'' 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.
