OpencvSharp之实现颜色识别

点击提取颜色，比如青色

          {
            Mat c1 = new Mat(path, ImreadModes.AnyColor);
            Mat hsv = new Mat();
            Cv2.CvtColor(c1, hsv, ColorConversionCodes.BGR2HSV);       //转化为HSV

            Mat dst = new Mat();
            Scalar scL = new Scalar(hMin, sMin, vMin);
            Scalar scH = new Scalar(hMax, sMax, vMax);
            Cv2.InRange(hsv, scL, scH, dst);                            //获取HSV处理图片
            var kernel = Cv2.GetStructuringElement(MorphShapes.Rect, new             OpenCvSharp.Size(20, 20),
               new OpenCvSharp.Point(-1, -1));
            Cv2.Threshold(dst, dst, 0, 255, ThresholdTypes.Binary);         //二值化
            Cv2.Dilate(dst, dst, kernel);                                   //膨胀
            Cv2.Erode(dst, dst, kernel);                                    //腐蚀
            }
        Scalar greenScMin = new Scalar(25, 52, 72);   //绿
        Scalar greenScMax = new Scalar(102, 255, 255);
        Scalar yellowScMin = new Scalar(11, 43, 46); // 黄
        Scalar yellowScMax = new Scalar(34, 255, 255);
        Scalar redScMin = new Scalar(0, 43, 46);   //红
        Scalar redScMax = new Scalar(10, 255, 255);
        Scalar blackScMin = new Scalar(0, 0, 0);  // 黑
        Scalar blavkScMax = new Scalar(180, 255, 46);
