This is a simple JavaScript implementation of rPPG, a way to measure the pulse rate without skin contact. It uses a live feed of the face to analyse subtle changes in skin color.
Here's how it works:
- The face is detected and continuously tracked
- Signal series is obtained by determining the facial color in every frame
- Heart rate is estimated using frequency analysis and filtering of the series
If you are interested in the specifics, feel free to have a read of my publications on the topic:

Currently, tracking is disabled. Works best if there is no subject motion.
