  1. Effect of different 3D Human Representations on BABEL-TAL-20 (BT-20). The 2D features obtained from the rendered videos exhibit inferior performance compared to the 3D joint features. This discrepancy arises from the 3D representation’s ability to encapsulate a richer information set compared to the 2D representation, underscoring the superiority of the 3D approach. mAP mean Average Precision, tIoU threshold IoU.
