Analysis of complementarity among three sets of the features and their fusion for spatial steganography
Xianfeng Zhao · 2012
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.
