Qualitative study on 3D face databases: A review

Abstract

Recent researches in three-dimensional (3D) face recognition area have proved that, 3D face recognition methods, achieve better accuracy than its 2D counterpart. One of the main advantages of 3D face recognition methods is that it measures the geometry of rigid features on the human face, due to which it becomes an invariant to illumination, expressions and rotations of head (pose variation). But the main drawback of 3D face recognition methods is the acquisition of 3D face images which generally needs a range camera. It is where the research community is facing difficulty. Research in 3D face recognition also depends on available databases. In this paper, we present a qualitative review of all the available 3D face databases. A comparative table of all the databases is also given at the end with all the necessary parameters.
