# YOLOv7 Finetuned Figure/Graph Detection Model

This repository provides a YOLOv7 model finetuned for detecting figures and graphs in document images, such as those found in scientific papers. The model and code are open for public use and research.

## Model Overview

- **Base Model:** YOLOv7
- **Task:** Figure/Graph detection in document images
- **Finetuned on:** Custom dataset of figures and graphs

## Quick Start

### 1. Clone the repository and install dependencies

```bash
# Clone this repository
cd https://huggingface.co/vichetkao/graph_detection_model
python -m venv .venv
.\.venv\Scripts\activate
cd ../..
pip install -r requirements.txt
```

### 2. Download the Model Weights

Download the `best.pt` weights from this Hugging Face model page and place it in `run/train/weights/best.pt` or specify the path with `--weights`.

### 3. Run Detection

You can run detection on your images using the provided script:

```bash
python run_detect_testing.py --source "testing" --name testing_graph_bbox --device 0
```

- `--source`: Path to your image folder or file (default: `testing`)
- `--weights`: (Optional) Path to your model weights (`best.pt`)
- `--device`: Set to `0` for GPU or `cpu` for CPU inference

### 4. Output

- Results will be saved in `run/detect/testing_graph_bbox`
- YOLO label files will be in `run/detect/testing_graph_bbox/labels`

## Example Detection Results

```python
import subprocess
subprocess.call([
    "python", "run_detect_testing.py",
    "--source", "testing",
    "--weights", "run/train/weights/best.pt",
    "--device", "0"
])
```
