ABSTRACT:
A character recognition system comprises means for receiving a first binary image of a plurality of characters; segmenting means for separating the first binary image into a plurality of second binary images corresponding to the plurality of characters in the first binary image; normalizing means for reducing variations among the characters, which normalizing means comprises stroke adjusting means for processing the second binary images to adjust strokes of the characters to a predetermined thickness, size normalization means for processing the second binary images to proportionally adjust the overall size of the characters to a predetermined overall size, and slant correction means for processing the second binary images to reduce a slant with respect to a predetermined axis of the characters; and recognizer means coupled to the normalizing means for processing the normalized second binary images to determine which character is represented by each of the normalized second binary images.
