Fusion-based Resolution Enhancement of Satellite Images: Comparative Study and Performance Evaluation

摘要

Fusion becomes an important technique for improving resolution of satellite images. This importance is established from the ability of such technique to combine relevant information from several images, of a scene, into a single image. The constructed image is more informative than any one of the original images. This paper first presents a literature survey of the most recent fusion techniques concerned with satellite images. Then, it gives a performance evaluation of such techniques for enhancing resolution of color images considering full scene images of different regions with resolutions taken by Spot-4 and Landsat-8 satellites. Finally, it presents a comparison among the fusion techniques using different evaluation criteria.
