摘要
数字视频水印算法存在的共同问题就是如何解决水印容量、鲁棒性和不可感知性三者之间的矛盾。基于此,提出一种新的H.264/AVC视频水印算法,算法利用粒子群优化算法选择嵌入载体位置并以此位置构造与水印信息之间的二维映射关系来嵌入水印信息。仿真实验结果表明所提算法能够很好地解决上述三者矛盾问题,具有较强的实用性。
Digital video watermarking algorithms have a common problem that is how to solve the problem of the watermark capacity, robustness and non-perception of the contradiction.Based on this, a flexible algorithm is proposed for H.264/ AVC video watermarking algorithm using particle swarm optimization algorithm to select the carrier location.Then the two-dimensional map relationship between the watermark information and carrier location is constructed.Simulation results show that the proposed algorithm can solve the above three contradictions,which has a strong practicality.
