On the other hand,optimal color space can be used to improve the accuracy of heart rate measurement accuracy of the color space.The experimental results show that the heart rate measurement with RGB color space has the smallest error compared with the heart rate obtained by electrocardiograph(ECG) at the same time.The average error of experiment is 1.68 bpm.Thus,choosing RGB color in non-contact heart rate measurement space can get higher accuracy.
