The separation effect of the same data from Fig. 4 by using SOBI based on dual ROI: a shows subject’s low-quality video and the dual ROI, then b displays 6-channels observations; c displays the source signals separated by using 6-channels SOBI; after filters out residual noises, d obtains the target signals (note: the purple and green column on spectrum respectively denote RR band and HR band)
