GNU Ocrad is an OCR (Optical Character Recognition) program implemented as a filter and based on a feature extraction method. It reads a bitmap image in pbm format 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.

GOCR is an OCR (Optical Character Recognition) program, developed under the GNU Public License. It converts scanned images of text back to text files. Joerg Schulenburg started the program, and now leads a team of developers.
GOCR can be used with different front-ends, which makes it very easy to port to different OSes and architectures. It can open many different image formats, and its quality have been improving in a daily basis.
