshots**: All 21 target files exist and are verified.
- [x] **Resolution Compliance**: Every file conforms strictly to 1440x900 RGB PNG specifications.
- [x] **Pairwise Uniqueness**: ZERO duplicate images; all 21 items have distinct SHA-256 hashes.
- [x] **Triage Crop Grid & Scatter**: Container scrolling on `main.roboflow-main` captures both Triage Scatter SVG (scrollTop=680) and Crop Grid cards (scrollTop=1350).
- [x] **Exemplar Filter Panel**: Canvas prompt interaction activates `pool.active` rendering the `<ExemplarFilterPanel />` in the sidebar.
- [x] **Workflow Progress State**: Live running training job (#1600) with real-time logs, epoch progress bar, and loss curves captured in `21_workflow_progress_states.png`.
- [x] **Full Modals & Dialogs**: Project Creation, SAM3 Auto-Annotate, Mass Auto-Annotate, and Merge Target modals captured with full interactive backdrops.
- [x] **Real Data Fixtures**: All views populated with authentic project records (Project ID 5 `sack`, 184 batches, YOLO models v1–v5 benchmark tables).
- [x] **No Visual Artifacts / Blank Displays**: Graphical entropy range > 2.8 across all captures, confirming rich and detailed UI component renderings.

# Chapter 1
chapters.append("""# Bab 1: Ringkasan Sistem & Arsitektur Pipeline Data
Sistem retraining dan live counting karung pakan adalah platform vision berbasis deep learning terintegrasi untuk otomatisasi pelabelan, kurasi dataset, penyetelan halus (*fine-tuning*) model deteksi YOLO, serta verifikasi penghitungan objek karung pada konveyor transfer pabrik pakan ternak. Sistem dirancang guna menggantikan proses anotasi manual berulang serta memberikan jaminan stabilitas data latih antar-generasi model.
## 1.1 Latar Belakang & Tujuan Rekayasa
Operasional pabrik pakan menghadapi tantangan variasi visual konveyor: pergantian jenis karung (warna, corak, bahan laminasi), perubahan pencahayaan alami shift kerja, pergeseran sudut kamera CCTV, serta variasi kecepatan konveyor. Peningkatan akurasi model AI menuntut siklus retraining berkala yang cepat, terukur, dan tidak merusak performa deteksi sebelumnya.
Tujuan rekayasa platform:
1. **Otomatisasi Pelabelan Citra**: Memanfaatkan arsitektur Segment Anything Model 3 (Meta SAM3) berbasis prompt teks zero-shot untuk menghasilkan bounding box dan poligon instan.
2. **Jaminan Pembagian Data Valid**: Menerapkan algoritma *stable validation split* deterministik berbasis fungsi hash SHA-1 sehingga citra validasi tidak pernah bocor ke data latih.
3. **Penyetelan Halus Terkontrol**: Melatih arsitektur YOLO11 secara efisien dengan manajemen VRAM dinamis serta pembersihan direktori temporer otomatis.
4. **Verifikasi Penghitungan Nyata**: Menyediakan mesin pelacakan multi-lapisan (ByteTrack dan LineCrossCounter pada batas atas $y_1$) berkecepatan 146 FPS untuk memverifikasi akurasi terhadap data acuan kebenaran (*ground truth*).
## 1.2 Alur Pipeline 8 Tahap (8-Stage End-to-End Retraining Pipeline)
Alur pemrosesan data end-to-end terbagi menjadi 8 tahap berurutan:
```
[1. Video Archive / CCTV Ingest (06:00 Shift)]
│ (OCR Timestamp & Video Metadata)
▼
[2. Video Library & FFmpeg Frame Extractor]
│ (Range Streaming, Sampling at 1.0 FPS)
▼
[3. SAM3 Grounding Engine (Singleton CUDA)]
│ (Single set_image, Multi-Prompt Grounding, Exemplars)
▼
[4. Roboflow-Replica Review Canvas]
│ (Polygon Vertex/BBox Edit, Hotkeys, Source Tracking)
▼
[5. Data Prep, Outlier Triage & Augmentation]
│ (Score/Area/Aspect Keep-Ranges, Scatter Plot, Crop Grid)
▼
[6. Master Dataset Freezing & Stable Val Split]
│ (SHA1 Hash-based Val Split, Frozen Rules Snapshot, YOLO TXT)
▼
[7. YOLO Retraining & Model Comparison Benchmark]
│ (VRAM Auto-Tuning, Fine-Tuning, Base vs New mAP Comparison)
▼
[8. Live Inference Counter & Headless Accuracy Benchmark]
│ (ByteTrack, LineCrossCounter on y1, WebRTC/WHEP, GT Benchmark)
```

## 1.3 Peran Komponen Arsitektur Utama
Sistem terdiri dari enam komponen komputasi independen:
1. **Frontend Web Studio (Port 8080 / 5173)**: Antarmuka Single Page Application (SPA) berbasis React 19 dan Vite 7. Mengimplementasikan kanvas review berlatar gelap, visualisasi scatter plot SVG interaktif, tabel benchmark delta akurasi, dan panel kontrol live video WebRTC.
2. **Backend Application Server (Port 8000)**: Server REST API asinkron berbasis FastAPI dan Uvicorn (Python 3.12). Menangani streaming video HTTP 206, orkestrasi antrean pekerjaan, parser OCR, manipulasi dataset, dan interfacing model.
3. **GPU Singleton Engine Manager**: Modul resident CUDA yang mengelola model SAM3 (~3.9 GB VRAM dasar) dan proses training YOLO secara mutual eksklusif menggunakan mekanisme `jobs.gpu_lock` (timeout 20 detik).
4. **MediaMTX Streaming Server (Port 8554 & 8889)**: Gateway video multi-protokol yang menerima feed RTSP H.264/H.265 dari kamera Dahua CCTV (:8554) dan mentransmisikan ulang melalui protokol WebRTC WHEP berlatensi rendah (:8889) langsung ke peramban.
5. **Algoritma Tracking & Line Crossing**: Mesin pelacakan ByteTrack dipadukan dengan logika tripwire `LineCrossCounter` yang membaca tepi atas karung ($y_1$) untuk mencegah manipulasi perhitungan akibat deformasi fisik karung.
6. **SQLite WAL Database & Filesystem Storage**: Database SQLite (`data/app.db`) dalam mode Write-Ahead Logging (WAL) untuk persistensi metadata relasional, dipadukan dengan direktori file terstruktur untuk penyimpanan citra mentah, label teks YOLO, dan file bobot `.pt`.
## 1.4 Prinsip Desain: Hardware Agnosticism, Portabilitas & Pencegahan Drift
1. **Agnostisisme Perangkat Keras**: Sistem tidak mematok konfigurasi GPU tertentu pada kode sumber statis. File inisialisasi `start.sh` mendeteksi ketersediaan NVIDIA Container Device Interface (CDI) secara dinamis dan menginjeksi parameter ke `docker-compose.override.yml`. Jika GPU tidak terdeteksi, sistem beralih otomatis ke mode fallback CPU tanpa mengalami crash.
2. **Portabilitas Lingkungan**: Menggunakan manajer paket `uv` dan lockfile deterministik untuk Python, serta Nginx reverse proxy yang menyamakan jalur routing `/api/` antara kontainer Docker dan server pengembangan lokal.
3. **Pencegahan Konfigurasi Drift**: Seluruh konfigurasi sensitif (seperti `HF_TOKEN`) dibaca eksklusif dari file `.env`. Jalur direktori internal selalu menggunakan relasi path relatif terhadap basis data aplikasi.

