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。(Proposed based on wavelet transform algorithm can be against geometric attacks.# Watermark embedded in the first part of the host image wavelet decomposition, embedded watermark, and then through the cosine transform of the watermarked image obtained by a feature vector, using the feature vector and the watermark information through 1231 to generate a binary logic function series, the sequence as the key/watermark extraction part is# treated transform measured image, and then obtained through the cosine transform the image of a feature vector under test, using the feature vector and the key function by 1241 to extract the watermark .)
