This technical report summarizes the image understanding activities performed by USC during the period October 1, 1982 through September 30, 1983 under contract number F33615-82-K-1786 with the Defense Advanced Research Projects Agency, Information Processing Techniques Office. This contract is monitored by the Air Force Wright Aeronautical Laboratories, Wright-Patterson Air Force Base, Dayton, OH. The purpose of this research program is to develop techniques and systems for understanding images, particularly for mapping applications. This report describes techniques for visual inspection using linear features, relaxation matching for map-matching, techniques for contour matching, a segment-based stereo matching method, use of shadows in the interpretation of aerial images, use of image shading to infer 3-D depth, use of texture for image segmentation, VLSI implementation of graph isomorphism algorithms and a study of suitable architectures for implementing image understanding algorithms.
