Bhattacharyya Distance for Blind Image Steganalysis
Ke Ke, Tao Zhao, Ou Li · 2010
This paper explores Bhattacharyya Distance principle and introduces it to recognize stego algorithms in use. First of all, we select the most important features by the means of applying Bhattacharyya distance. Then, BP neural network is used to classify cover and stego images. Extensive experimental works show that the proposed schemes have satisfactory performance on Jpeg steganography like F5, Outguess, Jsteg and MB2.
