摘要

在H.264/AVC视频压缩域隐写技术中，失真漂移问题极大地影响了信息嵌入的容量和稳定性.本文结合工程实际和实验，发现并指出了漂移传播的实质性规律，提出了相应的改进策略.首先，提出了漂移分级的控制策略，依据不同视频质量及隐蔽性要求自适应地调整失真漂移的传播范围，改进了视频隐写的隐蔽性和安全性；进而通过对漂移影响分层分析，挖掘出了更多的隐写位置，增加了隐写容量及选择隐写方案的灵活性.形成了一种新的扩容视频隐写算法漂移深度控制算法.实验结果和分析表明，该算法能有效地减小嵌入偏移，隐写容量、视频质量及安全性都有较大提升.

Abstract

Distortion drift is a crucial factor for the embedding capacity and stability of H.264/AVC video in compression domain.In this work

considering practical application

we have exploited the substantive regularities that result in distortion drift.Accordingly

some improvements are made to adapt the influence of distortion drift.Firstly

a drift-depth strategy is proposed to improve the embedding invisibility and security

which can control the distortion range according to requirements of video quality.Secondly

through the analysis of the influence of different drift spreading range

more appropriate steganography positions are discovered to increase the embedding capacity and flexibility.Finally

a drift-depth control scheme is presented.Both analytical and simulation results show that our proposed scheme can improve embedding capacity and security

and meanwhile minimize distortion drift.