# Chapter 2
chapters.append("""# Bab 2: Panduan Setup, Instalasi & Eksekusi Lingkungan Kerja
Bab ini memuat instruksi operasional untuk menjalankan sistem pada dua mode eksekusi: kontainer produksi Docker (dengan akselerasi GPU) dan lingkungan pengembangan lokal (*local development*).
## 2.1 Prasyarat Sistem & Dependensi Perangkat Keras
Konfigurasi perangkat keras dan dependensi minimum:
- **Prosesor (CPU)**: x86_64 Quad-Core 2.5 GHz atau lebih tinggi.
- **Memori Utama (RAM)**: Minimum 16 GB DDR4 (direkomendasikan 32 GB untuk caching dataset besar).
- **Akselerator Grafis (GPU)**: NVIDIA GPU dengan VRAM minimum 8 GB (arsitektur Turing, Ampere, Ada Lovelace, atau Blackwell) dan driver NVIDIA versi 535+.
- **Penyimpanan**: NVMe SSD dengan ruang kosong minimum 100 GB.
- **Sistem Operasi Host**: Ubuntu Linux 22.04 LTS atau 24.04 LTS.
- **Perangkat Lunak**: Docker Engine 27.0+, Docker Compose v2.20+, NVIDIA Container Toolkit, Git, FFmpeg, curl.
## 2.2 Metode Eksekusi 1: Docker Compose dengan Akselerasi GPU (Produksi)
Docker Compose adalah metode standar pada deployment server industri.
Langkah 1: Kloning repositori dan persiapkan berkas konfigurasi lingkungan:
```bash
cd /home/asus/feedmill/reTraining
cp .env.example .env
```
Langkah 2: Konfigurasikan token Hugging Face dan jalur arsip video pada `.env`:
```ini
HF_TOKEN=hf_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
VIDEO_ARCHIVE_HOST=/home/asus/feedmill/data/archive
WEB_PORT=8080
```
Langkah 3: Jalankan skrip inisialisasi otomatis:
```bash
./start.sh
```
Skrip `start.sh` akan memverifikasi keberadaan `docker`, memeriksa ketersediaan GPU via `nvidia-smi`, menghasilkan konfigurasi override CDI, membangun citra kontainer backend dan frontend, lalu mengaktifkan layanan pada latar belakang (*detached mode*).
Langkah 4: Verifikasi status kontainer:
```bash
docker compose ps
```
Hasil verifikasi yang valid menunjukkan dua kontainer berstatus `Up`:
- `retraining-backend-1` (Port 8000)
- `retraining-frontend-1` (Port 8080)
## 2.3 Metode Eksekusi 2: Pengembangan Lokal (uv & npm)
Mode pengembangan lokal digunakan saat pengujian kode sumber secara cepat tanpa proses build image Docker.
Langkah 1: Instal dependensi Python backend menggunakan `uv`:
```bash
# Pastikan uv telah terpasang pada host
curl -LsSf https://astral.sh/uv/install.sh | sh
# Instal seluruh dependensi backend
uv pip install -r requirements.txt
```
Langkah 2: Instal dependensi Node.js frontend:
```bash
cd frontend
npm install
cd ..
```
Langkah 3: Jalankan backend FastAPI (Terminal 1):
```bash
uv run uvicorn backend.main:app --host 0.0.0.0 --port 8000 --reload
```
Langkah 4: Jalankan frontend Vite dev server (Terminal 2):
```bash
npm --prefix frontend run dev -- --host 0.0.0.0
```
Aplikasi web lokal dapat diakses melalui peramban pada alamat `http://localhost:5173`.
## 2.4 Konfigurasi File .env & Manajemen Kredensial
File `.env` terletak pada direktori akar repositori dan tidak boleh diikutsertakan ke dalam version control publik.
Tabel parameter konfigurasi `.env`:
| Nama Variabel | Nilai Default / Contoh | Tipe | Deskripsi Operasional |
|---|---|---|---|
| `HF_TOKEN` | `hf_AbCdEf...` | String | Token otentikasi Hugging Face untuk mengunduh bobot Meta SAM3. |
| `VIDEO_ARCHIVE_HOST` | `/home/asus/feedmill/data/archive` | Path | Jalur direktori arsip video CCTV pada host machine. |
| `WEB_PORT` | `8080` | Integer | Port Nginx frontend yang diekspos ke jaringan lokal host. |
| `BACKEND_PORT` | `8000` | Integer | Port FastAPI backend service. |
| `RTSP_URL` | `rtsp://192.168.192.96:8554/cam` | URL | URL stream RTSP kamera conveyor dari MediaMTX. |
| `WHEP_URL` | `http://192.168.192.96:8889/cam/whep` | URL | Endpoint WebRTC WHEP untuk pemutaran video langsung di UI. |
## 2.5 Pemeriksaan Kesehatan Sistem (Health Check)
Untuk menguji kesiapan layanan backend, jalankan perintah curl berikut:
```bash
curl -s http://localhost:8000/api/health | jq .
```
Respons JSON yang valid:
```json
{
"status": "ok",
"gpu_available": true,
"device": "cuda:0",
"sam3_loaded": false,
"active_jobs": 0
}
```

# Chapter 3
chapters.append("""# Bab 3: Manajemen Proyek & Taksonomi Kelas
Bab ini memandu operator dalam menginisialisasi proyek baru, menetapkan geometri anotasi, menyusun taksonomi kelas deteksi, serta memetakan teks prompt untuk model segmentasi otomatis.
## 3.1 Struktur Proyek & Ruang Kerja Terisolasi
Setiap proyek deteksi merepresentasikan satu target fisik spesifik pada lini produksi (misalnya deteksi karung pakan ayam 50kg, karung pakan ikan, atau palet konveyor). Seluruh aset citra, file anotasi, subset validasi, dan versi model tersimpan secara terisolasi di dalam direktori `data/projects/<slug>/`.
![Antarmuka Manajemen Proyek](screenshots/01_projects_page.png)
*Gambar 1: Antarmuka Manajemen Proyek (Projects Overview).* Menampilkan kartu ringkasan proyek aktif, model dasar YOLO primer dan sekunder, taksonomi kelas dengan kuantitas objek terdeteksi, statistik pembagian data latih/validasi, serta tombol navigasi modul.
*(English label: Projects Overview Page)*
## 3.2 Pembuatan Proyek Baru & Parameter Awal
Untuk membuat proyek baru, klik tombol `+ New project` pada bagian atas halaman Projects. Sistem akan membuka form modal pembuatan proyek.
![Form Pembuatan Proyek Baru](screenshots/02_project_create_modal.png)
*Gambar 2: Form Pembuatan Proyek Baru (New Project Modal).* Konfigurasi nama proyek, jenis geometri anotasi (BBox atau Polygon), rasio langkah pembagian validasi (*val split stride*), jalur arsip video, dan penetapan prompt teks SAM3 awal untuk setiap kelas.
*(English label: Project Creation Modal)*
Parameter pada form pembuatan proyek:
1. **Project Name**: Nama identifikasi proyek (misalnya `Feedmill Sack Counter`). Nama ini akan diubah menjadi format URL slug (contoh `feedmill-sack-counter`).
2. **Label Type (Geometri)**:
- `bbox` (Bounding Box): Format koordinat segi empat $[x_{\\text{min}}, y_{\\text{min}}, x_{\\text{max}}, y_{\\text{max}}]$. Direkomendasikan untuk deteksi objek reguler dan kecepatan inferensi maksimal.
- `polygon`: Format koordinat poligon segmentasi multi-titik $[(x_1, y_1), (x_2, y_2), \\dots]$. Direkomendasikan untuk objek saling tumpang tindih (*heavy occlusion*).
*Perhatian: Jenis geometri terkunci permanen setelah batch pertama digabungkan ke dataset.*
3. **Val Split (Langkah Validasi)**: Nilai integer $N$ (default $5$). Menentukan bahwa setiap citra ke-$N$ secara konsisten dialokasikan sebagai data validasi (rasio $1/N = 20\\%$).
4. **Video Archive Root**: Jalur direktori arsip video CCTV (default `/videos`).
5. **Model Checkpoint**: Opsi untuk mengunggah bobot awal `.pt` (misalnya `v4-best.pt`). Jika disediakan, sistem secara otomatis mengekstrak nama kelas dari metadata bobot (`model.names`).
## 3.3 Taksonomi Kelas & Pemetaan Prompt Teks
Tabel definisi kelas dan pemetaan prompt pada proyek deteksi karung pakan:
| ID Kelas | Nama Kelas | Warna Swatch | Prompt Teks SAM3 | Deskripsi Objek Fisik |
|---|---|---|---|---|
| `0` | `sack` | `#3b82f6` (Biru) | `white woven plastic sack on conveyor belt` | Karung pakan plastik tenun putih yang melintas di konveyor. |
| `1` | `sack_damaged` | `#ef4444` (Merah) | `torn damaged sack leaking feed powder` | Karung sobek, bocor, atau kemasan rusak parah. |
| `2` | `person` | `#10b981` (Hijau) | `worker operator person handling bags` | Operator atau pekerja pabrik di sekitar konveyor. |
Peraturan kaskade perubahan kelas:
- Penambahan kelas baru memperbarui entri tabel `project_classes` dan menambahkan kunci kelas pada `data.yaml`.
- Penghapusan kelas memicu pembersihan seluruh anotasi kelas tersebut pada database dan disk, serta melakukan re-indeks penomoran ID kelas yang lebih tinggi untuk mencegah celah indeks (*gap index*).
- Penghapusan kelas terakhir pada proyek diblokir oleh sistem untuk menjaga integritas skema.

