Abstract

In this paper, the problem of stroke recognition has been studied, and the strategies and the algorithms related to the problem are proposed or developed. Based on studying some current methods for Chinese characters strokes recognition, a new method called combining trial is presented. The analysis and results of experiments showed that the method has the advantage of high degree of steadiness.

Highlights

  • Unconstrained handwritten Chinese character recognition has been a difficult research area of character recognition, and its stroke recognition is an important part of structural analysis of Chinese characters

  • For the Chinese character recognition system based on structural analysis, effects of stroke recognition have a major impact on the whole word recognition

  • Because there are a large number of connected strokes that is multiple strokes connected with unconstrained handwritten Chinese characters, and we can not ask the writer to separate a painting to each stroke, stroke recognition includes two processes which are stroke splitting and stroke judgment, requiring to make a split decision from the entire word which comes from an unknown mode and make a decision

Summary

Introduction

Unconstrained handwritten Chinese character recognition has been a difficult research area of character recognition, and its stroke recognition is an important part of structural analysis of Chinese characters. Studies have shown that despite the everchanging of unconstrained handwritten Chinese character, stroke is very stable. For the Chinese character recognition system based on structural analysis, effects of stroke recognition have a major impact on the whole word recognition. Those more typical stroke recognition methods have direct synthesis method, dynamic programming method and so on. Identification module ,combine the extracted strokes serial number string in the same natural stroke, compose them to different types of strokes according to preconditions to complete the stroke recognition. Considering a greater deformation of unconstrained handwritten Chinese character, the algorithm is generally suitable for the occasion to write a more standardized, the high limit handwritten of more restrictive writings and printed texts
