tessdata

These language data files only work with Tesseract 4.0.0 and newer versions. They are based on the sources in tesseract-ocr/langdata on GitHub. (still to be updated for 4.0.0 - 20180322)

These have models for legacy tesseract engine (--oem 0) as well as the new LSTM neural net based engine (--oem 1).

The LSTM models (--oem 1) in these files have been updated to the integerized versions of tessdata_best on GitHub. So, they should be faster but probably a little less accurate than tessdata_best.

tessdata_fast on GitHub provides an alternate set of integerized LSTM models which have been built with a smaller network. tessdata_fast files are the ones packaged for Debian and Ubuntu.

The legacy tesseract models (--oem 0) have been removed for Indic and Arabic script language files.
