Abstract

A character reading method has enhanced character segmentation accuracy and character string recognition accuracy for reading correctly hand-written addresses on postal matters. The method extracts provisional character patterns from image information of the address character string (step,), creates a table,of tentative character patterns and implements the character classification for the tentative character patterns (step,), extracts, specifically for characters of the street number portion of the address character string, periphery information (vertical and horizontal lengths, vertical/horizontal length ratio, pattern spacings, etc.) of tentative character patterns (step,), and segments the character string into characters accurately based on the information (step,).
