Face Anti-Spoofing简记2-GFA-CNN

Face Anti-Spoofing简记2-Learning Generalizable and Identity-Discriminative Representations for Face Anti-Spoofing

创新点

  1. Total Pairwise Confusion (TPC) loss
  2. GFA-CNN

最后

TPC loss不是很理解。作者说:balance the contribution of each spoof pattern, preventing the PA representations from overfitting to dataset-specific spoof patterns.
