Remote Photoplethysmography Correspondence
Feature for 3D Mask Face Presentation Attack
Detection
Abstract. 3D mask face presentation attack, as a new challenge in face
recognition, has been attracting increasing attention. Recently, remote
Photoplethysmography (rPPG) is employed as an intrinsic liveness cue
which is independent of the mask appearance. Although existing rPPGbased methods achieve promising results on both intra and cross dataset
scenarios, they may not be robust enough when rPPG signals are contaminated by noise. In this paper, we propose a new liveness feature,
called rPPG correspondence feature (CFrPPG) to precisely identify the
heartbeat vestige from the observed noisy rPPG signals. To further overcome the global interferences, we propose a novel learning strategy which
incorporates the global noise within the CFrPPG feature. Extensive experiments indicate that the proposed feature not only outperforms the
state-of-the-art rPPG based methods on 3D mask attacks but also be
able to handle the practical scenarios with dim light and camera motion.
