Abstract

PURPOSE:To attain sorting by extracting a projected feature from an edge part based upon local matching, absorbing the positional shear of a segment and the variation of line width and extracting a feature effective for identification for rough sorting having small memory capacity. CONSTITUTION:A sorting means 6 refers to the range of a sorting table stored in a sorting range storing means 5 from similarity obtained from edge features x1, x2 in a similarity computing part 3 based on a command from a control circuit 70, identifies a previously determined character category and outputs the category. When the projection processing of similarity is executed and the edge feature is extracted, the positional movement of a segment, the variation of line width and the influence of noise can be absorbed, a decision analysis is applied to the edge feature to extract the feature for emphasizing a difference between categories of a character pattern, and finally rough sorting having small memory capacity and effective for identification can be attained.
