Research in Expert Interactive Cartographic Systems.
Abstract
Applications of interactive expert system techniques to the domain of automated cartography were studied in the context of the SRI Image Understanding Testbed, extended to include Symbolics Lisp Machines and the SRI ImagCalc(TM) software support system. As a sample domain, we chose to work mainly on the problem of locating generic cultural objects in aerial imagery. The discovery of such objects was accomplished by defining a generic model for rectilinear objects, along with rules for parsing the image geometry and correcting probable errors of the segmentation algorithm. These tools permit the semantic resegmentation of an initial syntactic scene partition to yield well-delineated buildings. The method owes its success to the combined utilization of both high-level and low-level knowledge about the target object context and the image. Keywords: Spatial reasoning; Cultural object detection; Image segmentation.
