In this forum, we will work with people who are training OCR engines for Polytonic Greek, helping them improve the quality of their engines by correcting specific texts.

Identifying the fonts used in a scanned image

Post by Jonathan Robie »

What's the best way to identify the fonts that are used in a scanned image?

I should make a field guide to this. For OCR purposes, what matters is the performance of a given engine/classifier combination. Ocropus/Ciaconna, e.g., appears to be more comprehensive, allowing various types of Porson fonts to be classified together, which is a really good thing for commentaries. I'm not sure how far this extends: can I classify all Greek fonts together and not have the results degrade (or even improve)? Our Tesseract classifiers are, I believe, currently all completely comprehensive. Gamera/Rigaudon is much pickier, so one would need to make a more specific field-guide. I think it makes sense to start with the categories that I'm currently building up in Ciaconna (the Ocropus-based material).
