一种基于图像内容检索技术的数字视频水印算法

利用基于Tamura纹理特征的图像内容检索技术，通过对原始视频图像进行Tamura纹理特征分析，提取具有极大纹理特征值的某些帧来嵌入水印，水印嵌入算法辅助采用小波变换。仿真试验表明，本算法能抵抗高斯、剪切、泊声等常见的水印攻击。同时算法对视频压缩也表现出良好的健壮性, 对保护视频版权有一定的指导意义。

A Digital Video Watermarking Algorithm Based on Content Image Retrieval

Utilizing Image Retrieval Based on Tamura and Texture Features by analyzing Tamura texture feature of original video source, we extract some frame with max maximum texture features to embed watermarking. Watermark Embedding Algorithm is assisted by wavelet transform.A simulation case shows that the method can efficiently resist watermarking attacks such as Gauss, possion, cropping. And this method shows a good robust to video compression and has a significance of guidance to protect the copyright of video.
