一种基于DCT的静态图像的数字水印算法

Digital Watermarking Algorithm Based on the Static Image of DCT

随着网络技术、电子商务的发展,对传统的版权保护提出了挑战,作为解决数字产品版权保护新方法数字水印技术,近年来受到极大的关注.本文着重提出一种基于离散余弦变换(DCT)的直流和中频静态图像的数字水印嵌入算法和检测过程.

With the developement of the network technology and electron business affair,the advance challenge for protection of the tradition copyright,as a new method of solving copyright protection of digital productsdigital watermarking technology,has attracted much intereste in recent years based on DCT,this paper emphatically introduce a digital watermarking embedding algorithm and a detecting process of the DC and IF static images.
