Key result
Remote photoplethysmography using skin segmentation in the YCbCr color space achieved a lower heart rate estimation error percentage (5.21%) compared to the traditional RGB color space (8.46%).
Why the study?
Non-contact rPPG heart rate detection is sensitive to subject movement and light variation, causing motion artifacts that challenge accurate physiological signal extraction.
Absolute Event Rate: 5.21% vs 8.46%
Using YCbCr and HSI color spaces with skin segmentation improves the accuracy of remote photoplethysmography for non-contact heart rate detection compared to traditional RGB color space.

May refine rPPG preprocessing for artifact reduction in controlled settings; leaves open clinical validation before practice adoption.
Sheng et al. (2022) studied Heart rate monitoring (n=15). Skin segmentation and rPPG signal extraction in YCbCr color space vs. RGB color space was evaluated on Error percentage of estimated heart rate compared to reference. Remote photoplethysmography using skin segmentation in the YCbCr color space achieved a lower heart rate estimation error percentage (5.21%) compared to the traditional RGB color space (8.46%).
