Comparison of proposed RGB signal reconstruction method with conventional green trace method on HR measurement.

HR	RMSE	Bland–Altman	Pearson Correlation
RGB signal reconstruction and MUSIC	5.93	The 95% limits of agreement -10.4 to 12.6 bpm ($\sigma =5.85$)	0.87
Green trace alone and FFT	15.30	The 95% limits of agreement -23.5 to 33.4 bpm ($\sigma =14.5$)	0.48
