Improved DE-Based Reversible Watermarking Using Sorting and Histogram Shifting

In this paper, we present a revised reversible watermarking scheme based on the following techniques: difference expansion, sorting, and histogram shifting. The scheme emphasizes on low distortion with appointed capacity. Experimental results show that this novel algorithm keeps high PSNR. with required payload, and its performance is better than some state-of-the-art algorithms.Computer Science, Information SystemsComputer Science, Theory & MethodsImaging Science & Photographic TechnologyEICPCI-S(ISTP)
