Feature-based evaluation for concealment performance of JPEG image information hiding
Qian Si-Jin · Computer Engineering and Applications Journal · 2009
The evaluation of the steganography performance draws wide attention from the public in the research of the informa-tion hiding.This paper proposes a feature-based method to evaluate the JPEG image steganography techniques by contrasting the features abstracted from the images before and after embedding secret messages.In the multi-feature processing,it uses the Prin-cipal Component Analysis(PCA) to get the evaluation value.
