DETECTION OF PERFECT AND APPROXIMATE REFLECTIVE SYMMETRY IN ARBITRARY DIMENSION

Darko Dimitrov, Klaus Kriegel

Abstract

Symmetry detection is an important problem with many applications in pattern recognition, computer vision and computational geometry. In this paper, we propose a novel algorithm for computing a hyperplane of reflexive symmetry of a point set in arbitrary dimension with approximate symmetry. The algorithm is based on the geometric hashing technique. In addition, we consider a relation between the perfect reflective symmetry and the principal components of shapes, a relation that was already a base of few heuristic approaches that tackle the symmetry problem in 2D and 3D. From mechanics, it is known that, if H is a plane of reflective symmetry of the 3D rigid body, then a principal component of the body is orthogonal to H . Here we extend that result to any point set (continuous or discrete) in arbitrary dimension.
