摘要:
针对最新的视频编码标准高效率视频编码(HEVC),提出一种基于帧内模式选择的视频信息隐藏算法.首先,对一幅二值图像进行Arnold置乱和turbo码编码,形成待嵌入的二值信息序列.然后,结合帧内模式选择过程,调制I帧亮度16×16编码单元最优预测模式的奇偶性来实现信息隐藏.由于只在I帧进行信息隐藏,提取时只需部分解码即可提取隐藏信息,无需完全解码与原始视频的参与,实时性较好.实验结果表明:算法对视频质量和比特率的影响较小,且能保证一定的信息隐藏容量,符合视频隐藏算法的基本要求.
Abstract:
This paper proposed an information hidden algorithm which was based on high efficiency video coding(HEVC)intra-prediction modes. Firstly, this algorithm uses Arnold transform and turbo coding method to get a binary information sequence to be embedded. Then, combine with the process of intra frame mode selection, we hide information by modulating the best prediction modes’ parity of I frame luminance block’s coding units. Since the hidden information only be embedded in I frame, during the extraction, only partial decode the steam is needed, we don’t need decode the steam completely and don’t need original video either. Besides, the real-time performance is good. Experimental results show this algorithm only has a little influence on video quality and bit rate and also can ensure a considerable information hiding capacity. Therefore, it is conform to the basic requirements of video hiding algorithm.
