Abstract：
 The present invention is characterized by that on the basis of character block classification selecting partial character blocks, making horizontal projection, dividing text image into subregions, then detecting multiple line subregion, combining character blocks and implementing literal line segmentation of multiple line subregion, then estimating baseline and top line positions of literal line, segmenting the literal line into body-conjunct character field, finally, utilizing feature of character tangent point to find the tangent points positioned on baseline, over baseline and under baseline, and utilizing structural rule to delete overtangential points. The invented character segmentation accuracy can be up to above 99%.
