%基于DCT的水印算法
%数字水印处理系统主要由水印嵌入和水印检测两个过程。
%水印嵌入过程为:数字水印(X)、原图像(I)和密钥/公钥(K)通过数字水印嵌入算法形成嵌入水印后的图像(I*)。
%水印检测过程为:数字水印(X)、水印图像(I*)和密钥/公钥(K)通过数字水印检测算法检测出数字水印或有无水印。
%基于DCT变换的水印算法:将一个随机序列作为水印信号嵌入到图像DCT变换重要分量的幅度成分中(幅值较大的n个系数作为重要分量)。
%定义一个相似函数来检验水印提取是否成功。试验结果表明,该算法具有不可见性,对通常的图像处理,如剪切、缩放、中值滤波、压缩等
%以及噪声干扰都具有一定的鲁棒性。(err)
