SORTING PROCESSOR OF CHARACTER PATTERN

摘要

PURPOSE:To enable recognition of a character pattern using deformed characters, by observing the character pattern from plural coordinate axis directions and counting the directional contribution degree of a character line in the direction orthogonal to the coordinte axis as well as the resemblance between two directional contribution degrees at each position on the coordinate axis. CONSTITUTION:A binary coded handwritten character pattern is stored 1, and the position and size of the pattern are normalized by a normalizing processor 2 with the centroid and a secondary moment. A device 3 frames characters in a forward region of W mesh of a character framing frame around on the centroid in order to cope with the extreme extrusion of a character line at the place near a contour of a handwritten character. Thus the outside of a frame is removed. A smoothing processor 4 fills up or removes the recessing/projecting parts of one black point mesh at the contour part of the character line. A feature extractor 5 performs a scan from the coordinate axis of direction K and then from direction M when it crosses a character to extract features. A sorter 6 obtains matching with a dictionary table.
