- Abstract:
-
Face recognition is one of the most widely applied biometric identification technologies, in which face liveness detection aiming to determine whether a face is genuine or fake, is used to help face recognition systems defend against replay and print attacks, and thus ensure system security. Considering safety and economy, binocular camera based face liveness detection is most commonly adopted at present. However, due to significant variations in lighting conditions of different scenes as well as face poses, the captured face images are often of low quality, which greatly harms the performance of face liveness detection. In this paper, we propose a binocular camera based face liveness detection algorithm, which improves detection performance through optimizing scene illumination recognition. In particular, the proposed algorithm uses the cascaded PID algorithm to adjust the light sensitivity and light supplement of the camera subject to specific lighting and pose angles. It also modifies the photometric range to be within the face area in the case of backlight to ensure effectiveness of the light exposure and supplement control strategy. Extensive experiments have been conducted and the results show that the proposed model outperforms other methods by around 30% in accuracy in complex scenes, with ensured generalizability to diverse application scenes.
