Figure 5From: Motion artifact removal from photoplethysmographic signals by combining temporally constrained independent component analysis and adaptive filter Statistic performance of cICA-LMS method in comparison with FFT-LMS and MAF methods. It shows the RRMSE (%) changing with SNR (dB) of three different methods. The performance bound of cICA-LMS is also shown using the solid line. (a): Red channel PPG; (b): IR channel PPG.Back to article page
