DocLayout-YOLO — ONNX with dynamic axes

Re-export of juliozhao/DocLayout-YOLO-DocStructBench and the DocLayNet-pretrained variant to ONNX with dynamic batch + spatial dimensions, which the upstream releases do not provide.

Why dynamic axes?

The official DocLayout-YOLO ONNX exports use fixed input shapes (e.g. 1024×1024). Dynamic axes let downstream tools batch arbitrary page sizes without re-exporting per resolution — convenient for desktop OCR pipelines that hit pages of mixed DPI.

Variants

Subdir	Source	Use case
doclayout_yolo_onnx_dynamic/	DocStructBench (academic + business mix)	Primary — used by ScanIndex layout_analyzer
doclayout_yolo_doclaynet_onnx_dynamic/	DocLayNet (annotated diverse docs)	Auxiliary for non-table region routing

Each subdir contains the .onnx + .onnx.data (external weights) + a .names.json for class id → label mapping.
