    On-Line Handwriting Cursive Recognition

    • 摘要: 英文手写识别既是模式识别问题又是一个搜索问题,其计算复杂度非常高.针对这个问题,提出了一些新的方法来解决联机英文手写识别问题.首先,运用一些先验知识对所获得的基线进行调整;其次,针对英文识别过程的复杂度太高,提出了快速有效的解码算法——主笔划分层构筑Viterbi算法;最后,将多阶段的分类信息融合到决策过程中,较大幅度地提高了系统的性能.在Unipen训练集和实验室数据集上测试取得了良好的效果.

       

      Abstract: On-line cursive handwriting recognition is both a pattern recognition and search problem. Its computing complexity is very high. Some new methods are proposed to overcome these problems. First, some prior knowledge, such as middle of primitive and delayed stroke, is used to adjust the reference line. Then, based on the special primitive attribute of handwriting cursive, a fast valid decoding algorithm, that is, the primitive level building beam viterbi (PLBBV), is presented. Finally, a combining classifiers algorithm that uses all the classifiers' measurement to make decision is represented. The tests on the Unipen training set and the laboratory set reveal the feasibility of the proposed method.
