摘要: Segmentation of characters in a character set (10), made by placing dark mark against light background (12), is accomplished establishing vertical pixel projection for each column the image. The projections are filtered with decay parameter so those columns which contain only have highest projection. Thereafter, "cut-points" (points image segmentation) obtained that cut-point coincides whose both local maxima and exceeds predetermined threshold. number such cut-points counted if not significantly greater than number, segmented along cut-points. Otherwise, coincident decreasing threshold to reduce potential
