A Vectrization Method for Drawings Using a Combination of Core Line Extraction and Thinning

Abstract

A coreline extraction method based on contour vectors has been proposed. The basic idea of the method is to generate the medial axis from contour vectors sited opposite each other. This method has merits on the time efficiency, the ability to get line width, and the ablity to separate filled area. The method, however, cannot work well on destorted parts. We propose an improved method to overcome the deficiency using the combination method with the coreline extractions and thinning.
