Abstract

The embodiment of the invention provides a mathematical formula identification method and device. The method comprises the following steps that: receiving input image data, wherein the contents of the image data comprise written mathematical formula information; determining one or a plurality of operation relationship types matched with the mathematical formula information and one or a plurality of characteristic regions corresponding to each operation relationship type; identifying one or the plurality of characteristic regions to obtain one or a plurality of formula elements; and combining with one or the plurality of operation relationship types to organize one or the plurality of formula elements into a mathematical formula corresponding to the mathematical formula information. Through the embodiment of the invention, the accurate identification of the written mathematical formula is realized, in addition, the structural properties of the mathematical formula are fully utilized in an identification process, character identification difficulty is lowered, the effect and the flow of the whole identification process are optimized, the identification accuracy and the identification speed of the written mathematical formula are improved, and accurate, simple and convenient mathematical formula input experience is provided for users.

Description

technical field [0001] The invention relates to the field of mathematical formula recognition, in particular to a mathematical formula recognition method and a mathematical formula recognition device. Background technique [0002] In the discipline of mathematics, mathematical formulas are an important part of academic literature. At present, MathType and LaTex are mainly used to input mathematical formulas. However, with the further increase in the demand for digitization of documents, the first two methods face a lot of complexity. When editing mathematical formulas, editing is difficult and the efficiency is low. [0003] Online handwritten mathematical formula recognition can provide users with a mathematical formula entry method similar to writing on paper, but the complex structure of mathematical formulas greatly increases the difficulty of computer recognition, and the inaccuracy of handwritten input devices, writing style and speed , the ambiguity of mathematical s...
