| 摘 要： | 研究了DCT域变换技术、提出一种基于DCT域颜色分量的数字盲水印算法,该算法将水印信息嵌入到人眼不易识别的蓝色分量中,有效地提高了水印的不可见性,并且通过采用均值嵌入有效地实现了水印的盲提取。实验通过图像整体嵌入水印,有效地抵抗剪切和加噪操作带来的水印丢失问题。

| Abstract: | The thesis researched the region of DCT varied technology, put forward a numberal blind watermarking al- gorithm based on the region of DCT colur component, the algorithm put the watermarking information embed blue compo- nent which the eyes did not distinguish. It effectually improved the invisibility of watermarking and through embed aver- age value to realize the watermarking of the blind abstraction. The experiment was through image to entirely embed water- marking, effectually resisted cutting and problem which losed watermarking bringed by operation of increasing noise. |
