This dataset comprises SMPL-H body motion sequences reconstructed from third-person videos, as well as MANO hand motion sequences derived from ego-centric videos.
## Data-format
- whole_body:
- "seq_name"/"file_name".npz
- pose_body: (T, 63)
- betas: (B)
- root_orient: (T, 3)
- trans: (T, 3)
- "other parameters"
- ego_hand:
- Sample ego-centric hand motion clips.
- Each sample has one `.hdf5` annotation file and one same-name `.mp4` source video.
- The `.hdf5` file contains camera intrinsics, camera transforms, hand/body transforms, and hand confidence values.
- Example pair:
- `ego_hand/95125_30577_34946.hdf5`
- `ego_hand/95125_30577_34946.mp4`
## Usage
- whole_body
- usage pip to install smplx, and use smplx.SMPLH to convert parameters into human mesh/joints
- The converted human body mesh uses the negative Y-axis as the gravity axis.
- ego_hand
- Keep the same-name `.hdf5` and `.mp4` files in one directory.
- They can be visualized with the EgoDex 2D visualization script.
