Datasets:
| # OCR evaluation references | |
| `catalog.json` is a list of image records; `images/` contains the corresponding files. Paths are relative to this directory. The initial selection contains 1,000 images. | |
| Each record contains a stable `id`, image path, exact reference `text`, source `category`, reference `scope`, annotation `quality`, `reading_order_known`, optional word `regions`, and `source` provenance/rights. Source references and word regions are evaluation annotations, never hints to the OCR engine. | |
| Keep source transcripts exactly as supplied. `target_text_only` references cover a selected target instruction, not necessarily all text visible in the image. The initial references have silver quality; preserve that distinction when reporting results. Dataset records and image bytes should be reviewed together. | |
| The loading, metrics and runner code lives under `research/ocr_eval/evaluation/` in the [VIPI code repository](https://github.com/EnXan/VIPI). | |
