Abstract

A Markov random field(MRF)model is defined on a region adjacency graph

and a data fusion strategy for the segmentation of multisource remote sensing images in MRF framework is proposed to fully utilize the complementary information from multisensor remote sensing images for more consistent interpretation. A specific scheme for the segmentation of a set of landsat thematic mapper images and a synthetic aperture radar image is presented in detail. The joint segmentation scheme combines the local feature saliency measure of multisource images with the importance map of human visual system to develop a fusion rule for appropriately incorporating the source reliability to weigh the source influence. Comparative analysis on synthetic and real datasets shows that the new strategy can produce regions with the best homogeneity and the clearest boundary

and can effectively increase the segmentation accuracy.
