Abstract: This paper proposes a steganalysis scheme using the difference histogram and image calibration. The message embedding makes the correlation with the neighboring pixels weaken and the random ...

As for the space discretization, the most popular choices are finite difference [15, 39, 41] and finiteelement [3, 4, 16, 24, 37, 39, 41] methods (in that order of preference). We propose a new ...
