摘要：This paper addresses a development of spatial relationextraction from remotely sensed image based onquad tree representation. The input image is firsttransformed into a hierarchical structure of quadtrees,which is composed of quadtree, segmentationquadtree; homogeneous region quadtree and spatialrelation quadtree. With the description of hierarchicalquadtrees ,appropriate spatial relation can be extracted,which is from local to global as more and more objectknowledge is used. The strategy that is calleddiscrimination graphs algorithm for spatial relationextraction in terms of quadtree representation ispresented . The result obtained in this paper is clearand can easily be used for remotely sensed imageinterpretation
