Abstract
In converting line image data of a minute shape portion into polygonal line data, a pattern recognition apparatus is designed so as to determine polygonal line data from line image data by conventional polygonal line conversion processing technique, to presume an optimum shaping for for a shape formed by a group of the polygonal line data from the relationship with the drawing therearound, and to judge whether a path of the shaping form passes on the line image at a given constant percentage or larger. This permits an approximation of a minute shape portion likely to undergo an influence from digital noise to polygonal line with a high reliability.
