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 walks each annotation file and produces 9-class block predictions; see realdoc_bench/layout/normalizers/coco.py.
