Can Your Face Detector Do Anti-spoofing? Face Presentation Attack Detection with a Multi-Channel Face Detector

Understand

In a typical face recognition pipeline, the task of the face detector is to localize the face region.

• However, the face detector localizes regions that look like a face, irrespective of the liveliness of the face, which makes the entire system susceptible to presentation attacks.
• In this work, we try to reformulate the task of the face detector to detect real faces, thus eliminating the threat of presentation attacks.
• While this task could be challenging with visible spectrum images alone, we leverage the multi-channel information available from off the shelf devices (such as color, depth, and infrared channels) to design a multi-channel face detector.
