摘要
通过对高比特率信息隐藏算法的改进,设计了一种视频嵌入视频的方案,实现了隐秘视频信息的安全传输.实验结果表明,改进的信息隐藏算法比原有算法隐藏信息操作速度快20%;含有隐藏信息的宿主视频没有出现明显的视觉质量下降,亮度分量的峰值信噪比平均下降仅0.22 dB,提取隐藏信息平均比特误码率仅为0.015%.
An high bitrate information hiding algorithm is improved, and a scheme of video in video is implemented for secret video information transmission. Experimental results show that improved information hiding algorithm saves 20% time than the original algorithm, and the host video in which is embedded numerous auxiliary information has little visual quality decline, PSNR Y of host video only degrades 0.22 dB in average, and the average bit error rate of hidden information is 0. 015%.
