摘要 结构分析是印刷体数学公式识别系统的关键部分,目前相关研究还很欠缺。针对结构分析的基准线方法的一些不足之处,提出一种逆向匹配方法,并结合语义规则对分析后的数学公式进行后处理。实验表明,提出的方法能够有效提高数学公式结构分析的正确率和鲁棒性。 Structure analysis is a crucial course in printed mathematical formula recognition. At present ,the research in this field is rare. In order to resolve the baseline problems of structure analysis, a converse matching method with syntax rules is proposed, and post-processing on the analyzed mathematical formula is carried out. Experimental results show that this method increases the accuracy and robustness of the mathematical formula structure analysis.
