Dual-Bridging With Adversarial Noise Generation for Domain Adaptive rPPG Estimation

Jingda Du, Si-Qi Liu, Bochao Zhang, Pong C. Yuen

CVPR 2023poster

The remote photoplethysmography (rPPG) technique can estimate pulse-related metrics (e.g. heart rate and respiratory rate) from facial videos and has a high potential for health monitoring. The latest deep rPPG methods can model in-distribution noise due to head motion, video compression, etc., and…

Remote Photoplethysmography Correspondence Feature for 3D Mask Face Presentation Attack Detection

Si-Qi Liu, Xiangyuan Lan, Pong C. Yuen

ECCV 2018poster

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 rPPG-based methods achieve promisin…
