Face presentation attack is a technology using photos, videos and other media to present faces in front of cameras to spoof face recognition systems. Most of the existing face presentation attack detection methods apply depth feature for supervised classification, while ignoring the effective fine-grained information and the correlation between depth information and texture information. Therefore, a texture and depth feature enhancement based two-stream face presentation attack detection method is proposed. One end of the network extracts the facial texture features with a more robust deception texture pattern than the original convolution network through the central differential convolution network. The other end of the network generates the depth information of the depth map through generative adversarial network to improve the robustness to the appearance changes and image quality differences. In the feature enhancement module, a central edge loss is designed to fuse and enhance two types of complementary features. The experimental results on 4 datasets show that the proposed method achieves superior performance in both intra-data set and cross-data set tests. ? 2023 Journal of Pattern Recognition and Artificial Intelligence.
