Mathematical Formulas Extraction

As a universal technical language, mathematics has been widely applied in many fields, and it is more accurate than any other languages in describing information. Therefore, numerous mathematical formulas exist in all kinds of documents. There is no doubt that automatic mathematical formulas processing is very important and necessary, of which extract formulas from document images is the first ...

Web application for recognition of mathematical formulas

We present a system for on-line mathematical formulas recognition. The main principles of the method we applied for recognition are explained. It is based on the structural construction paradigm and utilizes a sort of twodimensional grammars called coordinate grammars. Grammar productions are used to model spatial relationships among mathematical symbols. The system itself has been developed as...

EXTRAFOR: Automatic EXTRAction of Mathematical FORmulas

A method for automatic extraction of mathematical formulas from document images without character recognition is described. This method operates into several steps. First, significant symbols of the formula are labeled. Second, this labeling is extended to adjoining symbols by using contextual. Finally, the formula is extracted from the surrounding text by applying some syntactic rules. The pri...

Predictive Input Interface of Mathematical Formulas

Currently, inputting mathematical formulas into a document using a PC requires more effort by users than inputting normal text. This fact inhibits the spreading of mathematical formulas as internet contents. We propose a method for predicting user’s inputs of mathematical formulas using an N-gram model: a popular probabilistic language model in natural language processing. Mathematical formulas...
