Summary

This chapter discusses the state of the art in 3D surface features for the recognition of the human face. Particular emphasis is laid on the most prominent and recent contributions. Features extracted from 3D facial surfaces serve as a means for dimensionality reduction of surface data, facilitating the task of face recognition. The chapter first covers (1) the primary 3D surface representations from which feature representations of surfaces are extracted, (2) rigid transformations and decimation of 3D surfaces, and (3) geometries and topologies of the human face that might influence 3D face recognition. A section first discusses the concepts and mathematical definitions of 3D curvatures and then covers some practical methods for their extraction. The other sections in the chapter focus on 3D segmentation approaches that are specific to facial surfaces, the most prominent rigid approaches to feature extraction, and deformation modeling of 3D face surface.
