| 摘 要： | 为了对数字视频进行版权保护,结合离散余弦变换和数字视频的相关理论,提出了一种基于帧DCT变换的鲁棒视频水印算法.先对水印进行预处理,然后选择嵌入强度,将水印信息多次重复嵌入到视频帧分块DCT变换的中频系数中.提取水印时无须原始视频的参与.实验结果表明,该算法具有较好的不可见性和较强的鲁棒性.

| Abstract: | In order to protect the copyright of digital video, combined with the discrete cosine transform (DCT) and digital video related theory, a robust video watermarking algorithm based on frame DCT is proposed. Firstly, the values of watermarking were preprocessed. Then after selected the embedding strength, watermarking information was embedded into the blocking DCT intermediate frequency coefficients of video frames repeatedly. Watermarking could be extracted without the original video. Experimental results demonstrate the invisibility and robustness of this algorithm. |
