| 摘 要： | 稳健的视频水印算法对数字视频产品的版权保护具有重要意义。在先前提出的脆弱数字水印算法的基础上,通过采用自适应策略对视频序列中的不同图片根据其特点采用不同的嵌入算法,使得水印的嵌入对视频码流的改动最小,同时结合纠错编码技术,给出了一种较为稳健且简单、快速的视频数字水印算法。经仿真测试后,实验结果显示提出的视频水印新算法具有较强的抗二次编码攻击和噪声污染的能力,具有较好的稳健性。 |

| Abstract: | Robust video watermarking algorithm is very important for copyright protection of digital video contents.In this paper,based on earlier proposed fragile watermarking algorithm,by adopting adaptive methods along with error-correcting technology,a robust,simple and fast video watermarking algorithm is proposed.In the proposed algorithm,different frames in the video sequence are watermarked with different algorithms in order that the whole bits stream is altered as little as possible.Experimental results show that the proposed new watermarking algorithm is efficient and fairly resistant to second-time coding attack and noise pollution. |
| Keywords: | video watermarking robustness adaptive algorithm motion vectors |
