| 摘 要： | 基于对MPEG-2视频压缩编码标准以及已有的基于DCT变换的视频水印算法的研究,充分考虑到人眼视觉特征,本文提出了一种采用基于DCT系数的自适应视频水印算法。此算法吸取了DCT视频水印算法的优点,然而与其相比却具有更强的不可见性与鲁棒性。

| Abstract: | This paper brought out an adaptive video watermark algorithm based on DCT transform. By researching on MPEG-2 video compression standard and existing DCT video watermark algorithms,we considered of the features of Human Visual System and the advantages of the existing algorithms in this algorithm. During the experiment,it has been proved to be invisible and robust enough,compared with the existing ones. |
