Heart rate estimation in intense exercise videos

2022 IEEE International Conference on Image Processing (ICIP), 2022
Estimating heart rate from video allows non-contact health monitoring with applications in patient care, human interaction, and sports. Existing work can robustly measure heart rate under some degree of motion by face tracking. However, this is not always possible in unconstrained settings, as the face might be occluded or even outside the camera. Here,

Non-Contact Heart Rate Monitoring Based on Millimeter Wave Radar

IEEE Access, 2022
Millimeter Wave(mmWave) radar has been widely used in vital sign monitoring with non-contact and privacy protection. To reduce the effect of random body motion, respiration, and its harmonics on heart rate estimation, the heart rate monitoring based on ...
