A Binocular Framework for Face Liveness Verification under Unconstrained Localization

In this paper, we propose a binocular framework for face liveness verification under unconstrained localization. The proposed framework contains two components: the first component localizes imbalanced points in face regions of an input pair of stereo images and the second component detects whether an imaging face is a 2D object or a 3D object. We test the propose framework on a publicly available stereo face database, which demonstrated its potential.
