A High Capacity Reversible Watermarking Scheme Based on an Integer Transform

In this paper, we present a novel reversible watermarking scheme based on an improved integer transform. Our scheme puts emphasis on the high embedding capacity with low distortion. For instance, one can embed more than 1.5 BPP in Lena by the proposed scheme in a single pass embedding, and meanwhile the resulting PSNR is relatively good. Experiment results show that the performance of our scheme is better than some state-of-the-art algorithms.
