FIGURE 8. — Bland-Altman plots comparing accuracy of HR and RR obtained from a iPPG using a face video, with standard approaches for measuring HR (Panel A and B) and RR (Panel C and D). Panel A shows results for HR computed using Hue (0–0.1), compared with HR measured using pulse oximetry. Panel B shows results for HR computed using Green channel, compared with HR measured using pulse oximetry. Panel C shows results for RR computed using Hue (0–0.1), compared with RR measured using self reporting. Panel D shows results for RR computed using Green Channel, compared with RR measured using self reporting. In each set of data their are 5 subgroups based on skin types, Caucasian male (Triangle Up Fill), Caucasian female (Triangle Up), African male (Triangle Down Fill), African female (Triangle Down) and Indian Male (Empty Box).
