| # MANUS-DexYCB Annotation Format |
|
|
| Each WebDataset sample contains a `.json` metadata member plus the available multimodal files for that sample. |
|
|
| ## Per-Sample JSON Fields |
|
|
| ```json |
| { |
| "manus_sample_id": "dexycb_test_000001_processed_000001", |
| "config": "dexycb", |
| "split": "test", |
| "source_dataset": "DexYCB", |
| "source_version": "DexYCB", |
| "source_split": "test", |
| "source_image_id": "000001_processed_000001", |
| "source_license_id": "cc-by-nc-4.0", |
| "source_license_name": "Creative Commons Attribution-NonCommercial 4.0 International", |
| "contains_source_pixels": true, |
| "processing_pipeline_version": "manus-dexycb-v1.0", |
| "available_files": ["full_rgb", "full_depth", "hand_rgb", "hand_depth", "vertices", "mesh_front"] |
| } |
| ``` |
|
|
| ## 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. |
