基于运动矢量的鲁棒视频水印方案

提出一种基于运动矢量的鲁棒视频水印方案.采用生命游戏理论、差错控制技术对水印进行预处理,综合考虑视频运动矢量幅值和图像纹理特征来选择运动矢量自适应地嵌入水印,并对嵌入水印后的运动矢量进行误差补偿和码字矫正.仿真实验证明,该方案财视频的码率改变、帧重组、帧删除等攻击有较好的鲁棒性,且具有较好的不可见性、实时性和安全性.

Robust Video Watermarking Scheme Based on Motion Vectors

The writer proposes a robust video watermarking scheme based on motion vectors.It uses life game theory and error control technology to do the watermark pretreatment.It embeds the watermark self-adaptively to the motion vectors according to their amplitude value and the image texture character value.Finally,it does error compensation and code rectification to the motion vectors embedded the watermarking.Experiment results show that the proposed scheme is robust to code rate changing,frame regrouping,frame d...
