Overview
Recent studies show that subtle changes in a human’s face color due to their heartbeat can be captured by digital cameras. Most existing work focuses on still/rest cases or those with relatively small motions.Researchers at the University of Maryland have created a heart-rate monitoring method using facial video. The method consists of a highly precise motion compensation scheme with optical flow and the use of motion information to adaptively remove ambiguous frequency components to improve the heart rate estimates. This system extracts from a face video a 1-D sinusoid-like face color signal that has the same frequency as the heartbeat.
Applications
