Abstract

This invention discloses a remote photoplethysmography measurement system where active appearance model of the face is used to analyze skin color variations for observing human vital signs including, but not limited, average heart rate, heart rate variation and respiratory rate. The invention uses non-invasive, remote, passive sensors, i.e. camera, for the proposed analysis where different color channels and model based facial regions are utilized for extracting the relevant periodic components from the modelled color signal.
