Optical Character Recognition of Old Fonts – A Case Study

Johanna Pirker, Gerhard Wurzinger

Research output: Contribution to journalArticlepeer-review


Extracting text from images of text is a challenging task. Among the greatest
challenges of text recognition is the optical character recognition (OCR) of historic books.
Due to low-quality images, rare fonts, and unknown dictionary standard OCR, software often fails in recognizing these texts. In this paper, we discuss existing OCR systems with a focus on learning strategies, and present an OCR model which is optimized to recognize old books. Additionally, we describe the process to
measure the quality of the outcome.
