Non-contact Heart Rate Measurement Based on Facial Video Taken by RGB Cameras and Its Applications

Abstract

We live under various stresses every day. Serious stress can have adverse effects on the body and mind and must be addressed before it leads to major illness or accidents. Therefore, in this paper, we realized by a normal RGB camera to extract hemoglobin pigment and shadow component from the RGB image of the skin, and the separated hemoglobin pigment component video is used as the pulse wave. Since the shadow component is also separated, robust measurement of lighting fluctuations (change in shadow component) is realized. This method can be used in practical scenes indoors and outdoors.