# Chapter 4
chapters.append("""# Bab 4: Pengelolaan Video Archive & Siklus Kerja 24 Jam
Bab ini menguraikan mekanisme pengorganisasian arsip rekaman CCTV, konversi stempel waktu video melalui Optical Character Recognition (OCR), dan pemindaian otomatis keberadaan truk pengangkut.
## 4.1 Logika Siklus Kerja 24 Jam (Shift 06:00)
Pabrik pakan ternak menerapkan siklus kerja 24 jam yang dimulai pukul 06:00 pagi dan berakhir pukul 05:59 pagi pada hari berikutnya. Sistem mengelompokkan rekaman video berdasarkan siklus kerja operasional pabrik, bukan berdasarkan tanggal kalender standar tengah malam (00:00).
Formula penetapan tanggal siklus kerja ($D_{\\text{siklus}}$):
$$D_{\\text{siklus}} = \\begin{cases} D_{\\text{kalender}}, & \\text{jika } t_{\\text{rekam}} \\ge 06:00:00 \\\\ D_{\\text{kalender}} - 1 \\text{ hari}, & \\text{jika } t_{\\text{rekam}} < 06:00:00 \\end{cases}$$
Contoh: Video yang direkam pada tanggal 14 Agustus 2026 pukul 02:30:00 dini hari akan dikelompokkan ke dalam **Siklus 13 Agu 2026**.
![Video Archive & Siklus Produksi](screenshots/03_library_video_archive.png)
*Gambar 3: Video Archive & Siklus Produksi 24 Jam (Library Page).* Panel siklus kerja harian pada sisi kiri, indikator validasi OCR (lingkaran amber untuk jam belum terverifikasi), status deteksi truk v4, rincian resolusi/durasi video, dan tombol aksi pemotongan.
*(English label: Video Archive & Cycles Tree)*
## 4.2 Ekstraksi Jam Video melalui OCR & Koreksi Manual
Kamera CCTV industri melakukan pembakaran stempel waktu (*burned-in timestamp*) langsung pada piksel video pojok kanan atas atau kiri bawah. Modul `backend/video_clock.py` mengekstrak koordinat waktu tersebut menggunakan metode pencocokan template (*template matching*) 12 glif angka (0 sampai 9, `:`, dan spasi).
Prosedur penanganan stempel waktu:
1. Sistem membaca frame pertama video dan melakukan crop area koordinat jam.
2. Hasil OCR disimpan pada tabel `video_clock` sebagai teks waktu lokal (*wall-clock time* format `HH:MM:SS`) untuk menghindari pergeseran akibat konversi zona waktu UTC/WIB di peramban.
3. Apabila skor kecocokan glif OCR berada di bawah ambang batas ($<0.85$), baris siklus ditandai dengan ikon lingkaran amber (perlu verifikasi).
4. Operator dapat mengklik teks waktu pada antarmuka dan mengetikkan koreksi jam secara manual.
## 4.3 Pemindaian Truk Massal Terotomatisasi (Truck Scan v4)
Tidak semua video arsip memuat aktivitas bongkar muat karung. Untuk menghemat waktu anotasi, sistem menyediakan fitur pemindaian truk menggunakan model `v4-best.pt`.
Langkah operasional:
1. Buka halaman Library proyek (`/projects/<id>`).
2. Klik tombol `Cek truk (v4)` pada header tabel arsip.
3. Server mengeksekusi inferensi berkecepatan tinggi pada sampel frame video terpilih (1 frame per 10 detik).
4. Kolom `Truk` pada tabel akan menampilkan rasio keberadaan truk:
- **Badge Hijau (contoh `12/12`)**: Truk terdeteksi konsisten, video siap dipotong dan dianotasi.
- **Badge Merah (`tanpa truk`)**: Konveyor dalam keadaan kosong/mati, video dapat dilewati.
- **Badge Abu-abu (`belum dicek`)**: Video baru yang belum dipindai.

chapters.append("""# Bab 5: Pemotongan Video & Ekstraksi Frame
Bab ini menjelaskan teknik isolasi segmen rekaman video operasional dan ekstraksi frame citra beresolusi penuh untuk persiapan dataset pelatihan.
## 5.1 Editor Pemotongan Video (Trim Page)
Modul pemotongan video memanfaatkan protokol HTTP 206 (*Partial Content Range Streaming*) pada backend FastAPI (`/projects/{id}/video?rel=...`). Protokol ini memungkinkan peramban melakukan scrubbing timeline video secara instan tanpa mengunduh keseluruhan berkas video berukuran gigabyte.
![Editor Pemotongan Video](screenshots/04_trim_page.png)

*(English label: Video Trim & Frame Extractor)*
## 5.2 Penentuan Rentang Timecode & Sampling FPS
Langkah operasional pemotongan video:
1. Geser playhead video ke titik awal saat karung pertama mulai bergerak di atas konveyor.
2. Klik tombol `Use playhead` pada slider **Start** untuk mengunci waktu In.
3. Geser playhead ke titik akhir saat karung terakhir melintasi garis konveyor.
4. Klik tombol `Use playhead` pada slider **End** untuk mengunci waktu Out.
5. Tentukan nilai **Frames per second (FPS)**:
- **Nilai Standar (1.0 FPS)**: Mengekstrak 1 frame per detik. Pilihan optimal untuk konveyor berkecepatan normal (0.3 sampai 0.6 m/s) guna menghindari duplikasi visual yang berlebihan.
- **Nilai Tinggi (2.0 FPS)**: Digunakan pada konveyor cepat atau kondisi karung bertumpuk rapat.
- **Nilai Rendah (0.5 FPS)**: Digunakan untuk perekaman durasi panjang dengan variasi visual minimal.
6. Periksa badge kalkulasi otomatis: `<durasi detik> of video -> <N> frame(s)`.
7. Klik tombol `Extract frames`.
## 5.3 Manajemen Antrean Batch Hasil Ekstraksi
Setelah tombol `Extract frames` ditekan, backend mendaftarkan pekerjaan ke antrean `jobs` dan mengeksekusi perintah FFmpeg secara asinkron:
```bash
ffmpeg -ss <start_sec> -to <end_sec> -i <video_path> -vf fps=<fps> -q:v 2 frames/%06d.jpg
```
Frame citra disimpan dengan format penomoran enam digit (`000001.jpg`, `000002.jpg`, dst.) di dalam direktori `data/projects/<slug>/batches/<batch-id>/frames/`.
![Tabel Manajemen Batch](screenshots/05_batches_page.png)

Aksi operasional pada tabel batch:
- **Checkbox Seleksi**: Memilih satu atau beberapa batch untuk proses penggabungan (*merge*).
- **Auto-annotate**: Membuka dialog pelabelan otomatis SAM3 untuk batch tunggal.
- **Review (n/N)**: Masuk ke modul kanvas review anotasi interaktif.
- **Reset Auto**: Menghapus seluruh anotasi otomatis (`source='auto'`) dan mempertahankan anotasi manual (`source='manual'`).
- **Download Annotations (.zip)**: Mengunduh arsip ZIP berisi citra dan file label teks YOLO.
- **Restore from .zip**: Memulihkan anotasi dari berkas cadangan ZIP eksternal.

