Source training data for Tesseract for lots of languages
Want to re-train tesseract for a specific language, by modifying/augmenting the original training data? Then you have come to the right place!
If you want to find a language data set to run Tesseract, then look at our tessdata repository instead.
To re-create the training of a single language, lang, you need the following:
- All the data in the lang directory.
- The corresponding unicharset/xheights files for the script(s) used by lang.
- All the remaining non-lang-specific files in the top-level directory, such as
font_properties. - You also need to obtain the fonts needed to train the language. Some languages were trained with commercially available fonts, so you will need to buy them in order to reproduce the training exactly, or use substitutes.
