Hand Motion from 3D Point Trajectories and a Smooth Surface Model

  title={Hand Motion from 3D Point Trajectories and a Smooth Surface Model},
  author={Guillaume Dewaele and Frederic Devernay and Radu Horaud},
A method is proposed to track the full hand motion from 3D points reconstructed using a stereoscopic set of cameras. This approach combines the advantages of methods that use 2D motion (e.g. optical flow), and those that use a 3D reconstruction at each time frame to capture the hand motion. Matching either contours or a 3D reconstruction against a 3D hand model is usually very difficult due to self-occlusions and the locally-cylindrical structure of each phalanx in the model, but our use of 3D… CONTINUE READING
