Abstract:Pixel value ordering (PVO) is one of the most commonly used methods in reversible data hiding (RDH). Most PVO methods currently chunk images, categorize them according to the space complexity of the chunks, and adopt different embedding strategies for different chunk categories. Although this approach achieves some results, the utilization of pixel redundancy is still insufficient. In order to expand the embedding capacity of RDH and improve the embedding performance, a high-fidelity reversible data hiding met… Show more
