HORA-DB/Human_motion

Human whole body or hand movements

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.
