Keywords Face spoof attack detection Multiple-feature learning Capsule neural networks Hypergraph regularization A B S T R A C T Face authentication has been widely used in personal identification. However, face authentication systems can be attacked by fake images. Existing methods try to detect such attacks with different features. Among them, using color images become popular since it is flexible and generic. In this paper, a novel feature representation for face spoof attack detection,

To achieve it, capsule neural networks are used to integrate different types of features. In addition, hypergraph regularization is applied to learn the correlations among samples. In this way, the descriptive power is improved. The proposed feature representation is compared with existing features for face spoof attack detection and experimental results on two commonly used datasets emphasize the effectiveness of HGC-CNN.
