Abstract

Unlike a standard text document, a STEM document not only consists of text information but different components such as tables, figures, captions, mathematical equations etc. This paper presents a novel technique to detect mathematical equations in PDF documents and convert those equations into a more accessible format such as https://static-content.springer.com/image/chp%3A10.1007%2F978-3-031-08648-9_4/518378_1_En_4_IEq1_HTML.gif
Latex
. We use visual features of the document to detect the mathematical equations using object detection and subsequently apply heuristics to the generated bounding boxes to precisely cover the complete equation. These detections are passed to a tool called Maxtract which will rewrite the equations in https://static-content.springer.com/image/chp%3A10.1007%2F978-3-031-08648-9_4/518378_1_En_4_IEq2_HTML.gif
