Abstract

The basic principle of reversible data hiding with contrast enhancement ab-breviated as RDH-CE is to enhance the perceived contrast of stego images using an reversible data-embedding manner. Considering that existing RDH-CE methods can only enhance the global contrast of the image but ignore or may even reduce the local contrast, an RDH-CE method combining K-means clustering with multiple features is proposed in this paper. K-means clustering with multiple features is employed to yield multiple histograms. Adaptive contrast enhancement based on the local properties of multiple histograms is applied to enhance the local contrast as well as global contrast while achieving satisfactory embedding capacity. The experimental results also demonstrate the effectiveness of the proposed method.
