A method for improving the consistency property of pansharpening algorithms

Abstract : The design of a pansharpening algorithm for enriching a MultiSpectral image with the spatial details of a Panchromatic image should preserve the characteristics of the original dataset. A widely employed quality check consists in verifying the consistency of the fused product, namely the similarity of the original image and a reduced resolution version of the sharpened product. We propose to improve this feature by applying an Iterative Back-Projection algorithm after the fusion procedure. The approach is validated on two datasets, acquired by the Ikonos and WorldView-2 sensors, showing remarkable improvements, especially in conjunction with Component Substitution pansharpening methods.
