This is a multi-platform OCR (Optical Character Recognition) program.

It can read pnm, pbm, pgm, ppm, some pcx and tga image files.

Currently the program should be able to handle well scans that have their text in one column and do not have tables. Font sizes of 20 to 60 pixels are supported.

If you want to write your own OCR, libgocr is provided in a separate package. Documentation and graphical wrapper are provided in separated packages, too.

Hocr-gtk is a GTK+ based graphical interface to the libhocr library. It can open multiple image formats and uses aspell for internal spell checking.

Lios provides a graphical interface on top of the Cuneiform and Tesseract OCR backends to make OCR processing easier for impaired users, with full autorotation, brightness optimization, rectangle selection, audio feedback, etc.

Tesseract is an open source Optical Character Recognition (OCR) Engine. It can be used directly, or (for programmers) using an API to extract printed text from images. It supports a wide variety of languages. This package includes the command line tool.

Cuneiform is an OCR system. In addition to text recognition it also does layout analysis and text format recognition.

The following languages are supported: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, French, German, Hungarian, Italian, Latvian, Lithuanian, Polish, Portuguese, Romanian, Russian, Serbian, Slovenian, Spanish, Swedish, Turkish and Ukrainian.
