Abstract

This paper describes the implementation of a non-linear 2D shape abstraction technique. The abstraction procedure systematically simplifies the shape's description using a group of predefined `rewrite rules.' This procedure operates on a new compact and efficient two dimensional shape representation. The abstraction technique generates a detailed scale space representation of the shape being abstracted. This paper provides a method for analyzing this representation to determine the significant shape descriptions. These significant descriptions are used to produce a reduced scale space description of the shape, for use by an object recognition module. The work described in this paper forms a module in a system being developed at Kingston University, to inspect surface mounted technology circuit boards for defects.
