Steganalysis attack is to statistically estimate the embedded watermark in the watermarked multimedia, and the estimated watermark may be destroyed by the attacker. The existing methods of false negative probability, however, do not consider the influence of steganalysis attack. This paper proposed the game theory based false negative probability to estimate the impacts of steganalysis attack, as...
In this paper, we proposed an image watermarking algorithm based on Human Visual System's perceptual model in the dual tree complex wavelet domain. We took advantages of the regular and the complex wavelets (perfect reconstruction, approximate shift invariance, and good directional selectivity) for watermark embedding. Firstly we applied the JND (Just Noticeable Difference) to control the watermark...
The traditional BSAO solution on independent component analysis (ICA) needs the ensemble a posteriori information averaging, but in reality, the probability distribution of a posteriori information is unknown, so the premise of equal probability is imprecise, and the geometrical information is discarded. Lagrange constraints neural network (LCNN) solution, which was based on a Lyapunov function------Helmholtz...
