STRUCTURAL ANALYSIS OF PRINTED MATHEMATICAL EXPRESSIONS BASED ON COMBINED STRATEGY
Recognizing mathematical expressions from document images is a key problem in the conversion of scientific document into electronic form. It is also a difficult part in the development of recognition technology. In this paper, we present an efficient method of parsing printed mathematics notation, which is based on the combined strategy of baseline and minimum spanning tree method. The syntactic and semantic knowledge is summarized so that a logical arrangement of the mathematical expressions can be obtained automatically. Experiments have been carried out for many types of expressions in printed documents and our method has shown favorable results.
