摘要

在H.264/AVC的帧内预测环节

调制H.264/AVC编码中I帧4×4亮度块的帧内预测模式实现信息隐藏.这种调制基于该模式与待隐藏比特之间的映射规则进行.宿主4×4块的具体位置由各块自身特点结合密钥所指定的嵌入位置模板确定.信息的提取过程不需要原始视频内容

也不需完全解码

而只要对码流中的帧内预测模式进行解码即可.

Abstract

During the intra prediction step of H.264/AVC video compression standard

information hiding is implemented by modifying the intra prediction modes of qualified intra 4×4 luma blocks.The modulation is based on the mapping rules between these modes and the hidden bits.The specific positions of the host 4×4 blocks are determined by the features of every block and a position template indicated by the key.The detection of hidden information needs no original media

and merely requires decoding the intra prediction modes from bit stream rather than decoding the whole video.
