The 4-Source Photometric Stereo Under General Unknown Lighting
Many previous works on photometric stereo have shown how to recover the shape and reflectance properties of an object using multiple images taken under a fixed viewpoint and variab...

3D Rigid Facial Motion Estimation from Disparity Maps
This paper proposes an approach to estimate 3D rigid facial motions through a stereo image sequence. The approach uses a disparity space as the main space in order to represent all...
