| Abstract: |
| The process of mathematical expression recognition is introduced.The properties of mathematical expressions and several methods of finding and extracting the mathematical expressions in document are described.Typically,the process of recognition of mathematical expressions consists of two major stages:symbol recognition and structural analysis.The two important issues in expression recognition,i.e.,error detection and correction,and performance evaluation are addressed in depth.In this paper,we emphasize the similarities and differences between systems. |
