DRIFT, NOISE, AND MOTION ARTIFACT CORRECTION METHOD FOR PHOTOPLETHYSMOGRAM (PPG) SIGNALS AND SYSTEM THEREOF

摘要

The present disclosure relates to a method and system for processing a photoplethysmogram (PPG) signal to improve accuracy of measurement of physiological parameters of a subject. The method may include removing a baseline drift from the PPG signal; obtaining a drift removed signal; filtering the drift removed signal; obtaining a filtered signal; performing motion artifact correction on the filtered signal; and obtaining a corrected signal.
