Anti-motion imaging photoplethysmography via self-adaptive multi-ROI tracking and selection.

The imaging photoplethysmography (IPPG) technique allows people to measure heart rate (HR) from face videos. However, motion artifacts caused by rigid head movements and nonrigid facial muscular movements are one of the key challenges.This paper proposes a self-adaptive region of interest (ROI) pre-tracking and signal selection method to resist motion artifacts.
