  • watermark.rar 通过离散小波变换dwt,实现数字图像水印嵌入与提取。
  • shuiyin.rar 基于DWT及DCT的数字水印的代码,该改代码是分开形式给出,具体结果自己可以运行试试,很不错的
  • dwt-matLab-marking.rar 提出了一种基于小波变换可抗击几何攻击算法。在水印嵌人 部分# 首先对宿主图像进行小波分解 、 嵌人水印, 再通过余弦变换求得该水印图像的一个特征向量, 利用该特征向量和水印 信息通过12 31 函数生成一个二值逻辑系列, 将该序列作为密钥/ 水印提取部分为# 对待测的图像进行小波变换, 再通过余 弦变换求得待测图像的一个特征向量, 利用该特征向量和密钥通过1 2 4 1 函数提取出水印。
