Novel method for extracting spatio-temporal structure of blood volume pulse for accurate heart rate estimation

Caption

Researchers from TUS propose a method that involves constructing a chrominance matrix using time-series signals from facial patches in an RGB facial video, followed by spatio-temporal structure analysis of blood volume pulse (BVP) using physics-informed DMD in a time-delay coordinate system. Further, heart rate estimation in the time domain is done using beat-to-beat peak period analysis of the extracted BVP signal.
