void HandDetector::threshold ( const cv::Mat &  src, cv::Mat &  dst  ) [private] Thresholds the input image using the HSV range. Parameters: src Input image dst Binary output image { //-- Convert to HSV cv::Mat hsv; cv::cvtColor( src, hsv, CV_BGR2HSV); //-- Threshold cv::inRange(hsv, lower_limit, upper_limit, dst); //-- If color limit is arround 0, hue channel needs to be inverted if (hue_invert) { std::vector< cv::Mat > hsv; cv::split( dst, hsv); cv::bitwise_not( hsv[0], hsv[0] ); } }
