3d face recognition across pose and expression

... for face alignment, recognition, and synthesis. Blanz and Vetter [Blanz and Vetter, 1999] propose 3D morphable models for 3D faces modeling, which model the variations of both 3D face shape and ... of 3D face processing techniques. It reviews existing 3D face process- ing techniques, including techniques for 3D face geometry modeling, 3D face motion modeling, 3D face motion tracking and ... model-based 3D face tracking, and 3D face synthesis such as text- and speech-driven face animation. 2.3 Geometric-based facial motion modeling, analysis and synthesis Accurate face motion analysis and...
