Remote Photo Plethysmography (rPPG)

Remote photoplethysmography (rPPG) is a non-contact method for measuring heart rate and other cardiovascular parameters by analyzing subtle color changes in the skin, typically facial. This technique leverages the fact that blood flow causes variations in skin color, which can be detected and analyzed to extract physiological information.

Ballistocardiography (BCG) signals, which is the subtle head motions caused by cardiovascular circulation.
