HaWoR: World-Space Hand Motion Reconstruction from Egocentric Videos

Hand and camera motion in world space

Figure 1. We propose HaWoR, a world-space 3D hand motion estimation method for egocentric videos. We decouple world-space hand motion estimation by combining camera-frame motions and world-space camera trajectories. HaWoR achieves state-of-the-art performance on both camera pose estimation and hand motion reconstruction, even under challenging cases where hands are out of the view frustum.
