#About
This package contains an OCR engine - libtesseract and a command line program - tesseract.
The lead developer is Ray Smith. The maintainer is Zdenko Podobny. For a list of contributors see AUTHORS and GitHub's log of contributors.
Tesseract has unicode (UTF-8) support, and can recognize more than 100 languages "out of the box". It can be trained to recognize other languages. See Tesseract Training for more information.
Tesseract supports various output formats: plain-text, hocr(html), pdf.
This project does not include a GUI application. If you need one, please see the 3rdParty wiki page.
You should note that in many cases, in order to get better OCR results, you'll need to improve the quality of the image you are giving Tesseract.
The latest stable version is 3.04.01, released in February 2016.
#Brief history
Tesseract was originally developed at Hewlett-Packard Laboratories Bristol and at Hewlett-Packard Co, Greeley Colorado between 1985 and 1994, with some more changes made in 1996 to port to Windows, and some C++izing in 1998.
In 2005 Tesseract was open sourced by HP. Since 2006 it is developed by Google.
#For developers
Developers can use libtesseract C or C++ API to build their own application. If you need bindings to libtesseract for other programming languages, please see the wrapper section on AddOns wiki page.
Documentation of Tesseract generated from source code by doxygen can be found on tesseract-ocr.github.io.
