## Overview
|
| 32 |
+
|
| 33 |
+
Mô hình **D-FINE HGNetv2-X** được fine-tune cho bài toán nhận diện bố cục tài liệu (Document Layout Analysis). Mô hình sử dụng kiến trúc D-FINE tiên tiến với cơ chế Fine-grained Distribution Refinement (FDR) để tinh chỉnh bounding box, kết hợp backbone HGNetv2-B5 mạnh mẽ.

## Usage
|
| 72 |
+
|
| 73 |
+
### Option 1 — HuggingFace Transformers (recommended)
|
| 74 |
|
|
|
|
| 75 |
```bash
|
| 76 |
+
pip install transformers torch torchvision
|
| 77 |
+
# Clone D-FINE source code (bắt buộc)
|
| 78 |
git clone https://github.com/Peterande/D-FINE.git
|
| 79 |
cd D-FINE
|
| 80 |
pip install -r requirements.txt
|
| 81 |
```
|
| 82 |
|
| 83 |
+
```python
|
| 84 |
+
from transformers import AutoModel, AutoImageProcessor
|
| 85 |
+
from PIL import Image
|
| 86 |
+
|
| 87 |
+
processor = AutoImageProcessor.from_pretrained(
|
| 88 |
+
"ducnhan0804/dfine-x-obj-detection",
|
| 89 |
+
trust_remote_code=True
|
| 90 |
+
)
|
| 91 |
+
model = AutoModel.from_pretrained(
|
| 92 |
+
"ducnhan0804/dfine-x-obj-detection",
|
| 93 |
+
trust_remote_code=True
|
| 94 |
+
)
|
| 95 |
+
|
| 96 |
+
image = Image.open("path/to/your/document.png")
|
| 97 |
+
inputs = processor.preprocess(image)
|
| 98 |
+
outputs = model(inputs["images"], threshold=0.4)
|
| 99 |
+
results = processor.post_process_object_detection(outputs, threshold=0.4)
|
| 100 |
+
|
| 101 |
+
# results[0]["boxes"] → xyxy coordinates (tensor)
|
| 102 |
+
# results[0]["scores"] → confidence scores (tensor)
|
| 103 |
+
# results[0]["labels"] → class ids (tensor)
|
| 104 |
+
print(results)
|
| 105 |
+
```
|
| 106 |
+
|
| 107 |
+
> **Note:** `trust_remote_code=True` is required because this model uses custom `modeling_dfine.py`. The checkpoint (~1GB) is downloaded automatically to `~/.cache/huggingface/` on first run.
|
| 108 |
+
|
| 109 |
+
> **Important:** You must run this code from the D-FINE root directory so that the source code (`src/`) can be imported.
|
| 110 |
+
|
| 111 |
+
### Option 2 — D-FINE directly
|
| 112 |
|
|
|
|
|
|
|
| 113 |
```bash
|
| 114 |
+
git clone https://github.com/Peterande/D-FINE.git
|
| 115 |
+
cd D-FINE
|
| 116 |
+
pip install -r requirements.txt
|
| 117 |
+
```
|
| 118 |
+
|
| 119 |
+
```python
|
| 120 |
+
# Download checkpoint from HuggingFace
|
| 121 |
+
from huggingface_hub import hf_hub_download
|
| 122 |
+
|
| 123 |
+
weights = hf_hub_download(
|
| 124 |
+
repo_id="ducnhan0804/dfine-x-obj-detection",
|
| 125 |
+
filename="best_stg2.pth"
|
| 126 |
+
)
|
| 127 |
+
|
| 128 |
+
# Run inference using D-FINE's built-in script
|
| 129 |
+
# python tools/inference/torch_inf.py -c configs/dfine/custom/dfine_hgnetv2_x_custom.yml -r <weights_path> -i <image_path> -d cuda:0
|
| 130 |
+
```

## Limitations
|
| 184 |
+
|
| 185 |
+
- Trained on a specific document layout dataset; generalization to other document types is not guaranteed.
|
| 186 |
+
- Requires D-FINE source code to be cloned and available locally for inference.
|
| 187 |
+
- The checkpoint file is ~1GB in size.
