Shifeng Wang · Jisuanji gongcheng · 2010
According to the changes of the historgrams of the first digital distribution and the individual DCT coefficients caused by the steganography algorithm,such as Outguess,F5,Steghide,this paper proposes a new detection algorithm for the JPEG Image.It extracts 144 features by using the first digital distribution and the histograms of individual DCT coefficients,and uses Fisher classifier for recognition.Experimental results show that the algorithm has high detection rate and chronic adaptability.
