基于JPEG图像的模块化可逆信息隐藏方法
Reversible data hiding method for JPEG images based on modularized optimization
摘要
Abstract
The existing RDH methods usually determine the modification model and the embedding parameters adaptively ac-cording to the given image,in order to optimize the performance.However,the existing optimization manners will lead to the high computational complexity and the unacceptable time cost.This paper proposed a modularized RDH method for JPEG ima-ges,to improve the efficiency of the adaptive optimization.The candidate embedding solutions were defined as the existing pa-rameter sets which were verified effective under different cases.Therefore,it generated a so-called universal modification mo-del set that was suitable for different images.Each modification model was defined as the optimal embedding points for the multiple histograms modification mechanism.During the embedding,the appropriate modification model was adaptively selected from the pre-set solution set,based on the given image.Compared with five related works on the USC-SIPI database,the peak signal-to-noise ratio(PSNR)of the proposed method can be improved 0.03～1.81 dB.In the terms of the file size increase,the results of the proposed method can reduce 12.4％and 5.1％respectively,compared with the two typical methods.The experimental results demonstrate that,the proposed method outperforms the mainstream classic methods,in the terms of the quality of the marked image and the file size preservation.Compared with the state-of-the-arts,the proposed method can achieve the similar adaptive performance,while keeping a low computational complexity.关键词
