Shape of Motion presents a method for 4D reconstruction of dynamic scenes from a single monocular video by leveraging SE(3) motion bases and data-driven priors like monocular depth maps and long-range 2D tracks. The method showcases state-of-the-art results in 3D/2D motion estimation and novel view synthesis for dynamic scenes, although it faces challenges such as fast motion and occlusions.
