Abstract
To recognize a handwritten check mark on a pre-printed character with OCR (Optical Character Recognition), we need to separate the pre-print and the superimposed check mark. By the previous method, an unmarked form image and marked one are matched and overlapping part is removed. Then the remaining pattern is regarded as a superimposed mark pattern. Therefore when the mark pattern and the pre-print is overlapped, the overlapping part is removed with the pre-print. It sometimes causes a decision error of the existence of the check mark. In this paper, we propose a new method to separate a superimposed pattern to preprints using directional decomposition of an image for precise recognition of the check mark.
