# Script Classification Benchmark

Holdout benchmark for six-class Tibetan script classification (540 page images).
Each class combines BDRC manuscript scans and synthetic benchmark images from
``Data/benchmark/``.

| Class | Images |
|-------|-------:|
| Danyig | 90 |
| Druma | 90 |
| Gyuyig | 90 |
| Pedri | 90 |
| Tsugdri | 90 |
| Uchen | 90 |

## Parquet schema

| Column | Type | Description |
|--------|------|-------------|
| `id` | string | BDRC page id or synthetic sample id |
| `image_bytes` | binary | JPEG/PNG page image |
| `script` | string | One of the six script families |
| `source` | string | ``bdrc`` or ``synthetic`` |
| `font_name` | string | Synthetic font name (version suffix stripped); empty for BDRC scans |

## Load in Python

```python
from datasets import load_dataset

repo = "BDRC/script-classification-Benchmark"
ds = load_dataset(repo, split="benchmark")
print(len(ds), ds.column_names)  # 540, ['id', 'image_bytes', 'script', 'source', 'font_name']

row = ds[0]
img = row["image_bytes"]  # bytes — same schema as BDRC training Parquet
print(row["source"], row["font_name"])
```

Page-level BDRC holdout ids for training exclusion live in
``benchmark_page_ids.json`` in the local ``Data/benchmark/`` folder.
