    这个程序再matlab2012b版本上调试成功,以前在毕业设计的时候在网上找到的资料,希望对大家有用,数字水印算法实现(matlab程序包),包含有DCT水印嵌入算法,DWT水印嵌入算法,以及水印攻击和性能测试程序。参考价值极大(This program debug version then matlab2012b success in graduate design information previously found on the Internet when we want to be useful, a digital watermarking algorithm (matlab package), including a watermark embedded DCT algorithm, DWT algorithm embedded watermark, watermark attack and performance testing procedures. Great value)
