Ocrad - The GNU OCR
[ English
| Spanish ]
Introduction
GNU Ocrad is an OCR (Optical Character Recognition) program based on a
feature extraction method. It reads images in pbm (bitmap), pgm
(greyscale) or ppm (color) formats and produces text in byte (8-bit) or
UTF-8 formats.
Also includes a layout analyser able to separate the columns or
blocks of text normally found on printed pages.
Ocrad can be used as a stand-alone console application, or as a
backend to other programs.
Documentation
The manual is available in the info system of the GNU
Operating System. Use info to access the top level info
page. Use info ocrad to access the Ocrad section directly.
