In the camera-based remote PPG (rPPG) monitoring, the region of interest (ROI) is related to the signal quality and the computational load for the signal extraction processing.

Designating the best ROI on the body while minimizing its size is essential for computationally efficient rPPG extraction.  In this study, we densely analyzed the face region to find the computationally efficient ROI for facial rPPG extraction.
