## About
This package contains an **OCR engine** - `libtesseract` and a **command line program** - `tesseract`.
Tesseract 4 adds a new neural net (LSTM) based OCR engine which is focused
on line recognition, but also still supports the legacy Tesseract OCR engine of
Tesseract 3 which works by recognizing character patterns. Compatibility with
Tesseract 3 is enabled by using the Legacy OCR Engine mode (--oem 0).
It also needs traineddata files which support the legacy engine, for example
those from the tessdata repository.
The lead developer is Ray Smith. The maintainer is Zdenko Podobny.
