Dyn-HaMR: Recovering 4D Interacting Hand Motion from a Dynamic Camera

Input video Dyn-HaMR (Ours) HaMeR Camera motion Hand motion Figure 1. Dyn-HaMR as a remedy for the motion entanglement in the wild. The green and red arrows represent the direction of the hand motion. Dyn-HaMR (Ours) can disentangle the camera and object poses to recover the 4D global hand motion in the real world whilst state-of-the-art 3D hand reconstruction methods like HaMeR [37], IntagHand [25] and ACR [51] fail to do so since they cannot disentangle the sources of motion.
