Nettet4. jun. 2024 · State-of-the-art spoof detection methods tend to overfit to the spoof types seen during training and fail to generalize to unknown spoof types. Given that face anti-spoofing is inherently a local task, we propose a face anti-spoofing framework, namely Self-Supervised Regional Fully Convolutional Network (SSR-FCN), that is trained to …
NettetIn order to learn the spoof cues, we propose a residual learning framework that consists of a spoof cue generator and an auxiliary classifier. In the spoof cue generator, we impose the regression loss on the live samples while put no explicit supervision on the spoof samples, which guarantees the spoof cues’ generalization capability. c++ allocate new arrayNettetLearning Generalized Spoof Cues for Face Anti-spoofing. vis-var/lgsc-for-fas • • 8 May 2024.
