MotionCrafter reconstructs 4D geometry and motion from monocular video using a 4D VAE

advanced Published 31 Mar 2026
Action Steps
  1. Jointly reconstruct 4D geometry and estimate dense motion from a monocular video
  2. Represent dense 3D point maps and 3D scene flows in a shared coordinate system
  3. Utilize a 4D VAE to learn the joint representation effectively
  4. Apply the learned representation to various applications such as robotics, autonomous driving, and animation
