| 摘 要： | 针对MPEG-2标准，提出一种新的盲水印算法，首先使用领域平均的方法，计算载体视频两条I帧DCT变换低频系数均线的交叉点作为嵌入位置，然后利用奇偶量化的方法实现水印信息与同步码的嵌入。实验表明，算法具有较好的不可见性，且针对常规攻击具有较强的鲁棒性。

| Abstract: | A new blind video watermarking algorithm based on MPEG-2 is proposed. First, calculate the inter?section on mean-line in low frequency DCT coefficients between two I frame of carrier video as the embedding position. And then the watermark information and the synchronous code are embedded by using odd-even quanti?zation. The experimental results show that the algorithm is of good invisibility and strength in robustness under the conventional attacks. |
