Face morphing attack detection based on high-frequency features and progressive enhancement learning
Publikováno v:
Frontiers in Neurorobotics, Vol 17 (2023)
Face morphing attacks have become increasingly complex, and existing methods exhibit certain limitations in capturing fine-grained texture and detail changes. To overcome these limitation, in this study, a detection method based on high-frequency fea
