A region-based image fusion method was proposed.The source images firstly were split into different regions with various spatial characteristics and then performed the different fusion methods for each particular region independently.Experiments were implemented with two categories of remote sensing image fusion—multispectral image vs.panchromatic image and multispectral image vs.radar image.The results show that using the proposed method which could be not only obtained better quality fusion result,but also easily controlled the contribution of these components in the fused product and chosen the appropriate fusion method,which satisfied the user′s needs.
