摘要：

Opposite to most state-of-the-art reversible data hiding (RDH) methods which usually embed data into smooth area for pursuing high PSNR values of the marked image, we propose a new RDH method for improving visual quality of the details information in medical image instead of pursuing high PSNR. The proposed method embeds data into the texture area preferential by the histogram shifting (HS) method and contrast enhancement method to enhance contrast of texture area and improve the image quality in subjective perception. Our experimental results on medical images show that the proposed method can improve image quality when compared with other HS based RDH method.
