Mathematical expression recognition is an important problem about pattern recognition, because mathematical expression is an essential part of scientific literature. This paper focused on two aspects, first of all, About the recognition of on-line handwritten mathematical expressions, this paper elaborates the structural analysis strategy from the perspective of the general mathematical expression, we bring forward a feasible solution to the overall structural analysis by using some pretreatment methods, such as dominating relationships, hard-regulations, function merging, and so on. The results show that this method can overcome some shortcomings of traditional structure analysis methods, and also it can dispose some recognition errors that often appear in the space structure and logical structure of the on-line handwriting recognition system effectively, such as symbol overlapping and handshaking, complex layer structure, the table structure and so on. Secondly, on this basis, We have contrived an online handwriting recognizing system of mathematical expression based on an embedded equipment, which supports in the use of the languages of the minority, such as Uyghur and Kazakh languages .For the features of mathematical expression recognizing, and from the point of ensuring the system’s efficiency , this paper has constructed an embedded platform, on which the capability of the system has been tested, and it has compared the data gained from the test with those in PC , which offers a gist to improve the algorithm and perfect the system
As to recognizing mathematical expressions, we have designed online handwriting recognizing systems of mathematical expressions, MatheWriter and Embedded-Mathe Writer, which have succeeded to be embedded in Office (like Word) and mobile equipments (like PDA). The paper expounds the system structure and basic functions of recognition system. On the basis of these studies, it also expounds the recognizing technology of mathematical expressions based on the Net and Internet Explorer, and from the perspective of Web's characteristics, the Web-Based Mathe Writer is developed to help the mathematical workers find a more convenient and free model to solve difficult problems of expression input. Furthermore, it sets up a platform for inquiring into how to build a more natural and harmonious humancomputer environment under the environment of Ubiquitous computing through the design and realization ofexpression editor ofthis non-keyboard input
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
