Deep Spatial Gradient and Temporal Depth Learning for Face Anti-Spoofing
Deep Spatial Gradient and Temporal Depth Learning for Face Anti-Spoofing
Face anti-spoofing is critical to the security of face recognition systems. Depth supervised learning has been proven as one of the most effective methods for face anti-spoofing. Despite the great success, most previous works still formulate the problem as a single-frame multi-task one by simply augmenting the loss with depth, …
