Abstract

This paper presents a method to automatically obtain a contour representation of character patterns and rapidly generate high-quality characters of various sizes. Contour representation generates contour vectors and attribute data. The contour vectors are generated without losing information about the characters' shape. The attribute data is used to correct non-uniform widths of vertical and horizontal lines, which is often a problem when characters are transformed to lower resolution. The character generation step reproduces the characters using data obtained in the contour representation step. Since this method represents characters by contours, it does not require as much data. And since non-uniform line widths are corrected rapidly, the characters are of high quality.
