## 2D Features for SegDINO3D

We provide pre-extracted 2D features for:

- ScanNet (1513 scenes, 4539 `.pth` files)
- ScanNet200 (1513 scenes, 4539 `.pth` files)

Each scene contains:
- `{scene_id}.pth`
- `{scene_id}_query_3dctr.pth`
- `{scene_id}_query_feats.pth`

All features are stored under:
`data/features_2d/{scannet, scannet200}/`
