Face Liveness Detection Using Thermal Face-CNN with External Knowledge [PDF]
Symmetry, 2019 Face liveness detection is important for ensuring security. However, because faces are shown in photographs or on a display, it is difficult to detect the real face using the features of the face shape. In this paper, we propose a thermal face-convolutional neural network (Thermal Face-CNN) that knows the external knowledge regarding the fact that the ...
