| # RealDocBench-Layout |
|
|
| A 1,500-page document-layout benchmark for evaluating layout-detection |
| models on real-world documents. COCO-style annotations across **9 block |
| classes**. |
|
|
| ## Contents |
|
|
| - `images/` — 1,500 page images (PNG / JPG / occasional WebP-as-PNG; see Caveats). |
| - `annotations/<pageId>.json` — per-page COCO files, each with a single |
| `image` record, an `annotations` list, a `categories` list, and a |
| `page_info` block. |
| - `manifest.csv` — pageId → domain + source URLs. The canonical row list. |
|
|
| ## Block classes (9) |
|
|
| ``` |
| text, heading, section_heading, header, footer, page_number, |
| figure, table, key_value |
| ``` |
|
|
| | class | what it covers | |
| |---|---| |
| | `text` | body text and other inline content | |
| | `heading` | document title | |
| | `section_heading` | section / subsection titles | |
| | `header` | running page header | |
| | `footer` | running page footer | |
| | `page_number` | page-number indicators | |
| | `figure` | images, diagrams, charts, barcodes, QR codes | |
| | `table` | tabular data | |
| | `key_value` | form fields / key-value pairs | |
|
|
| The companion benchmark loader at |
| [`extend-hq/realdoc-bench`](https://github.com/extend-hq/realdoc-bench) |
| walks each annotation file and produces 9-class block predictions; see |
| `realdoc_bench/layout/normalizers/coco.py`. |
|
