        return -1;
    }

    //显示图片
    namedWindow("load image", CV_WINDOW_AUTOSIZE);

    //修改图片
    namedWindow("alter image", CV_WINDOW_AUTOSIZE);

    cvtColor(src, output_image, CV_BGR2GRAY);
    imshow("alter image", output_image);

    //保存修改完的图片
    imwrite("C:/Users/Administrator/Desktop/2.jpg", output_image);

    //等待任意键按下
