# Symmetry Analysis of Two-Dimensional Patterns for Computer Vision

Robert C. Bolles

*Proceedings of the Sixth International Joint Conference on Artificial Intelligence*.

## Abstract

A system is described that automatically determines the rotational and mirror symm et ries of two-dimensional patterns. The properties of patterns that determine their symmetries are delineated, a representation scheme based on thes e properties is defined, and algorithms to perform the symmetry analysis are presented. An implementation based on the SRI vision mcdule is described.
