WAVELET-BASED rPPG SIGNAL ANALYSIS: CWT FOR SPECTRAL PEAK LOCALIZATION AND IDENTIFICATION WITH PULSE OXIMETER VALIDATION
Remote photoplethysmography (rPPG) has become a promising non-contact technology for cardiovascular monitoring, but the accuracy of spectral peak detection remains unpredictable due to motion artifacts, noise, and camera signal quality. Traditional methods often fail to localize and identify heart rate peaks in the presence of such disturbances.
