The ARSIS concept in image fusion: an answer to users needs

The ARSIS concept (from its French name "amelioration de la resolution spatiale par injection de structures" that means improvement of the spatial resolution by structure injection) is briefly presented It offers a framework for the synthesis of multi-modality images at highest spatial resolution by fusion of two sets of images. This concept is comprised of three types of models. These different types are introduced and a set of solutions for implementation proposed. Four solutions are detailed and applied to a satellite Ikonos image of the city of Hasselt, Belgium. The fusion products are analyzed visually and quantitatively. These analyses enhance the benefits of offering a set of solutions to remote sensing end-users in order to fulfill their needs.
