Abstract
The previous steganographic algorithm results in the modification of the image statistic, especially histogram of the coefficients. We propose a method to compensate for the histogram modification due to embedding. The new algorithm estimates the modification before the embedding process has started and modifies the histogram in advance so that the modification due to embedding is less noticeable. We have implemented our methods in Java and performed the extensive experiments with them. The experimental results have shown that our new method improves our previous steganographic algorithms by decreasing distortion and histogram modification.