# Chapter 6
chapters.append("""# Bab 6: Pelabelan Otomatis Menggunakan SAM3 Grounding Engine
Bab ini menguraikan arsitektur model segmentasi Meta SAM3, mekanisme pelabelan otomatis berbasis prompt teks zero-shot, panduan interaksi kotak contoh (*exemplar*), serta penggunaan modul Playground.
## 6.1 Arsitektur SAM3 Zero-Shot Grounding
Meta Segment Anything Model 3 (SAM3) adalah arsitektur *vision foundation model* dengan kemampuan melokalisasi dan mengelompokkan objek citra secara zero-shot berdasarkan deskripsi bahasa alami (*open-vocabulary grounding*).
Arsitektur inferensi SAM3 diimplementasikan melalui modul `backend/sam3_engine.py`:
- Model memuat bobot Vision Transformer (ViT) dasar dengan konsumsi VRAM awal ~3.9 GB.
- **Eksekusi Tunggal `set_image()`**: Tulang punggung fitur visual (*vision backbone*) memproses citra frame hanya satu kali dan menyimpan representasi fitur (*backbone_out*) pada cache memori GPU.
- **Evaluasi Multi-Prompt**: Kepala penyelaras teks (*grounding head*) dieksekusi berulang kali pada representasi fitur yang sama untuk setiap kelas prompt tanpa mengulang komputasi backbone.
## 6.2 Auto-Labeling Batch Tunggal & Exemplar Tuning
Untuk menjalankan pelabelan otomatis pada batch tertentu, klik tombol `Auto-annotate` pada baris batch.
![Modal Auto-Anotasi SAM3 Tunggal](screenshots/06_batches_sam3_auto_annotate_modal.png)
*Gambar 6: Modal Auto-Anotasi SAM3 Tunggal (Auto-Annotate Modal).* Kanvas preview deteksi interaktif, slider ambang batas confidence, NMS IoU, filter ukuran minimum kotak, serta bidang gambar kotak exemplar positif dan negatif.
*(English label: Single-Batch SAM3 Modal)*
Parameter konfigurasi auto-labeling:
1. **Confidence Threshold (0.05 sampai 0.95, default 0.35)**: Skor probabilitas minimum deteksi. Naikkan nilai jika muncul deteksi palsu (*false positive*) pada latar belakang konveyor; turunkan nilai jika karung buram tidak terdeteksi.
2. **NMS IoU Threshold (0.0 sampai 0.9, default 0.0)**: Ambang batas Non-Maximum Suppression untuk mengeliminasi kotak tumpang tindih dari prompt berbeda (*cross-prompt NMS*). Nilai 0.0 mengaktifkan pembersihan tumpang tindih ketat.
3. **Min Box Size Fraction (0 sampai 50%, default 0%)**: Mengabaikan deteksi objek dengan luas area di bawah persentase tertentu terhadap total luas frame. Berguna untuk memfilter serpihan kecil atau noise debu.
4. **Interactive Exemplar Prompting**:
- **Kotak Positif (`+1`)**: Klik dan tarik (*drag*) kursor mouse pada objek karung yang tidak terdeteksi. SAM3 akan memprioritaskan fitur visual objek serupa.
- **Kotak Negatif (`-2`)**: Tekan tombol `Shift` + tarik kursor mouse pada objek non-target (misalnya kaki operator atau refleksi lantai). SAM3 akan mengabaikan pola visual tersebut.
5. Klik tombol `Run Preview` untuk mengevaluasi hasil penyesuaian parameter sebelum menyimpan ke database.
## 6.3 Auto-Labeling Massal Multi-Batch
Apabila operator memiliki puluhan batch rekaman yang baru diekstraksi, gunakan fitur auto-labeling massal.
![Modal Auto-Anotasi Massal](screenshots/07_batches_mass_auto_annotate_modal.png)
*Gambar 7: Modal Auto-Anotasi Massal (Mass Auto-Annotate Modal).* Pilihan engine pelabelan (SAM3 Zero-Shot, Base Model v4, atau Model Kustom), daftar centang batch target, dan tombol eksekusi antrean sekuensial.
*(English label: Mass Auto-Annotation Modal)*
Opsi engine pelabelan:
- **SAM3 Zero-Shot**: Menggunakan Meta SAM3 dengan prompt teks proyek. Sangat fleksibel untuk objek baru.
- **Project Base Model**: Menggunakan model YOLO proyek yang sedang aktif (misalnya `v4-best.pt`). Kecepatan inferensi jauh lebih tinggi dibandingkan SAM3.
- **Custom YOLO Model**: Menggunakan file checkpoint `.pt` khusus yang diunggah operator.
Seluruh proses massal dieksekusi secara sekuensial oleh worker backend di bawah proteksi `jobs.gpu_lock` untuk mencegah benturan VRAM.
## 6.4 SAM3 Global Playground
Modul Playground (`/sam3-playground`) menyediakan lingkungan uji coba terisolasi untuk menguji efektivitas prompt teks tanpa memengaruhi database proyek aktif.

Bab ini menguraikan fitur penyuntingan anotasi pada kanvas berlatar gelap, sistem koordinat ternormalisasi, navigasi tombol pintas keyboard, dan aturan kardinal anotasi objek konveyor.
## 7.1 Tata Letak Kanvas Gelap Roboflow-Replica
Modul Review (`/projects/{id}/review?batch=<batch_id>`) dirancang untuk kenyamanan mata operator selama sesi verifikasi panjang. Seluruh koordinat geometri disimpan dalam format mengambang ternormalisasi $0.0$ sampai $1.0$ terhadap dimensi lebar dan tinggi frame asli.
Format koordinat ternormalisasi:
$$x_{\\text{norm}} = \\frac{x_{\\text{piksel}}}{W_{\\text{frame}}}, \\quad y_{\\text{norm}} = \\frac{y_{\\text{piksel}}}{H_{\\text{frame}}}$$

*(English label: Canvas Review & Annotation)*
## 7.2 Prosedur Review Cepat Menggunakan Hotkeys
Antarmuka review mendukung kendali penuh berbasis keyboard (*keyboard-first workflow*):
Tabel daftar tombol pintas (Hotkeys):
| Tombol Pintas | Fungsi Operasional | Efek pada Sistem |
|---|---|---|
| `A` | **Approve Frame** | Menandai frame saat ini sebagai `approved` (hijau) dan otomatis berpindah ke frame berikutnya. |
| `X` | **Reject Frame** | Menandai frame saat ini sebagai `rejected` (merah) dan berpindah ke frame berikutnya. |
| `<-` / `->` | **Navigasi Frame** | Berpindah mundur atau maju satu frame pada timeline batch. |
| `N` | **Next Annotated** | Melompat langsung ke frame berikutnya yang memiliki objek anotasi. |
| `C` | **Copy Previous** | Menyalin seluruh anotasi dari frame sebelumnya ke frame aktif saat ini. |
| `Del` / `Backspace` | **Delete Shape** | Menghapus kotak atau poligon yang sedang aktif/terpilih. |
| `V` | **Toggle Tool** | Beralih mode antara kursor seleksi (*Select*) dan mode menggambar (*Draw*). |
| `1` sampai `9` | **Fast Reclass** | Mengubah kelas objek yang dipilih secara instan sesuai nomor urut kelas. |
| `Esc` | **Cancel / Deselect** | Membatalkan seleksi bentuk aktif atau menutup overlay dialog. |
## 7.3 Penyuntingan Vertex Poligon & Bounding Box
Manipulasi bentuk pada kanvas:
- **Bounding Box**: Klik objek untuk memunculkan 8 titik handle tepi. Tarik handle sudut untuk mengubah skala, atau tarik badan kotak untuk menggeser posisi.
- **Poligon Segmentasi**: Klik poligon untuk memunculkan titik-titik vertex bulat (`.handle-vertex`) dan titik tengah tepi (`.handle-midpoint`).
- Tarik `.handle-vertex` untuk memindahkan sudut kontur.
- Klik `.handle-midpoint` untuk menyisipkan titik sudut baru pada kontur poligon.
- Tekan tombol `Alt` + klik pada titik vertex untuk menghapus titik tersebut (jumlah titik minimum poligon adalah 3).
## 7.4 Quick Reclass Bar & Filmstrip Navigasi
Pada bagian atas kanvas review, bilah *Quick Reclass Bar* menyediakan akses satu klik untuk mengganti klasifikasi objek.

Status frame pada filmstrip:
- **Garis Tepi Hijau**: Frame berstatus disetujui (*approved*), siap digabungkan ke dataset master.
- **Garis Tepi Merah**: Frame berstatus ditolak (*rejected*), akan dilewati saat proses merge.
- **Garis Tepi Kuning/Abu-abu**: Frame berstatus tunda (*pending*), belum diperiksa oleh operator.
## 7.5 Panel Filter Exemplar In-Review
Operator dapat menyetel ulang deteksi SAM3 secara lokal langsung dari sidebar review tanpa perlu kembali ke halaman batch.

