摘要:视频隐写是以视频为载体的隐写技术,根据嵌入时载体视频是否经过压缩编码将视频隐写分为基于原始视频的隐写和基于压缩视频的隐写两个大类。该文介绍了几种常见的基于压缩视频的隐写算法,给出了一般原理模型,对AC系数、DC系数和运动矢量等编码单元上隐写算法进行了简单介绍,提出了提高隐藏率的基本思想。
Video steganography is a video steganography technology, according to the embedded video compression coding is the carrier through the video steganography is divided into the original video steganography and steganalysis based on compressed video based on two categories. This paper introduces several common write algorithm of compressed video based on the implicit, general principle of model, algorithm written hidden AC coefficients, DC coefficients and motion vectors encoding unit were introduced, raises the basic thought hidden rate.
