Ocrad is an optical character recognition program, and part of the GNU Project. It is free software, and is licensed under the GNU GPL.
Based on a feature extraction method, it reads images in portable pixmap formats known as Portable anymap, and produces text in byte (8-bit) or UTF-8 formats. Also included is a layout analyser, able to separate the columns or blocks of text normally found on printed pages.
User interface
Ocrad can be used as a stand-alone command-line application, or as a back-end to other programs.
Kooka, which was the KDE environment's default scanning application until KDE 4, can use Ocrad as its OCR engine.[2] Because development of the program ceased in 2007, current versions of KDE no longer contain Kooka. Ocrad can be also used as an OCR engine in OCRFeeder.[3]
History
Ocrad has been developed by Antonio Diaz Diaz since 2003. Version 0.7 was released in February 2004, 0.14 in February 2006 and 0.18 in May 2009. It is written in C++.
Archives of the bug-ocrad mailing list go back to October 2003.[4]
