中文摘要：
自然书写的脱机中文文本行识别是当今字符识别领域的一个难题.为降低文本行识别中负样本的干扰,文中提出了一个概率模型,将负样本作为一种信息来源,与单字符的识别信息、文本行的几何信息等进行融合.简单地使用两个分类器,就可以实现上述概率模型.在多人手写真实文本数据库中进行的实验表明,当无语言模型和使用二元语言模型时,文中所提方法的正确识别率分别达到61.29%和72.73%,体现了该方法的有效性.
英文摘要：
The recognition of unconstrained handwritten offline Chinese text line is a difficult problem in current character recognition domain.In order to reduce the interferences from negative samples during text line recognition,a probabilistic model is developed.In this model,negative samples are treated as an information source and are integrated with other kinds of information such as the recognition information of isolated characters and the geometric information of text line.By using only two classifiers,the proposed probabilistic model can be successfully implemented.Experimental results on a real multiple-writer handwritten text database show that,by using the proposed method,the correct recognition rates reach 61.29% without any language model and 72.73% with a bi-gram language model,respectively,which means that the method is effective.
