Abstract
In this paper we address six problems we have encountered when sharpening multi-spectral imagery (MSI) using panchromatic (PAN) images and describe methods we have developed to solve them. We also describe a PANsharpening method that can be used for hyper-spectral data where the PAN-band does not cover all spectral bands. In this paper we compare a number of currently used PAN-sharpening methods. The comparison is done (1) visually creating true and false color composites and (2) compute their radiometric fidelity with the Wang-Bovik quality index.
