图像隐写分析中游程检验算法的研究与应用
A Study on Run Length Detecting Algorithm for Steganalysis in Images and Its Application
-
摘要: 随着隐写术在因特网中的广泛应用，隐写分析已经成为学术界研究的热点之一。本文在深入研究BMP图像LSB隐写算法的基础上，在图像隐写分析中提出了游程检验算法并给出了算法原理和工程实现。该算法基于盲检测、不需要训练图像数据库、在满足一定的假设条件下，检测性能优良、算法简单、易于实现，具有一定的实用价值。

Abstract: Steganalysis has become a hot topic recently in academia with steganograph widely used in Internet. Based on research results of Least Significant Bit (LSB) steganography in BMP images,this paper describes a run length detecting algorithm and gives the principle and realization of algorithm.The algorithm based blind detection is practical, effective, easily achieved and need not training image database when certain hypothsis conditions are met. -
