| 摘 要： | 本文提出了一种基于Turbo码的DWT域与离散DCT域相结合的视频水印算法. 在该算法中, 先选取视频序列中的关键帧，并对其亮度分量进行一级DWT变换，再对DWT域的逼近子带进行4?的DCT变换，最后在DCT变换的直流系数中嵌入经过伪随机排序和Turbo码编码置乱后的水印信息. 实验结果表明：该算法不仅具有良好的不可见性，而且对各种常见的攻击都具有较好的鲁棒性.

| Abstract: | Abstract: A video watermarking algorithm based on Turbo codes in the DWT-DCT domain is proposed. Firstly, the luminance component of the key frames is decomposed by a DWT transform. Then the approximation sub-band in DWT domain is decomposed by 4? DCT transform. Finally, the watermark information which is sorted by the pseudo-random and encoded by Turbo codes is embedded into the DCT domain. The experimental results demonstrated that the algorithm not only has invisibility, but also has better robustness to a variety of common attacks. |
