Joint AIHS and Particle Swarm Optimization for Pan-sharpening [PDF]

open access: yesJournal of Geodesy and Geoinformation Science, 2020
Pan-sharpening is a process of obtaining a high spatial and spectral multispectral image (HMS) by combining a low-resolution multispectral image (LMS) with a high-resolution panchromatic image (PAN). In this paper, a pan-sharpening method called PAIHS is

Kriging-Weighted Laplacian Kernels for Grayscale Image Sharpening

open access: yesIEEE Access, 2022
Sharpening filters are used to highlight fine image details, including object edges. However, sharpening filters are very specific to different types of images as they may create undesired edge effects, over-highlight fine details, or emphasize noise ...
