Method and apparatus for character recognition

Abstract

This disclosure relates to a character recognition method and apparatus through which highly accurate character recognition is capable of being executed inexpensively and at high speed. Character recognition is raised in speed by executing segmentation of character images from an input image and character recognition from the segmented character images in parallel by separate processors without use being made of a special communication processor. After the character images have been segmented from the input image, the results of segmentation are evaluated and the character images are segmented further based upon the results of evaluation. Methods of evaluation include a method involving finding a standard character size from characters written in character images segmented initially, and adopting the difference between the standard size and the size of each segmented character image, and a method involving quantifying results of character recognition of character images segmented initially, and evaluating the results of quantification.
