PAN source image data reconstruction based on data hiding

Abstract

Although the fusion of Panchromatic(PAN) images and Multi-spectral(MS) images can improve the resolution of remote sensing MS images, the joint adjustments of PAN images and MS images will lead to the original data being completely lost. With the requirement of on-orbit image processing and multiple applications, obtaining fusion images while retaining the source images has become a problem that must be considered. To deal with the problem that the original data is lost after fusion, this proposed method embeds the PAN image object and compression data into the fused image. The experimental results show that the proposed method can reconstruct the object data of the PAN image losslessly and reconstruct the entire PAN image in high quality. The fused image indicators also have no impact.
