Improvement of Reversible Binary Image Data Hiding by Runlength Coding and Histogram Pair

Abstract:

The paper presents a novel method which enhances the capability of the reversible binary image data hiding scheme using runlength(RL)histogram modification algorithm.Before adopting the reversible binary image data hiding scheme using histogram RL modification algorithm,some pretreatments like AND operation and XOR operation are processed first.Experimental results prove its superiority to other methods.

Key words:pretreatment; binary image; reversible data hiding; runlength; histogram pair
