摘要
结合DCT水印具有较好的鲁棒性、通用性的特点,讨论了DCT水印的基本原理与算法,目前常见的一些算法和他们之间的差别。然后,给出了一种DCT水印的实现方法和其JAVA下的描述算法。最后,通过比较被攻击后的水印,结果证明该方法是有效的。
Combining with the characteristics of better robustuess and generality of DCT watermark,this article discuses its basic priciple and common algorithms and differences between them,then gives a method to implement DCT watermark and its descriptive algorithm under JAVA.At last,the attacked watermark is compared,the result indicated that the method is effective.
