BABEL is a large dataset with language labels describing the actions being performed in mocap sequences. BABEL labels about 43 hours of mocap sequences from AMASS [1] with action labels. Sequences have action labels at two possible levels of abstraction:
- Sequence labels which describe the overall action in the sequence
- Frame labels which describe all actions in every frame of the sequence. Each frame label is precisely aligned with the duration of the corresponding action in the mocap sequence, and multiple actions can overlap.
To download the BABEL action labels, visit our 'Data' page. You can download the mocap sequences from AMASS.
Tutorials
We release some helper code in Jupyter notebooks to load the BABEL dataset, visualize mocap sequences and their action labels, search BABEL for sequences containing specific actions, etc.
See notebooks/ for more details.
Action Recognition
We provide features, training and inference code, and pre-trained checkpoints for 3D skeleton-based action recognition.
Please see action_recognition/ for more details.
Acknowledgements
The notebooks in this repo are inspired by the those provided by AMASS. The Action Recognition code is based on the 2s-AGCN implementation.
