Feature Function and Higher-order Statistics Based Blind Image Steganalysis
Tao Jing · Signal Processing · 2008
This paper presents a general blind image steganalysis method based upon Farid's method.In this method,the charac- teristic function was used,and the higher-order statistics of characteristic functions of the picture' s wavelet sub bands and its linear pre- diction error are selected as features to form a classifying model.Experiment results show that this method could detect the pictures with hidden information efficiently.
