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.
