%0 Report %@ 195 %A Fischler, Martin A. and Barrett, Phyllis %T An Iconic Transform For Sketch Completion and Shape Abstraction %C 333 Ravenswood Ave., Menlo Park, CA 94025 %I AI Center, SRI International %D 1979 %X This paper shows how a simple label propagation technique, in conjunction with some novel ideas about how labels can be applied to an image to express semantic knowledge, lead to the simplification of a number of diverse and difficult image analysis tasks (e.g., sketch completion and shape abstraction). A single algorithm technique, based on skeleton and distance transform concepts, is applied to appropriately labeled images to obtain the desired results. A key point is that the initial semantic labeling is not required at every location in the image, but only at those few critical locations where significant changes or discontinuities occur. %U http://www.ai.sri.com/pubs/files/719.pdf
