Abstract :
In this paper, a new image steganalysis method was proposed based on image gradient energy and entropy features, together with Fraid´s proposed wavelet subband coefficients and higher-order statistics of linear prediction error features. We get 74-dimensional features extraction from images. The support vector machines (SVM) is used to class the images. Experimental results show the method can improve the detection rate compared with Fraid´s algorithm with a lower false negative rate.
