A Study on Measurement of Photoplethysmograph Using a Smartphone Camera

초록

In this study, we proposed a method for measuring photoplethysmographic using a smartphone camera. A development algorithm is consists 6 procedures. The first is to convert RGB to Gray level from a camera image, the second is to detect ROT from image, the third is to extract photoplethysmography signal from a camera image, the fourth is to filter baseline, and the last is to oversample procedure using cubic spline interpolation. The proposed algorithm has been tested using several smartphone with a person and which can effectively acquire person's PPG signal at any situation. We supposed that the proposed algorithm can easily adapt for a smartphone m-health system.
