This paper presents an effective 3D face keypoint detection, description and matching framework based on three principle curvature measures. These measures give a unified definition of principle curvatures for both smooth and discrete surfaces. They

International audience; —2D face analysis techniques, such as face landmarking, face recognition and face verification, are reasonably dependent on illumination conditions which are usually uncontrolled and unpredictable in the real world. The curr

3D face recognition with asymptotic cones based principal curvatures

Autor: Xiang Sun, Yunhong Wang, Liming Chen, Jean-Marie Morvan, Yinhang Tang, Di Huang

Publikováno v: ICB

The classical curvatures of smooth surfaces (Gaussian, mean and principal curvatures) have been widely used in 3D face recognition (FR). However, facial surfaces resulting from 3D sensors are discrete meshes. In this paper, we present a general frame
