The separation and RS automatic selections results on a random low SNR data: a shows a segment of 6-channel R/G/B signals with low SNR, then separated by 6-channels SOBI, b displays the source signals, after filters out residual noises, c obtains the target signals. By kurtosis-based method, the RS (Ch3) was detected accurately, with estimated RR being approximate to reference value from commercial sensor
