用matlab写的图像离散余弦变换域的水印嵌入与提取以及攻击测试代码，稍加修改就可以移植到自己的程序中，很有用哦(Matlab write images using discrete cosine transform domain watermark embedding and extraction as well as attacks on the test code, slightly modified can be transplanted to their own program, very useful Oh)

这是关于数字水印的嵌入例程！经过调试，可以放心使用！(This is on the digital watermark embedded routines! After debugging, can be assured use!)
