README
1Description 2 3GNU Ocrad is an OCR (Optical Character Recognition) program and library 4based on a feature extraction method. It reads images in pbm (bitmap), 5pgm (greyscale) or ppm (color) formats and produces text in byte (8-bit) 6or UTF-8 formats. The pbm, pgm and ppm formats are collectively known as 7pnm. 8 9Ocrad includes a layout analyser able to separate the columns or blocks 10of text normally found on printed pages. 11 12For best results the characters should be at least 20 pixels high. If 13they are smaller, try the --scale option. Scanning the image at 300 dpi 14usually produces a character size good enough for ocrad. 15 16See the file INSTALL for compilation and installation instructions. 17 18Try "ocrad --help" for usage instructions. 19 20Caveats. 21Merged characters are always a problem. Try to avoid them. 22Very bold or very light (broken) characters are also a problem. 23Always see with your own eyes the pnm file before blaming ocrad for the 24results. Remember the saying, "garbage in, garbage out". 25 26Ideas, comments, patches, donations (hardware, money, etc), etc, are welcome. 27 28--------------------------- 29 30Debug levels ( option -D ) 31100 - Show raw block list. 32 99 - Show recursive block list. 33 98 - Show main block list. 34 96..97 - reserved. 35 95 - Show all blocks from every character before recognition. 36 94 - Show main black blocks from every character before recognition. 37 90..93 - reserved. 38 89 - Show all blocks from every character. 39 88 - Show main black blocks from every character. 40 87 - Show guess list for every character. 41 86 - Show best guess for every character. 42 80..85 - reserved. 43 78..79 - reserved. 44 7X - X = 0 Show page as bitmap. 45 X = 1 Show page as bitmap with marked zones. 46 X = 2 Show page as bitmap with marked lines. 47 X = 4 Show page as bitmap with marked characters. 48 49 50Copyright (C) 2003-2019 Antonio Diaz Diaz. 51 52This file is free documentation: you have unlimited permission to copy, 53distribute and modify it. 54 55The file Makefile.in is a data file used by configure to produce the 56Makefile.
