Comparisons of Heart rate estimation algorithms

Algorithm	HR Signal	Computation	STI
[9] [2]	Average Intensity	Real Time	YES
[6]	Green Channel	Real Time	YES
[7] [8]	ICA(R,G,B)	Requires ICA	Not Mentioned
Proposed	$log \frac{{\bar{P}}_{R}^{i} {\bar{P}}_{G}^{i - 1}}{{\bar{P}}_{G}^{i} {\bar{P}}_{R}^{i - 1}}$	Real Time	Theoretically Not

STI: Sensitive to Illumination
