Revisiting Pixel-Wise Supervision for Face Anti-Spoofing
IEEE Transactions on Biometrics, Behavior, and Identity Science(2021)
摘要
Face anti-spoofing (FAS) plays a vital role in securing face recognition systems from the presentation attacks (PAs). As more and more realistic PAs with novel types spring up, it is necessary to develop robust algorithms for detecting unknown attacks even in unseen scenarios. However, deep models supervised by traditional binary loss (e.g., ‘0’ for bonafide vs. ‘1’ for PAs) are weak in describing...
