Abstract
The present disclosure discloses a device for efficiently extracting adaptively selected contactless multi-player heart rates includes: an acquisition module that covers a court to obtain videos from a plurality of angles during players training; a valid player obtaining module configured to remove players with low contributions to training and games in the videos; a facial ROI extraction module configured to detect whether the facial ROIs of valid players contain perfect eye region features, and use the facial ROIs containing the eye region features as best facial ROIs for heart rate extraction; and an analysis and estimation module configured to analyze the detected best facial ROIs by using blind source separation, and estimate a RGB signal by a JADE algorithm to obtain the heart rate values of the valid players.
