摘　　要：粘连符号切分一直是数学公式识别中的重要问题,也是造成识别错误的主要原因之一,针对这种情况论文用深度学习对粘连符号进行了分割。使用FasterRCNN神经网络进行有监督训练,在训练数据集中包含各种粘连情况,如:水平粘连、垂直粘连以及对角线粘连等,对特殊的粘连情况另外做特殊的处理。通过实验表明这种分割方法使得粘连符号的切分得到显著的提高,同时也提高了数学符号识别的正确率。The segmentation of touching characters is an important problem in the recognition of mathematical formulas,and is also one of the main causes of error recognition.In this case,this paper uses deep learning to divide the touching characters.FasterRCNN neural network is used for supervised training,and contains various adhesion situations in training data set,such as horizontal adhesion,vertical adhesion and diagonal adhesion.Special treatment for special adhesions is also done.The experiment shows that the segmentation method makes the segmentation of the touching characters significantly improved,At the same time,the correct rate of mathematical symbol recognition is also improved.
