摘要
文章提出了一种DCT域内分形数字水印方法。首先介绍了该水印的设计方案,然后详细探讨了该算法的实现过程,最后利用试验对该方法进行了论证。试验结果表明,该方法具有很好的鲁棒性和不可见性,简单易行,操作性强。
The paper brings forward a fractal watermarking method in DCT domain.Firstly,it introduces the design scheme of the watermarking.Secondly,it discusses the process of this method at length.At last,it demonstrates this method is right by some tests.These tests prove the method is robust ,simple ,easy to use.
