NuGet can be used to automatically add files and references to your Visual Studio projects. You can use the Patagames NuGet packages without installing the ZIP package to development with the Tesseract.Net SDK. All the Patagames components are available as NuGet packages at nuget.org.

To install the package, enter the above command into Package Manager Console, and press the Enter key; or search for tesseract.net.sdk through NuGet Package Manager.

Alternative downloads

There are several other ways to get Tesseract.Net SDK - "7-zip" and "ZIP" archive for manual installation. If you don’t specifically require any of these installers, we recommend using the NuGet package.

Language packs

The English language, datafiles are supplied in the standard package. If you need to use other languages, download them separately from this page and put into the tessdata folder.

All language files are downloaded from the official repository Tesseract Open Source OCR Engine

tessdata_best – Best (most accurate) trained models for the Tesseract .Net SDK.

Best results on Google’s eval data, slower, Float models.
These are the only models that can be used as base for finetune training.
Tessdata_best is for people willing to trade a lot of speed for slightly better accuracy.

These models only work with the LSTM OCR engine of Tesseract .Net SDK ver. 2.x

tessdata_fast – Fast integer versions of trained models for the Tesseract .Net SDK.

Best “value for money” in speed vs accuracy, Integer models.
Provides an alternate set of integerized LSTM models which have been built with a smaller network.

• These are a speed/accuracy compromise as to what offered the best "value for money" in speed vs accuracy.
• For some languages, this is still best, but for most not.
• The "best value for money" network configuration was then integerized for further speed.
• When using the models in this repository, only the new LSTM-based OCR engine is supported. The legacy tesseract engine is not supported with these files, so Tesseract's oem modes '0' and '2' won't work with them.

These models only work with the LSTM OCR engine of Tesseract.Net SDK ver. 2.x

tessdata_main - Version of trained models for legacy tesseract engine as well as the new LSTM neural net based engine.

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

The legacy tesseract models have been removed for Indic and Arabic script language files.

These models only work with the Tesseract .Net SDK ver. 2.x

tessdata_v3 - Version of trained models for tesseract 3.04 or 3.05.

These models only work with the Tesseract .Net SDK ver. 1.x
