3D Face Recognition: The Ultimate Biometric Lock

Ron Kimmel


Abstract

At the Geometric Image Processing Lab., together with the Bronstein brothers, and with the help of lab engineer E. Gordon, we built a system that can distinguish between two identical twins based on 3D pictures of their faces. Our system can recognize faces under various poses and facial expressions. In this talk I will review the components of our system and some theoretical problems and technical challenges, like flat embedding. The numerical building blocks include:

1. Kimmel, Sethian, "Fast marching on triangulated domains scheme, that efficiently computes geodesic distances on triangulated surfaces"

2. Elad, Kimmel, "Bending invariant signatures for isometric surfaces. A method for matching isometric surfaces"

3. Bronstein, Bronstein, Kimmel, "Eigen-forms for expression invariant 3D face recognition"

Some keywords: Eikonal solvers, geodesic distance maps, Multidimensional scaling, dimensionality reduction, eigen-decomposition/flattening of geometric structures.
