Remote photoplethysmography measures heart rate of a person without any contact, from their video. This is an implementation of rPPG called as Plane Orthogonal-to-Skin (POS) as described in the IEEE paper - "Algorithmic Principles of Remote PPG," W. Wang, A. C. den Brinker, S. Stuijk and G. de Haan.
hi,Thank you for your sharing. I am very sorry to trouble you.The heart rate I get when I use the camera is not accurate.How to determine framerate?I'm using framerate=camera.get(cv2.cap_prop_fps) to get the framerate. And different videos get the same heart rate. Can you give some suggestions?