*(English label: In-Review Exemplar Filter Panel)*
## 7.6 Kebijakan Anotasi Kardinal: Penanganan Oklusi Garis Atas (y1)
Sistem penghitungan live counting mengandalkan pemicu tepi atas kotak karung ($y_1$). Oleh karena itu, operator wajib mematuhi aturan kardinal anotasi:
1. **Aturan Oklusi Tepi Atas**: Apabila tepi atas karung terhalang oleh kepala pekerja, tangan operator, atau karung lain yang menumpuk di atasnya, **jangan buat anotasi pada karung tersebut**. Membiarkan kotak deteksi dengan $y_1$ yang salah akan menyebabkan pemicuan ganda (*double triggering*) pada algoritma counting.
2. **Karung Terpotong Tepi Bawah**: Karung yang hanya terlihat sebagian pada bagian bawah namun memiliki tepi atas yang jelas **wajib dianotasi** hingga batas visual yang tampak.
3. **Pewarisan Anotasi Manual**: Setiap modifikasi manual yang dilakukan operator pada kanvas review akan mengubah status sumber anotasi menjadi `source='manual'`. Anotasi manual terlindungi dan tidak akan tertimpa jika fungsi auto-annotation dijalankan ulang.

# Chapter 8
chapters.append("""# Bab 8: Penyiapan Data, Triage Kualitas & Augmentasi
Bab ini membahas modul Data Prep sebagai gerbang kendali mutu (*quality gate*) sebelum data digabungkan ke dataset master, visualisasi scatter plot logaritmik, galeri crop grid, dan konfigurasi augmentasi sintetis.
## 8.1 Filter Pencilan (Outlier Triage Filter) Non-Destruktif
Modul Outlier Filter (`backend/triage.py`) melakukan evaluasi otomatis pada seluruh anotasi di dalam batch terpilih berdasarkan tiga metrik geometris tanpa menghapus data secara permanen (*non-destructive filtering*).
![Filter Outlier Kualitas Data](screenshots/13_data_prep_quality_outliers.png)
*Gambar 12: Filter Outlier Kualitas Data (Data Prep Outliers).* Tiga kartu filter keep-range untuk confidence score, persentase luas area kotak, dan aspect ratio, dilengkapi ringkasan kuantitas objek lolos/terfilter.
*(English label: Outlier Quality Filter)*
Tiga metrik penapisan outlier:
1. **Confidence Score (0.00 sampai 1.00)**: Menyingkirkan deteksi otomatis dengan tingkat keyakinan rendah yang berpotensi merupakan false positive.
2. **Box Area % (0.00% sampai 100.00%)**: Menyingkirkan objek yang terlalu kecil (noise debu konveyor) atau terlalu besar (artefak background yang mencakup seluruh layar).
3. **Aspect Ratio W/H (0.00 sampai 10.00)**: Menyingkirkan kotak deteksi yang terlalu pipih atau terlalu ramping vertikal yang tidak sesuai dengan proporsi fisik karung pakan standar.
Prinsip kerja triage rules:
- Anotasi yang berada di luar rentang batas (*keep-range*) ditandai sebagai `ignored`.
- Anotasi manual (`source='manual'`) memiliki preseden tertinggi dan **selalu dipertahankan** meskipun nilainya berada di luar batas filter.
- Frame yang kehilangan 100% anotasi akibat filter outlier akan ditahan (*held back*) dan tidak dimasukkan ke dalam dataset master untuk mencegah pencemaran citra latar belakang kosong yang tidak disengaja.
## 8.2 Konfigurasi Augmentasi Citra
Augmentasi data menghasilkan variasi citra sintetis untuk meningkatkan generalisasi model terhadap perubahan kondisi pabrik.
![Panel Konfigurasi Augmentasi](screenshots/14_data_prep_augmentation_panel.png)
*Gambar 13: Panel Konfigurasi Augmentasi Gambar (Augmentation Panel).* Pemilihan preset augmentasi (Off, Light, Medium, Aggressive) dan 9 slider penyesuaian parameter geometri serta fotometri.

Tabel preset dan parameter augmentasi:
| Parameter | Preset Light | Preset Medium (Default) | Preset Aggressive | Deskripsi Transformasi |
|---|---|---|---|---|
| `fliplr` | 0.5 | 0.5 | 0.5 | Probabilitas pembalikan horizontal citra (kiri ke kanan). |
| `flipud` | 0.0 | 0.0 | 0.2 | Probabilitas pembalikan vertikal citra (atas ke bawah). |
| `degrees` | 0.0° | 5.0° | 15.0° | Rentang rotasi acak derajat kemiringan. |
| `translate` | 0.05 | 0.10 | 0.20 | Translasi pergeseran posisi gambar secara acak. |
| `scale` | 0.10 | 0.20 | 0.50 | Skala pembesaran/pengecilan objek acak. |
| `hsv_h` | 0.01 | 0.015 | 0.03 | Variasi spektrum hue warna citra. |
| `hsv_s` | 0.3 | 0.5 | 0.7 | Variasi saturasi warna citra. |
| `hsv_v` | 0.2 | 0.3 | 0.5 | Variasi kecerahan/kegelapan (*value*) pencahayaan. |
| `mosaic` | 0.0 | 0.5 | 1.0 | Probabilitas penggabungan 4 potongan citra menjadi satu. |
*Invarian penting: Seluruh parameter augmentasi hanya diterapkan pada subset data latih (train). Subset data validasi (val) tidak pernah diaugmentasi agar evaluasi benchmark tetap murni.*
## 8.3 Analisis Sebaran Logaritmik & Marquee Selection
Scatter plot interaktif (`TriageScatter.jsx`) menyajikan visualisasi sebaran seluruh anotasi dalam grafik dua dimensi: Sumbu Y mewakili Confidence Score (0.0 sampai 1.0) dan Sumbu X mewakili Luas Area Kotak dalam skala logaritmik ($10^{-3}$ hingga $10^0$).
![Scatter Plot Triage Score vs Area](screenshots/11_review_triage_scatter_plot.png)
*Gambar 14: Scatter Plot Triage Score vs Area Logaritmik.* Titik-titik anotasi objek dengan garis batas penapisan merah putus-putus, seleksi area kotak (marquee tool), dan bilah penetapan keputusan manual (*verdict bar*).
*(English label: Triage Scatter Plot Log Scale)*
Fitur interaktif Scatter Plot:
- Garis putus-putus merah menandai batas keep-range aktif.
- Operator dapat mengklik dan menarik kursor untuk membuat kotak seleksi (*marquee selection*) pada sekumpulan titik anomali.
- Tombol aksi pada *Verdict Bar*:
- `Keep`: Menetapkan override manual agar objek terpilih selalu diikutsertakan.
- `Ignore`: Menetapkan override manual agar objek terpilih selalu dibuang.
- `Clear hand decisions`: Menghapus keputusan override manual.
## 8.4 Inspeksi Kualitas Melalui Crop Grid
Galeri Crop Grid (`TriageCropGrid.jsx`) menampilkan potongan thumbnail piksel dari setiap anotasi yang diurutkan dari skor terendah atau ukuran terkecil.
![Grid Crop Triage Objek](screenshots/10_review_triage_crop_grid.png)
*Gambar 15: Grid Crop Triage Objek (Triage Crop Grid).* Galeri 120 thumbnail potongan objek resolusi server, garis tepi berwarna penanda status, informasi skor dan persentase area, serta seleksi massal.

Fitur Crop Grid:
- Mengambil potongan gambar langsung dari backend secara cepat (`/api/projects/{id}/crop-grid`).
- Garis tepi hijau menunjukkan objek lolos filter, garis tepi abu-abu/merah menunjukkan objek terfilter.
- Operator dapat memilih beberapa thumbnail dan menerapkan keputusan `Keep` atau `Ignore` secara instan.
## 8.5 Modal Konfirmasi Penggabungan Dataset
Setelah operator memastikan parameter filter dan augmentasi telah optimal, klik tombol `Prepare & Merge Selected`.
![Modal Konfirmasi Merge Dataset](screenshots/15_data_prep_merge_target_modal.png)
*Gambar 16: Modal Konfirmasi Merge Dataset (Merge Target Modal).* Opsi target dataset (memperbarui dataset aktif atau membuat dataset baru), peringatan batch yang belum direview penuh, dan tombol konfirmasi penggabungan.
*(English label: Dataset Merge Target Modal)*
Logika penggabungan (*merge gate*):
- Jika terdapat batch yang belum berstatus 100% reviewed, sistem menampilkan kotak peringatan kuning. Operator wajib mencentang opsi persetujuan `Merge them unreviewed` untuk melanjutkan.
- Saat konfirmasi diberikan, sistem mengambil snapshot aturan triage aktif dan menyimpannya ke kolom `datasets.rules_json`.

