Recognition of Character Strings Printed with Large Alignment Error

Optical character reader (OCR) technology for reading documents, such as monetary transaction documents,is becoming more and more important than ever before.The position of the printed character string issometimeslargely shifted from itsdesignated position,and there may be two or more directionsin spite of one sheet of paper.There are variouscauses, the performance of the printer, a mistake in the printing position designed by the software,a variation in the cell positionscaused by the publishersand by the publishing dates, or even a mistake of the handwriting position. We developed a recognition method for determining which character stringsare to be read in such difficult situations.A method for determining the correspondence of character strings to cellswith a very high successratio wasdeveloped. Thismethod isbased on local and global rules,and effective control of these rules.It wasestimated to have a 99.2 % successratio using an experiment on 11,387character strings. 1
