void HandDetector::drawFaceMarks ( const cv::Mat &  src, cv::Mat &  dst, cv::Scalar  color = cv::Scalar(0, 255, 0), int  thickness = 1  ) Tracks and covers the faces that appear in the image. The faces are covered with a square so they do not interfere with the rest of the segmentation. Parameters: src Original image coming from the video input. dst Output image with the squares over the faces. color Color of the squares, default is black. thickness Thickness of the square drawn over the faces. { //-- Allocate the dst matrix if empty: if ( dst.total() == 0) dst = src.clone(); //-- Plot the bounding rectangles: if ( !lastFacesPos.empty() ) { std::cout << "[Debug] Detected " << lastFacesPos.size() << " face(s)." << std::endl; for ( int i = 0; i < lastFacesPos.size(); i++) cv::rectangle( dst, lastFacesPos[i], color, thickness ); } }
