    public static void m3() {
        URL url = ClassLoader.getSystemResource("lib/opencv_java440.dll");
        System.out.println("url.getPath() ===== " + url.getPath());
        System.load(url.getPath());

        System.out.println("Welcome to OpenCV " + Core.VERSION);
        Mat m = new Mat(5, 10, CvType.CV_8UC1, new Scalar(0));
        System.out.println("OpenCV Mat: " + m);
        Mat mr1 = m.row(1);
        mr1.setTo(new Scalar(1));
        Mat mc5 = m.col(5);
        mc5.setTo(new Scalar(5));
        System.out.println("OpenCV Mat data:
" + m.dump());
