# 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.
