Ocrad is an OCR (Optical Character Recognition) program implemented
as a filter and based in a feature extraction method. It reads a bitmap
image in pbm format and outputs text in ISO-8859-1 (Latin-1) charset.
It can be used as a stand-alone console application, or as a backend to
other programs.

See the file INSTALL for compilation and installation instructions.

Try "ocrad --help" for usage instructions.

Caveats.
This program can't deal (yet) with "slanted" fonts.
For better results the characters should be at least 20 pixels high.
Merged characters are always a problem. Try to avoid them.
And remember the saying, "garbage in, garbage out".

Ideas, comments, patches, donations (hardware, money, etc), etc are welcome.
