Chinese character structure models for handwritten Chinese character recognition

By choosing stroke and sub-stroke as basic components to analyse the composition regularities and deformation regularities of handwritten Chinese character, two models are presented for representing the structure for handwritten Chinese character recognition; the sub-stroke center model and the stroke relation matrix model, as the classifying criteria and methods based on models. According to the proposed models, a two-stage Chinese character recognition system is developed, that applies the sub-stroke center model in the first-stage and stroke relation matrix model in the second-stage. Experimental results show the feasibility and effectiveness of the proposed models.
