Figure 2
Bland-Altman plots comparing the values obtained for physiological parameters of interest using the presented methods to values obtained using a contact reference method in nighttime and daytime, respectively.
The solid horizontal line indicates the mean for the data set; the dotted lines indicate the mean ±1.96 standard deviations. (A) HR of the subject imaged in night conditions. (B) RR of the subject imaged in night conditions. (C) HR of the subject imaged in daytime. (D) RR of the subject imaged in daytime.
