A Novel General Steganalysis Technique Based on Cover Image Describing

On Internet,There are a large number of steganographic programs to hide message in digital image.This paper proposes a novel general steganalysis technique based on cover image describing.It can detect effectively whether or not secret messages are in digital image by this technique.Cover image is quantitatively described fully by texture feature and imaginary eigenvalue decomposition(IED)feature.It can increase detection speed by a reducing dimension processor,and the curse of dimensionality problem can be solved.One classifier based on a flexile super-ellipse-sphere is designed,and detection performance is improved.