# Chapter 9
chapters.append("""# Bab 9: Manajemen Dataset Master & Pembagian Validasi Permanen
Bab ini membahas struktur dataset master, mekanisme pembekuan data (*dataset freezing*), invarian pembagian validasi stabil berbasis hash kriptografis, dan integrasi dataset eksternal.
## 9.1 Mekanisme Pembekuan Dataset (Dataset Freezing)
Dataset master adalah kumpulan citra dan label teks terverifikasi yang siap digunakan untuk melatih model. Setiap operasi penggabungan (*merge*) bersifat atomik: citra frame disalin ke direktori `data/projects/<slug>/datasets/<id>/images/`, label YOLO diekspor ke `labels/`, dan konfigurasi `data.yaml` dihasilkan secara otomatis.
![Halaman Manajemen Dataset Master](screenshots/16_datasets_page.png)
*Gambar 17: Halaman Manajemen Dataset Master (Datasets Page).* Ringkasan dataset master, jumlah total citra, rasio pembagian data latih/validasi, riwayat versi aturan triage, dan bilah kalkulasi gabungan multi-dataset.
*(English label: Master Datasets & Split View)*
## 9.2 Invarian: Pembagian Validasi Stabil (Stable Validation Split)
Salah satu kesalahan fatal dalam sistem machine learning industri adalah pergeseran data validasi antar waktu (*data leakage / unstable split*). Apabila sebuah frame citra berada pada set validasi pada model v1, lalu berpindah ke set pelatihan pada model v2, maka perbandingan metrik mAP antar kedua model tersebut menjadi tidak valid.
Untuk menjamin stabilitas absolut, sistem mengimplementasikan algoritma hashing pada `backend/dataset.py:split_for()`:
```python
import hashlib
def split_for(project_id: int, batch_id: int, frame_stem: str, val_every: int = 5) -> str:
# Membentuk string identifikasi unik konten frame
key = f"{project_id}:{batch_id}:{frame_stem}".encode("utf-8")
hash_digest = hashlib.sha1(key).hexdigest()
# Mengonversi 8 karakter pertama hash ke integer
hash_int = int(hash_digest[:8], 16)
# Menentukan alokasi split secara deterministik
if hash_int % val_every == 0:
return "val"
return "train"
```
Karakteristik Pembagian Validasi Stabil:
1. **Deterministik Murni**: Penentuan status `train` atau `val` sepenuhnya ditentukan oleh nama file, ID batch, dan ID proyek.
2. **Kekebalan Mutasi**: Meskipun batch baru ditambahkan atau batch lama dihapus, frame yang pernah masuk ke subset `val` akan selalu tetap berada di subset `val` pada setiap dataset baru yang dibuat.
3. **Penyusunan File Disk**: Citra langsung disalin ke folder terpisah:
- `images/train/<batch-id>__<frame_idx>.jpg`
- `images/val/<batch-id>__<frame_idx>.jpg`
## 9.3 Integrasi Base Datasets Eksternal (Train-Only)
Sistem mendukung integrasi dataset luar (*base datasets*) melalui tabel `base_datasets`. Dataset eksternal ini umumnya berisi ribuan foto karung pakan dari pabrik lain atau domain publik.
Aturan isolasi base dataset:
- Seluruh citra dari base dataset dimasukkan **eksklusif ke subset data latih (`train`)**.
- Citra base dataset tidak pernah diizinkan masuk ke subset validasi (`val`) untuk memastikan benchmark akurasi proyek murni mencerminkan performa pada kamera lini produksi lokal.
## 9.4 Operasi Resync, Kombinasi Multi-Dataset & Ekspor ZIP
Aksi pada kartu dataset:
- **Resync Rules**: Menerapkan ulang aturan triage terbaru ke dataset yang telah ada. *Perhatian: Operasi ini bersifat destruktif terhadap snapshot aturan sebelumnya dan hanya boleh dilakukan jika terjadi pembaruan kebijakan mutu data.*
- **Combine Preview Strip**: Centang lebih dari satu kotak dataset pada halaman Datasets. Bilah atas akan menampilkan kalkulasi instan: `N selected · T unique images · X train / Y val`. Saat pelatihan model dijalankan, sistem menggabungkan dataset-dataset tersebut secara virtual tanpa duplikasi file.
- **Download (.zip)**: Mengunduh arsip dataset lengkap berstruktur standar YOLO (folder `images`, `labels`, dan `data.yaml`) untuk keperluan pelatihan eksternal.

Bab ini memandu prosedur penyetelan halus (*fine-tuning*) bobot YOLO11, pemantauan log pelatihan real-time, evaluasi komparatif metrik mAP, serta promosi bobot model terbaik.
## 10.1 Konfigurasi Pelatihan Model
Pelatihan model dilakukan melalui antarmuka Models (`/projects/{id}/models`).

*Gambar 18: Halaman Konfigurasi Training & Evaluasi Model (Models Page).* Panel konfigurasi parameter epoch, probe perangkat keras otomatis, pemilihan kombinasi dataset, serta tabel perbandingan metrik evaluasi model terhadap base model.
*(English label: YOLO Model Training & Metrics)*
Langkah konfigurasi pelatihan:
1. **Pilih Base Model Weights**: Pilih checkpoint dasar (misalnya `v4-best.pt` atau bobot pretrained Ultralytics `yolo11n.pt` / `yolo11n-seg.pt`).
2. **Target Classes**: Pilih kelas deteksi yang akan dilatih.
3. **Epochs**: Masukkan jumlah siklus pelatihan (default 50 epoch, rekomendasi 30 sampai 100 epoch untuk fine-tuning).
4. **Hardware Auto-Probe**: Sistem memeriksa kapasitas VRAM GPU host secara otomatis:
- VRAM < 8 GB: `batch=8, imgsz=640`
- VRAM 8 sampai 16 GB: `batch=16, imgsz=640`
- VRAM > 16 GB: `batch=32, imgsz=768`
- CPU Fallback: `batch=4, imgsz=512`
5. **Pilih Dataset Pelatihan**: Centang dataset master dan base dataset yang akan dilibatkan dalam pelatihan.
6. Klik tombol `Start Training`.
## 10.2 Manajemen Memori GPU & Eksekusi Training
Saat tombol pelatihan diklik:
1. Backend mengakuisisi kunci eksklusif GPU (`jobs.gpu_lock`).
2. Jika engine SAM3 sedang aktif di VRAM, sistem secara otomatis mengeksekusi `sam3_engine.release_engine()`, memanggil `torch.cuda.empty_cache()`, dan membersihkan memori agar 100% kapasitas VRAM dapat digunakan oleh proses pelatihan YOLO.
3. Skrip pelatihan `backend/training.py` mengeksekusi library Ultralytics dengan parameter optimal:
- Optimizer: `AdamW` atau `SGD` (otomatis)
- Cache mode: RAM caching jika RAM host > 16 GB, atau disk caching jika RAM terbatas.
- Workers: 4 thread loader.
## 10.3 Monitoring Progres Pelatihan Real-Time
Selama pelatihan berlangsung, antarmuka web menampilkan kartu pekerjaan aktif dengan terminal log interaktif.
![Monitoring Progres Pelatihan Real-Time](screenshots/21_workflow_progress_states.png)
*Gambar 19: Status Monitoring Progres Pelatihan Real-Time.* Indikator progres epoch aktif, utilisasi VRAM, kurva penurunan box_loss, cls_loss, dfl_loss, estimasi sisa waktu (ETA), dan tombol pembatalan pekerjaan.

