Asymmetric 3D/2D Processing: A Novel Approach for Face Recognition
Facial image analysis is very useful in many applications such as video compression, talking heads, or biometrics. During the last few years, many algorithms have been proposed in particular for face recognition using classical 2-D images. Face is fairly easy to use and well accepted by people but generally not robust enough to be used in most practical security applications because too sensitive to variations in pose and illumination. One possibility to overcome this limitation is to work in 3-D instead of 2-D. But 3-D is costly and more difficult to manipulate and then ineffective to authenticate people in most contexts. Hence, to solve this problem, we propose a novel face recognition approach that is based on an asymmetric protocol: enrolment in 3-D but identification performed from 2-D images. So that, the goal is to make more robust face recognition while keeping the system practical. To make this 3-D/2D approach possible, we introduce geometric invariants used in computer vision...
