In this paper, a universal steganalysis scheme is proposed for images. The scheme is based on the characteristic function (CF) moments of three-level wavelet subbands including the further decomposition coefficients of the first scale diagonal subband. The first three statistical moments of each wavelet band of test image and prediction-error image are selected to form 102 dimensional features for...
In this paper a universal steganalysis scheme is proposed for images. The scheme is based on the characteristic function moments of three-level wavelet subbands including the further decomposition coefficients of the first scale diagonal subband. The first three order statistical moments of each band are selected to form a feature vector for steganalysis. The Euclidean distance is used as the separability...
