%X According to the adjacent pixels of natural image have a certain correlation, propose steganalysis method which based on correlation measurement of image pixels. Firstly, Using Hilbert space filling curve scanning pixels of the image and pixels of each planes, constructing one-dimensional sequence. Then correlate the correlation coefficient and the ratio of the difference between the adjacent pixels to measure the correlation. Extract the features input to the classifier, the experiments show that the way to detect, achieve good results.
