Detecting 3D mask attacks to a face recognition system is challenging. Although genuine faces and masks show significantly different remote photoplethysmography (rPPG) signals, rPPG-based anti-spoofing methods often suffer from performance degradation due unstable alignment in the video sequence weak rPPG signals. To enhance signal motion-robust way, landmark-anchored stitching method proposed ...

This paper considers two important problems for autonomous robot navigation in a dynamic environment, where the goal is to predict pedestrian motion and control a robot with the prediction for safe navigation. While there are several methods for predicting the motion of a pedestrian and controlling a robot to avoid incoming pedestrians, it is still difficult to safely navigate in a dynamic envi...
