## Classes

| ID | Name | Description | Color | Count |
|----|------|-------------|-------|-------|
| 0 | `invoice_metadata` | Invoice number, date, header metadata | `#f59e0b` | 83 |
| 1 | `vendor_block` | Seller / vendor address block | `#22c55e` | 73 |
| 2 | `customer_block` | Client / customer address block | `#ef4444` | 74 |
| 3 | `table_block` | Line items table region | `#ec4899` | 76 |
| 4 | `line_item` | Individual line item row | `#8b5cf6` | 257 |
| 5 | `summary_block` | Totals / summary section | `#3b82f6` | 78 |
| 6 | `payment_block` | Payment / IBAN block | `#06b6d4` | 55 |
| 7 | `Column` | Table column header row | `#64748b` | 75 |

## Dataset Viewer schema

The `train` split uses COCO-style `objects` with `[x, y, width, height]` bboxes (top-left origin):

| Column | Type |
|--------|------|
| `image` | Image |
| `image_id`, `document_id`, `page_number`, `width`, `height` | int |
| `document_filename` | string |
| `objects.bbox` | list of `[x, y, w, h]` |
| `objects.category` | ClassLabel (8 layout regions) |
| `objects.area`, `objects.id` | float / int |

## Raw export layout

The original AnnotateEverything export is preserved under `raw_export/`:

## Usage

### Load with Hugging Face Datasets (recommended)

```python
from datasets import load_dataset

ds = load_dataset("AvoCahDoe/invoice-annotated-bbox")
example = ds["train"][0]
print(example["objects"])  # COCO-style bboxes + categories
example["image"].show()
```

### Load raw AnnotateEverything export

```python
import json
from huggingface_hub import hf_hub_download

ann_path = hf_hub_download("AvoCahDoe/invoice-annotated-bbox", "raw_export/annotations.json", repo_type="dataset")
with open(ann_path) as f:
    pages = json.load(f)
```

### Convert to YOLO (invoice-extractor)

```bash
python scripts/prepare_annotated_dataset.py
```
