Abstract

Photoplethysmography (PPG) has been widely used in clinical applications for monitoring vital signs especially heart rate by pulse oximeter. Recent researches have demonstrated the possibility of using fingertip video based PPG approach to estimate heart rate by smartphones. However, due to the variation of camera sensor characteristics in difference smartphones, the conventional fixed region-of-interest (ROI) for PPG signal extraction technique is not reliable. In this paper, a novel frame adaptive ROI method is proposed to detour the color saturation or cut-off distortion in the fingertip video capturing process for improving the reliability due to variation and limited dynamic range of the camera sensors in different smartphone models. Experimental results demonstrate that the proposed method can produce good pulsatile waveform and achieve high heart rate estimation accuracy using different smartphone models as compared with a FDA (U.S. Food and Drug Administration) approved commercial pulse oximeter.
