提出一种基于多值序列模运算的新的变换域公开水印算法,将图像的特征序列量化成可忍受的极限能量多值水印信号随机嵌入到图像的DCT、DWT混合变换域中,通过对特征序列量化结果和提取水印的相关性进行统计,得出水印判定结果。
A novel publishable blended transform domain watermarking algorithm was proposed. A acceptable high-point energy signal was embedded in the blended transform domain of DWT and DCT, then the relation of the original watermark and the extracted watermark was analyzed, and a result of watermarking was get.
