Until now , there is no method which can effectively ext ract characters overlapping position lines ( i. e , preprinted f rames) . This paper considers the case that the characters are handwritten numerals , and proposes a new ext raction method. This method consist s of two steps - coarse processing and fine processing. The first step removes the position lines in order to obtain st ructure feature point s by using mathematical morphology operation.The second step reconst ruct s broken character by considering numeral st ructure features ,and removes redundant st rokes through some st roke smoothing algorithm ,At last ,the above method is applied to the recognition problem of Chinese bank check.
