Abstract: Abstract 3D face recognition has received a lot of attention in the last decade, leading to improved sensors and algorithms that promise to enable large-scale deployment of biometric systems that rely on this modality. This chapter discusses advances in 3D face recognition with respect to current research and technology trends, together with its open challenges. Five real-world scenarios are described for application of 3D face biometrics. Then we provide a comparative overview of the currently available commercial sensors, and point out to research databases acquired with each technology. The algorithmic aspects of 3D face recognition are broadly covered; we inspect automatic landmarking and automatic registration as sine qua non parts of a complete 3D facial biometric system. We summarize major coordinated actions in evaluating 3D face recognition algorithms, and conclude with a case study on a recent and challenging database.
