# 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.
[Action100M]: https://github.com/facebookresearch/Action100M

`<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.
## License
This dataset is released under the FAIR Noncommercial Research License v1
(see [LICENSE-Action100M](LICENSE-Action100M)) for **noncommercial research
use only**. Per Section 1.b.ii, redistribution must include a copy of this
license file.
### 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.
