A Reversible Watermarking Scheme for High-Fidelity Applications

In this paper, we present a reversible watermaking scheme for high-fidelity applications An improved histogram shifting technique is employed in this method to increase the embedding capacity and amehorate the visual quality of the watermarked image The method ensures that, the modification of each pixel value is at most 1 m single pass embedding In addition two criteria, "near-lossless" and "almost-lossless", are used to evaluate the fidelity of our method Experimental results and performance comparison with other recently proposed reversible watermarking schemes clearly demonstrate that our method outperforms the previous ones
