Improving the Accuracy of Camera-Based Heart Rate Measurement
ZHU Xian-feng, JIAO Bin, ZHAO Jing, LI Gang, and LIN Ling
The heart rate (HR) measurements based on the camera (visible light) can be used to detect HR in non-contact mode, which has great application prospects both in the clinical application and home health care. However, CMOS sensors equipped with “rolling shutters”, which distinguishes different lines per frame to become
