In the domain of steganalysis,almost all of analysis method adopt binary sample to supervise study.(cover image and covert image).The research of this paper revolves around the cover image sample,and bring up the feature discription method of the signal to noise ratio(SNR) and the peak signal-to-noise ratio(PSNR),through this two kinds of feature to describe and quantification the cover image,and verified in theory and pracice,it is suitable to use this two kind of features to discribe the cover image.Cover image and covert image naturally disinguishes when clean picture describe clear.This fresh ration method to net picture,has greatly increased adaptability to the seganalysis method.
