Abstract:Pansharpening techniques fuse the complementary information from a high-resolution panchromatic (PAN) and low-resolution multispectral (LRMS) images to produce a highresolution multispectral (HRMS) image. However, most of the existing pansharpening methods have been affected in the fullresolution domain due to both the absence of ground truths and unavoidable unknown noises. To address this problem, a new pansharpening method has been proposed that combines enhanced sparse models and gradient-domain guided ima… Show more
