摘要

视频数字水印技术是当前水印研究中的一个热点.本文提出一种视频数字水印新算法

直接对压缩后的视频数据流进行操作

根据运动矢量的特征值

将水印信息嵌入到运动矢量上

不需要完全解码和再编码过程.所提出的水印算法简单、有效

实现了水印盲检.与嵌入水印前的原视频图像相比

嵌入水印后的视频图像信噪比损失很小.

Abstract

Digital watermarking technology of video image is a hot topic in present watermarking researching area.In this paper

a new watermarking algorithm for video images is proposed.By operating the compressed video data-stream directly

we embed watermarking information into motion vectors according to the motion-vector feature

therefore

complete decoding and re-encoding are unnecessary.The proposed algorithm is simple and efficient.Moreover

watermark can be extracted blindly without original images.Compared with that of image reconstructed from un-watermarked video sequences

PSNRs of watermarked frames are reduced slightly.
