New steganalysis algorithm using correlation of adjacent pixels
新的利用相邻像素相关性的盲隐写分析算法研究

This paper proposed a new steganalysis technique based on statistical property.The presence of the secret information was judged by the change of adjacent pixels caused by steganography.The new algorithm just considered the adjacent pixel pair in which one was odd and the other was even. The algorithm only needed to count the number of the adjacent pixel pair in which the odd one was greater than the even one and the number of the adjacent pixel pair in which the even one was greater than the odd one, respectively. It could be simply applied and its statistics was small. Experimental comparison shows that the new steganalysis algorithm has a strong detection capability.
