A PVO-based Reversible Data Hiding Scheme Using Variable Difference

摘要：

　　In order to improve the PSNR of the marked image,an improved high-fidelity reversible data hiding algorithm was proposed based on Pixel-Value-Ordering.There are many different forms of prediction errors used to embed information,each of which leads to different pixel shift rate.One certain appropriate form of prediction errors was selected for embedding data,which can not only provide adequate embedding capacity,but also increase the PSNR of marked image.The algorithm can extract the secret information and restore the original image without any damage.Experimental results show that the proposed algorithm compared with the original PVO algorithm can effectively improve the visual quality of the marked image.
