@TECHREPORT{AICPub1540:1979, AUTHOR={Bolles, Robert C.}, TITLE={Symmetry Analysis of Two-Dimensional Patterns for Computer Vision}, ADDRESS={333 Ravenswood Ave, Menlo Park, CA 94025}, INSTITUTION={AI Center, SRI International}, MONTH={June}, NUMBER={186}, YEAR={1979}, KEYWORDS={Computer vision, Two-dimensional, Pattern recognition}, ABSTRACT={A system is described that automatically determines the rotational and mirror symmetries of two-dimensional patters. The properties of patterns that determine their symmetries are delineated, a representation scheme based on these properties is defined, and algorithms to perform the symmetry analysis are presented. An implementation based on the SRI vision module is described.}, NOTE={To be published in the Sixth International Joint Conference on Artificial Intelligence, Tokyo, Japan, 20-23 August 1979.
