In recent years, deep learning-based methods have been extensively utilized in remote sensing image scene classification and achieved remarkable performance. The wide geographical coverage resolution differences of images result significant within-class diversity between-class similarity, hindering the further improvement accuracy.

Hyperspectral image (HSI) fusion refers to the reconstruction of a high-resolution HSI by fusing low-resolution (LR-HSI) and multispectral (HR-MSI) over same scene.
