ABSTRACT

Many image fusion techniques have been developed to produce high spatial-resolution color imagery from panchromatic (PAN) and multispectral (MULTI) satellite imagery. The conventional techniques could be subdivided into three categories such as spectral substitution, arithmetic merging and spatial domain. This research applied fusion techniques, corresponding to each fusion category, to PAN and MULTI scenes of WorldView-2 satellite. Individual fused images were evaluated in terms of spectral and spatial distortion. The study found that fused imagery, based on spatial domain, were superior to those fusion results from spectral substitution and arithmetic merging. It is anticipated that spatial-domain fusion technique would be appropriate in producing fused imagery that could play a role of input data for online image map as well as thematic map at a large scale.
