e-rara: Recognizing mathematical Formulas and Tables

The ETH Library enables access to a large number of scientific titles on e-rara.ch, which are provided with OCR. However, these old prints often also contain mathematical formulas and tables. Such content is largely lost during OCR processing, and often only individual numbers or letters are recognized. Special characters, systems of equations and tabular arrangements are typically missing in the full text.

Title
The aim of this project is to develop a procedure for selected content, how this information could be restored.