- Metrik presisi dan recall per epoch.
- Tombol `Cancel`: Mengirimkan sinyal terminasi ke worker pelatihan dan membersihkan direktori sementara `runs/`.
## 10.4 Evaluasi Komparatif Like-for-Like
Setelah proses pelatihan selesai, modul `backend/evaluate.py` secara otomatis mengevaluasi performa model baru (`best.pt`) dan membandingkannya secara langsung (*like-for-like*) dengan model dasar (*base model*) menggunakan subset validasi yang identik (`data.yaml`).
Tabel metrik evaluasi model:
| Versi Model | Status | mAP50 | mAP50-95 | Precision | Recall | Signed Delta $\\Delta$ mAP50 | Status Keputusan |
|---|---|---|---|---|---|---|---|
| `v1` | Arsip | 0.884 | 0.612 | 0.891 | 0.875 | Basis Awal | Model Awal |
| `v2` | Arsip | 0.912 | 0.654 | 0.920 | 0.898 | `+0.028` (Hijau) | Ditingkatkan |
| `v3` | Arsip | 0.938 | 0.701 | 0.942 | 0.925 | `+0.026` (Hijau) | Ditingkatkan |
| `v4` | **Base Aktif** | 0.965 | 0.748 | 0.968 | 0.952 | `+0.027` (Hijau) | **Standar Produksi** |
| `v5` | Kandidat | 0.978 | 0.772 | 0.981 | 0.969 | `+0.013` (Hijau) | Siap Dipromosikan |
Penjelasan nilai Delta $\\Delta$:
- **Nilai Positif Hijau (`+0.013`)**: Menandakan model baru memiliki akurasi deteksi lebih unggul pada data validasi.
- **Nilai Negatif Merah (`-0.015`)**: Menandakan terjadi penurunan performa (*model regression*); model baru sebaiknya tidak dipromosikan.
## 10.5 Promosi Model Baru (Model Promotion)
Jika model kandidat (misalnya `v5`) terbukti menghasilkan delta mAP positif dan lolos pengujian:
1. Klik tombol `Use as base model` pada baris model tersebut.
2. Sistem secara atomik menyalin file bobot `data/projects/<slug>/models/5/best.pt` ke jalur model dasar proyek `data/projects/<slug>/base/model.pt`.
3. Model baru langsung aktif sebagai rujukan utama untuk modul pemindaian truk, auto-labeling, dan mesin live counting.

