我应该修改这个图像比较代码,以突出显示/指出两个图像之间的差异.有没有办法修改此代码,以突出显示图像的差异.如果没有任何关于如何去做的建议将不胜感激.

 int width1 = img1.getWidth(null);
            int width2 = img2.getWidth(null);
            int height1 = img1.getHeight(null);
            int height2 = img2.getHeight(null);
            if ((width1 != width2) || (height1 != height2)) {
                System.err.println("Error: Images dimensions mismatch");
                System.exit(1);
            }
            long diff = 0;
            for (int i = 0; i < height1; i++) {
                for (int j = 0; j < width1; j++) {
                    int rgb1 = img1.getRGB(j, i);
                    int rgb2 = img2.getRGB(j, i);
                    int r1 = (rgb1 >> 16) & 0xff;
                    int g1 = (rgb1 >> 8) …
