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.
Initial import of ocrad-0.13: GNU Ocrad is an OCR (Optical Character Recognition) program based on a feature extraction method. It reads a bitmap image in pbm or pgm formats and produces text in byte (8-bit) or UTF-8 formats. Ocrad includes a layout analyser able to separate the columns or blocks of text normally found on printed pages.
