Abstract: 针对空间域隐写,分析了小波特征函数统计矩、高阶统计特征和差值像素邻接矩阵3组重要隐写特征间的互补性,利用基于互信息准则和增强特征选择的方法进行特 征融合。分析和实验表明,3组特征间存在互补性,融合后能够得到更好的正确率。
English Abstract: In view of spatial steganography,we discuss the complementarity among three sets of the features including statistical moments of wavelet characteristic functions,high-order statistics,and subtractive pixel adjacency matrix,and we use the mutual information criterion and boosting feature selection to fuse the features.Analytic and experimental results show that the complementarity does exist among the features and the fusion enhances accuracy of steganalysis.
