Wavelet Steganalysis Based on HMM in Wavelet Domain
Dongqing Xie · Jisuanji gongcheng · 2010
A novel steganalysis method is proposed on the basis of 2-D Hidden Markov Model(HMM) in wavelet domain which is employed to describe the statistics of wavelet coefficients precisely.By modeling wavelet coefficient with 2-D wavelet HMM,classification features are constructed based on parameter sets of HMT forests.Experiments show the technology is applicable for the detection of wavelet domain steganography,especially with higher detecting performance for QIM,MFP,BPCS steganography in wavelet domain.
