| # 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/``. |

| ## 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. |
