Abstract :
The off-line handwritten characters recorded on prescribed form documents may be overwritten by the lines of the form documents. Overwritten characters should be isolated in order to be recognized more effectively. However, removal of the lines causes breaks in the overwritten characters. Consequently, a character restoration process is necessary. In this paper, the shape types of overwritten characters are analyzed and a method of restoring characters that have been broken by line removal is proposed. A 97% correct restoration ratio was obtained through this method