Bab ini menguraikan arsitektur penanganan aliran video kamera, kalibrasi posisi garis pemicu hitung (*tripwire*), algoritma pelacakan ByteTrack, dan penyetelan parameter histeresis.
## 11.1 Topologi Streaming MediaMTX
Kamera industri Dahua IPC-HFW1230 mengirimkan stream RTSP beresolusi 1080p / 704x576 pada 25 FPS ke server MediaMTX.
Topologi distribusi video:
```

Perbedaan fungsi kedua jalur:
1. **Jalur Browser (WHEP WebRTC)**: Ditransmisikan langsung dari MediaMTX ke elemen `<video>` peramban untuk monitoring operator dengan latensi ultra rendah tanpa membebani CPU backend.
2. **Jalur Inferensi Backend (RTSP)**: Dibaca oleh OpenCV backend untuk proses deteksi objek, pelacakan trajectory, dan kalkulasi garis hitung.

*(English label: Live Inference & Tripwire Panel)*
## 11.2 Penempatan Garis Hitung Interaktif & Kalibrasi Tripwire
Pada antarmuka Live Count (`/projects/{id}/live-count`), operator dapat mengkalibrasi garis tripwire secara visual langsung di atas kanvas video:
- Klik chip `Counting line` lalu klik posisi vertikal konveyor pada video untuk mengatur nilai `line_y` (koordinat normalisasi $0.0$ sampai $1.0$).
- Klik chip `Left edge` lalu klik batas kiri konveyor untuk mengatur nilai `line_x_start`.
- Klik chip `Right edge` lalu klik batas kanan konveyor untuk mengatur nilai `line_x_end`.
- Seluruh perubahan koordinat garis disimpan langsung ke database dan diterapkan secara instan ke mesin hitung (`/api/live-count/line`).
## 11.3 Algoritma Pelacakan ByteTrack & LineCrossCounter pada y1
Mesin pelacakan objek (`algoritma-batch/src/tracker.py` dan `counting.py`) mengombinasikan dua lapisan algoritma:
1. **ByteTrack Multi-Object Tracker**: Mengasosiasikan kotak deteksi antar frame menggunakan matriks kemiripan IoU dan Kalman Filter. ByteTrack mempertahankan ID objek meskipun karung mengalami oklusi sementara dengan parameter `track_buffer: 60` (mampu mengingat lintasan objek hingga 60 frame atau 2.4 detik).
2. **LineCrossCounter Triggering pada $y_1$**:
- Pemicu perhitungan didasarkan secara eksklusif pada **koordinat tepi atas kotak ($y_1$)**.
- Arah pergerakan dihitung dari perpindahan vektor lintasan: jika $y_1$ bergerak dari atas garis ($y_1 < \\text{line\\_y}$) melewati garis menuju ke bawah ($y_1 \\ge \\text{line\\_y}$), sistem mencatat peristiwa **Count In**.
- Sebaliknya, perpindahan dari bawah ke atas dicatat sebagai **Count Out**.
## 11.4 Penanganan Histeresis Lintasan & Parameter Tracking
Tabel parameter pelacakan live counting:
| Parameter | Rentang Nilai | Default | Deskripsi Fungsi |
|---|---|---|---|
| `line_y` | 0.10 sampai 0.90 | 0.50 | Posisi koordinat vertikal garis hitung tripwire pada frame. |
| `margin` | 10 sampai 100 px | 30 px | Lebar zona toleransi histeresis di sekitar garis hitung. |
| `entry_travel_min` | 10 sampai 200 px | 40 px | Jarak perpindahan minimum yang wajib ditempuh objek sebelum diizinkan memicu hitungan. Mencegah false trigger dari noise getaran konveyor. |
| `handoff_radius` | 20 sampai 250 px | 100 px | Radius pencarian serah-terima lintasan (*track handoff*). Jika ID objek terputus akibat oklusi mendadak, objek baru dalam radius ini mewarisi riwayat lintasan ID lama. |
| `unload_confirm_frames` | 1 sampai 30 frame | 5 frame | Jumlah frame konfirmasi sebelum status bongkar dikunci. |
| `min_area_scale` | 0.001 sampai 0.10 | 0.008 | Ambang batas fraksi luas area minimum objek yang diakui. |
| `conf` | 0.10 sampai 0.90 | 0.35 | Ambang batas confidence deteksi YOLO pada stream video. |
*Eliminasi Deteksi Semu (Ghost Box)*: Objek baru yang tiba-tiba terdeteksi pertama kali tepat di bawah garis hitung tanpa memiliki riwayat lintasan di atas garis diklasifikasikan sebagai *ghost detection* dan diabaikan oleh sistem.

Bab ini membahas modul evaluasi akurasi perhitungan berkecepatan tinggi tanpa antarmuka grafis (*headless counting bench*), integrasi data acuan kebenaran (*ground truth*), dan diagnosa kesalahan hitung.
## 12.1 Eksekusi Rekalkulasi Video Batch Headless (~146 FPS)
Modul Counting Bench (`/projects/{id}/counting-bench`) dirancang untuk memvalidasi akurasi model pada ratusan berkas video arsip secara cepat. Dengan menonaktifkan rendering antarmuka dan enkripsi transmisi WebSocket, pemrosesan video pada GPU dapat mencapai kecepatan **146 hingga 220 FPS** (dibandingkan mode live stream visual yang dibatasi pada 25 FPS).

*(English label: Counting Accuracy Benchmark Table)*
## 12.2 Impor Data Acuan Kebenaran (Ground Truth) dari Excel
Data acuan kebenaran (*ground truth*) adalah angka riil hasil penghitungan manual oleh petugas tally pabrik.
Metode pengisian Ground Truth:
1. **Impor Berkas Excel (`docs/GT.xlsx`)**: Sistem membaca berkas spreadsheet yang memuat kolom tanggal, nomor batch, dan kuantitas karung fisik, lalu memetakan nilainya ke tabel `count_runs` database secara otomatis.
2. **Koreksi Manual Langsung di Tabel**: Operator dapat mengklik kotak input angka pada kolom `Ground Truth` di antarmuka Counting Bench dan mengisikan angka hitungan fisik secara manual.
## 12.3 Evaluasi Metrik Signed Delta Error & Akurasi
Perhitungan selisih kesalahan dihitung menggunakan formula *Signed Delta Error* ($\\Delta$):
$$\\Delta = \\text{Counted}_{\\text{AI}} - \\text{Ground Truth}$$
Kategori status pada tabel benchmark:
- **Tanda Nol (`0`) Hijau**: Hitungan model AI persis sama dengan data fisik riil (Akurasi 100%).
- **Tanda Positif (`+N`) Kuning/Oranye**: Terjadi penghitungan berlebih (*overcounting*) sebanyak $N$ karung.
- **Tanda Negatif (`-N`) Merah**: Terjadi penghitungan kurang (*undercounting*) sebanyak $N$ karung.
Formula Akurasi Total Siklus:
$$\\text{Akurasi (\\%)} = \\left(1 - \\frac{\\sum |\\text{Counted}_{\\text{AI}} - \\text{Ground Truth}|}{\\sum \\text{Ground Truth}}\\right) \\times 100\\%$$
*Perhatian: Kalkulasi total akurasi hanya dihitung pada baris video yang telah memiliki nilai Ground Truth non-kosong.*

Tabel diagnosa masalah counting:
| Gejala Masalah | Penyebab Teknis Utama | Solusi Penanganan Rekayasa |

# Chapter 14
chapters.append("""# Bab 14: Invarian Domain, Penanganan Kasus Batas & Pemecahan Masalah
Bab penutup ini merangkum invarian domain yang tidak boleh dilanggar, panduan penanganan skenario kasus batas (*edge cases*), dan tabel pemecahan masalah teknis (*troubleshooting*).
## 14.1 Invarian Domain Tak Tergoyahkan (Core System Invariants)
Tiga invarian utama yang menjamin kebenaran ilmiah dan stabilitas sistem:
1. **Invarian 1: Pembagian Validasi Stabil (Stable Validation Split)**
*Prinsip*: Sekali sebuah frame citra dialokasikan ke dalam subset validasi (`val`), frame tersebut **wajib tetap berada di subset validasi selamanya** pada seluruh dataset masa depan.
*Rasional*: Mencegah kontaminasi data validasi ke data latih yang dapat menyebabkan nilai metrik mAP menjadi overoptimis dan tidak valid.
2. **Invarian 2: Eksekusi Tunggal `set_image()` per Frame pada SAM3**
*Prinsip*: Metode `Sam3Processor.set_image()` hanya dipanggil **satu kali per citra**. Pengujian multi-prompt dijalankan melalui pemanggilan berulang `set_text_prompt()` pada state fitur yang sama.
*Rasional*: Menghindari komputasi ulang Vision Transformer yang memboroskan siklus GPU dan memperlambat auto-labeling hingga 5 kali lipat.
3. **Invarian 3: Pemicuan Tripwire Berbasis Tepi Atas ($y_1$)**
*Prinsip*: Garis hitung tripwire hanya merespons lintasan koordinat puncak objek ($y_1$).
*Rasional*: Mencegah distorsi hitungan akibat perubahan panjang kantong karung saat tertekan di konveyor.
## 14.2 Penanganan Kasus Batas (Edge Cases)
Panduan sistem saat menghadapi skenario operasional khusus:
- **Kasus 1: Frame Tanpa Objek (Negative Sample Frame)**
Jika sebuah citra frame tidak memuat karung sama sekali (konveyor kosong), proses ekspor dataset tetap menghasilkan file label `.txt` kosong (ukuran 0 byte). File label kosong ini sangat penting bagi model YOLO untuk mempelajari representasi latar belakang (*background learning*) dan menekan false positive.
- **Kasus 2: Oklusi Parsial oleh Pekerja**
Jika karung tertutup sebagian oleh badan operator namun tepi atas ($y_1$) tetap terlihat jelas, buat anotasi hanya pada batas visual karung yang tampak. Jangan menebak bentuk di balik tubuh pekerja.
- **Kasus 3: Benturan Akses GPU Secara Bersamaan**
Jika pengguna memicu pelatihan model saat proses auto-labeling batch sedang berjalan, antrean tugas backend akan menahan perintah pelatihan dengan status `pending` hingga auto-labeling selesai atau dibatalkan oleh operator.
- **Kasus 4: URL RTSP Dimasukkan pada Form Live Count Web**
Peramban web standar tidak mendukung pemutaran langsung protokol RTSP. Jika operator memasukkan URL berawalan `rtsp://`, antarmuka akan menampilkan pesan kesalahan informatif dan memandu operator untuk memasukkan endpoint WebRTC WHEP MediaMTX (`http://...:8889/.../whep`).
## 14.3 Matriks Solusi Pemecahan Masalah (Troubleshooting Matrix)
Daftar masalah umum dan langkah penanganan cepat:
| Gejala Masalah | Indikasi Log / Error Code | Penyebab Akar | Tindakan Perbaikan |
|---|---|---|---|
| **Kegagalan Auto-Labeling SAM3** | `HTTP 401 Unauthorized` atau `HF ValidationError` | Token Hugging Face pada berkas `.env` belum diisi atau tidak memiliki izin akses ke repositori Meta SAM3. | Buka Hugging Face, buat User Access Token bertipe Read, setujui lisensi SAM3 di portal Meta, lalu perbarui variabel `HF_TOKEN` pada file `.env`. |
| **CUDA Out of Memory (OOM)** | `torch.cuda.OutOfMemoryError: CUDA out of memory` | Alokasi VRAM melampaui kapasitas fisik GPU saat training atau auto-labeling. | 1. Turunkan parameter ukuran batch (`batch=8` atau `batch=4`).<br>2. Turunkan resolusi citra latih (`imgsz=640` atau `512`).<br>3. Pastikan tidak ada proses Python zombie yang mengunci VRAM dengan menjalankan `fuser -v /dev/nvidia*`. |
| **Streaming WebRTC Gelap / Putus** | `WHEP connection failed (ICE timeout)` | MediaMTX belum menerima feed RTSP dari kamera atau koneksi jaringan VPN terputus. | 1. Uji koneksi ping ke IP kamera Dahua (`ping 192.168.192.96`).<br>2. Buka dashboard MediaMTX dan verifikasi bahwa stream `/cam` berstatus aktif.<br>3. Restart layanan MediaMTX. |
| **Video Scrubbing Lambat / Macet** | `HTTP 200 OK` (Bukan HTTP 206) | Nginx atau peramban tidak mendukung byte range request atau file video mengalami korupsi index moov atom. | 1. Jalankan perintah `qt-faststart` atau `ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4` untuk memindahkan metadata moov atom ke awal berkas.<br>2. Pastikan header `Accept-Ranges: bytes` aktif pada Nginx. |
| **Perbedaan Hitungan Signifikan pada Benchmark** | Delta bertanda merah besar (`-50` atau `+70`) | Posisi garis tripwire bergeser atau resolusi video berubah pasca pemeliharaan kamera. | 1. Buka halaman Live Count dan lakukan kalibrasi ulang garis `line_y`, `line_x_start`, dan `line_x_end`.<br>2. Periksa stempel waktu OCR pada Counting Bench untuk memastikan tidak ada batch rekaman yang tertukar. |
## 14.4 Protokol Pemulihan Layanan Pasca Kegagalan Sistem
Jika server mengalami pemadaman listrik mendadak atau kegagalan perangkat keras:
1. Nyalakan server dan masuk ke terminal host.
2. Periksa integritas database SQLite:
```bash
sqlite3 data/app.db "PRAGMA integrity_check;"
```
*Hasil normal:* `ok`.
3. Bersihkan sisa kunci pekerjaan (*stale jobs*) yang tertinggal dalam status running:
```bash
sqlite3 data/app.db "UPDATE jobs SET status='failed', error='Server restart recovery' WHERE status='running';"
```
4. Jalankan ulang seluruh stack kontainer menggunakan `./start.sh`.
5. Verifikasi fungsionalitas sistem melalui endpoint `/api/health`.

Verification and Audit Script for Milestone 3 Deliverables.
Checks:
1. XML well-formedness of docs/PANDUAN_SISTEM_LENGKAP.fodt
2. Presence and integrity of embedded images and styles in .fodt
3. PDF compilation and page count
4. Rendering pages to test PNGs via pdftoppm
5. Visual layout checks (no text clipping, crisp images, page breaks)
