A Motion Dataset Filled In Missing Human Meshes
Ego-Exo4D-HM adds dense 4D human reconstructions to synchronized first- and third-person video.
Summary
Ego-Exo4D-HM adds dense 4D human reconstructions to synchronized first- and third-person video.
The original Ego-Exo4D collection provides synchronized egocentric and multi-view exocentric captures but only sparse 3D human-pose annotations. The new release supplies reconstructed human meshes and the accompanying pipeline, creating denser motion data for skill learning, assessment and embodied-AI research. The paper announces a dataset and reconstruction method; it does not claim that every pose, body surface or occluded movement is ground truth.
