MANUS-DexYCB Annotation Format

Each WebDataset sample contains a .json metadata member plus the available multimodal files for that sample.

}

Modalities

  • full_rgb.png: original full-scene RGB image converted to PNG.
  • full_depth.png: full-scene depth map.
  • hand_rgb.png: hand-region RGB crop.
  • hand_depth.png: hand-region depth crop.
  • hand_bbox.json: hand-region bounding box for the RGB crop.
  • hand_depth_bbox.json: hand-region bounding box for the depth crop.
  • vertices.json: local hand mesh vertices and merged bounding-box metadata.
  • mesh_front.png, mesh_back.png, mesh_left.png, mesh_right.png, mesh_top.png, mesh_bottom.png: six canonical rendered mesh views.
  • six_view_bbox_*.json: bounding boxes for canonical rendered mesh views.
  • extra_view_image_primary.png, extra_view_image_complementary.png: selected primary/complementary projection views.
  • extra_view_bbox_primary.json, extra_view_bbox_complementary.json: bounding boxes for selected projection views.

Not every future MANUS subset will expose the same modality set; check available_files and the manifest for each sample.
