Matching 2D Shapes Using Their Symmetry Sets

Abstract

We introduce strings, based on the Symmetry Set, to describe shapes. These strings denote links between pairs of extrema of the curvature together with a length measure. An algorithm is given to match strings of different types of shapes. Examples show the usability of the presented theory.
