隐秘图像嵌入与检测算法比较研究

compare stdudy on embedding and detetecting algorithm of steganograph

本文从参数估计理论中的Fisher信息和Cramer-Rao不等式出发,将隐秘图像嵌入与检测的一般过程抽象出来,以系统的观念来研究各种嵌入与检测算法,并给出了一种给定原始图像和隐秘消息的嵌入算法和给定隐秘图像的检测算法优劣统计特性判定准则。

this paper starts with Fisher information and Cramer- Rao inequation,abstracts the process of embedding and detecting, studies variants of algorithms in view of systems,and gives a formula to decide which methods is best in the end.
