Enhancing rPPG pulse-signal recovery by facial sampling and PSD Clustering
Biomedical Signal Processing and ControlIn order to increase the accuracy of traditional methods for camera-based pulse rate estimation, we propose a novel systemic approach that extracts multiple remote photoplethysmography (rPPG) signals from a set of scattered facial patches and effectively separates good estimates from noisy ones via a novel unsupervised Power Spectral Density (PSD ...
