摘要: 在研究已有的二值图像信息隐藏和隐写分析算法基础上,给出图像“模式”的概念,按修改图像模式中心像素对人体视觉的影响程度将图像模式分成3类,建立二值图像最佳嵌入位置模式库,通过分析二值文本图像的模式在嵌入信息前后的变化特征,提出基于模式分析的二值文本图像隐写分析算法。实验证明,该算法的性能较佳。

Abstract: This paper proposes the idea of image “pattern” by investigating all kinds of information hiding and steganalysis algorithms. It divides the patterns into three categories according to human visual effect degree for flipping the center pixel of the pattern, establishes the best embedding pattern storehouse for binary images, statistically analyzes the pattern’s changing characteristics before and after embedding information for binary text images, and proposes a steganalysis algorithm based on pattern analysis for the binary text images. Experiments prove that the algorithm performs well.

Key words: pattern analysis, text image, steganalysis
