Heart rate measurement is important for monitoring people's physiological and body state. A method of measuring heart rate using a low-cost Webcam is proposed. The signal containing heartbeat information is extracted from face image sequences according to Photoplethysmography(PPG)principle. Blood Volume Pulse(BVP)is acquired by wavelet filtering followed by energy spectrum analysis utilized to calculate the Heart Rate(HR). Experimental results indicate that this method has a high accuracy which can meet the...
