This repository contains fast integer versions of trained models for the [Tesseract Open Source OCR Engine](https://github.com/tesseract-ocr/tesseract). This repository contains fast integer versions of trained models for the [Tesseract Open Source OCR Engine](https://github.com/tesseract-ocr/tesseract).
These models only work with the LSTM OCR engine of Tesseract 4.

- Fine tuning/incremental training will **NOT** be possible from these `fast` models, as they are 8-bit integer. - Fine tuning/incremental training will **NOT** be possible from these `fast` models, as they are 8-bit integer.
- 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. - When using the models in this repository, only the new LSTM-based OCR engine is supported.
