Abstract:
This paper proposed a reversible watermarking algorithm based on histogram shifting and local complexity in view of the existing problem?of image?distortion for high?capacity?watermarking algorithms. ?In order to obtain?high quality image，this paper classified the cover image block into smooth blocks or complex blocks based on a local complexity function. Then，the smooth block embedded watermark information，?complex?blocks?remained unchanged to increase embedding capacity and enhance image quality. The experimental results show that?compared with other similar algorithms，?this algorithm has?better image?quality and high?embedding capacity.
