Abstract：
 The geometric cost-semantic identification cost amalgamated off-line hand-written Chinese character segmentation method belongs to the field of character identification technology. Said method includes the following steps: firstly, analyzing row image of inputted off-line hand-written Chinese character, extracting stroke segment, combining stroke segments into subcharacter block, at the same time giving out subcharacter blocks combined geometric cost, utilizing these geometric costs to generate several possible candidate segmentation methods, evaluating every method by using binary syntactic model of language to obtain semantic-identification cost of every segmentation method, finally integrating geometric and semantic identification costs to obtain optimum segmentation identification scheme.
