Abstract

To tackle the problem that existing pan-sharpening networks cannot preserve spatial information and spectral information simultaneously, this paper proposed a pan-sharpening network guided by wavelet coefficients, which consisted of fusion network and guidance network. The fusion network extracted the multi-level features of PAN and MS images respectively, and performed feature selection and fusion at the same level. The fused features guided the extraction of features at the next level. The guidance network learned the mapping relationship between the wavelet coefficients of the input LRMS/PAN images and HRMS image, and provided extra supervision for the output of the fusion network. Experimental results show that the proposed network can recover as much spatial information as possible while preserving the spectral information of MS images. Comparison experiments on simulated datasets and real datasets also show that the fusion effect of the proposed method is better than other traditional methods and deep learning methods, which has certain value in practice.
