3D Face Recognition

The past decades have witnessed the tremendous efforts made on Face Analysis (FA). In spite of great progress achieved so far within the field [1–5], faces recorded by 2D images (or videos) are still not reliable enough as a biometric trait, especially in the presence of illumination and pose changes. With the rapid development in 3D imaging systems, 3D (or 2.5D) scans have been expected as a major alternative to deal with the unsolved issues.
