| # EgoInfinity Dataset |
|
|
| Derivative scene assets for a curated subset of [Action100M] (Meta FAIR) |
| clips. Used as the data backend for the |
| [EgoInfinity Browser](https://huggingface.co/spaces/Rice-RobotPI-Lab/egoinfinity) |
| Space. |

| `<clip_id>` is `<youtube_video_id>_<start_sec>_<end_sec>`. The only original |
| YouTube pixels that appear in this repository are inside the SAM-tracked |
| object region of `mask.mp4` (everything outside the mask is painted black); |
| no full source frames are redistributed. |

| ### Attribution |
|
|
| - **Source clips** are from [Action100M] (Meta FAIR). Full source videos |
| remain on YouTube; only the SAM-tracked region appears in `mask.mp4` as |
| a per-frame cutout. |
| - **Depth maps** were generated using MoGe-2. |
| - **Optical flow** was computed using MEMFOF. |
| - **Object segmentation** uses Meta SAM-3 / SAM-3D. |
| - **Hand parameters** were estimated using a WiLoR-based pipeline. Vertex |
| positions are baked from the MANO model (Romero et al., 2017); MANO weights |
| are not redistributed. |
