摘要
针对新的HEVC高效视频编码标准特性,提出了一种基于版权保护的视频水印算法。分析了HEVC同上一版视频格式标准H.264/AVC之间的编码差别,在研究HEVC格式的基础上为其设计了一个独特的水印算法。该算法首先对水印图片进行置乱处理,然后将水印嵌入到亮度分量离散正弦变换(DST)分块的中频系数中。实验结果证明,该算法对HEVC视频有很好的嵌入和提取效果,并可以抵抗多种形式的视频攻击。
As far as the features of new efficient video coding standard concerned, a video watermarking algorithm is proposed based on the copyright protection. This paper analyzes the coding differences between HEVC version and its former of H.264/AVC video format standard. On the basis of the research of HEVC furmat, a unique watermarking algorithm is designed. Firstly, the watermarking image is scramblingly processed, and then the watermark is embedded into the intermediate frequency coefficient that is transformed from the luminance of through the discrete sine transform（DST）. The experiment results show that the algorithm has good effect of embedding and extraction to HEVC video and can resist many ,forms of video attacks.
