.TH OCRAD 1 "30 December 2003" "0.6" "GNU Ocrad"
.SH NAME
ocrad \- Optical Character Recognition
.SH SYNOPSIS
.I ocrad
\-afhivV \-b NUMBER \-l MODE \-o FILE \-x FILE [FILES ...]
.Sh DESCRIPTION
.LP
.I 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 outputs text in ISO\-8859\-1
(Latin\-1) charset. Also includes a layout analyser able to separate
the columns or blocks of text normally found on printed pages. It can
be used as a stand\-alone console application, or as a backend to other
programs.
.SH OPTIONS
.TP
.I "\-a", "\-\-append"
Append generated text to the output file instead of overwriting it.
.TP
.I "\-b NUMBER", "\-\-block=NUMBER"
Process only the specified text block, beginning from 1.
Is only useful when used in conjunction with layout analysis (see below).
.TP
.I "\-D LEVEL", "\-\-debug=LEVEL"
The Levels are:
.nf
100 - Show raw block list, unordered
99 - Show recursive block list, unordered
98 - Show main block list, unordered
97 - Show recursive block list, ordered
96 - Show main block list, ordered
95..90 - reserved
89 - Show all blocks from every character
88 - Show main black blocks from every character
87 - Show guess list for every character
86 - Show best guess for every character
.fi
.TP
.I "\-f", "\-\-force"
Force overwrite of output file.
.TP
.I "\-h", "\-\-help"
Print an informative help message describing the options and then exit.
.TP
.I "\-i", "\-\-invert"
Invert image levels (white on black).
.TP
.I "\-l MODE", "\-\-layout=MODE"
Enable page layout analysis. The meaning of
.I MODE
is:
.nf
`0' no analysis at all,
`1' column separation,
`2' full analysis.
.fi
.TP
.I "\-o FILE"
Place the output into
.I FILE
instead of into the standard output.
.TP
.I "\-v", "\-\-verbose"
Verbose mode.
.TP
.I "\-V", "\-\-version"
Print the version number of Ocrad on the standard output and then exit.
.TP
.I "\-x FILE"
Write (export) OCR Results File to
.I FILE
\.
.SH BUGS
If you find a bug in GNU Ocrad, please send electronic mail to
<bug-ocrad@gnu.org>. Include the version number, which you can find by
running `ocrad \-\-version'.
.SH CAVEATS
.IP \(bu 2
Scan directly in b/w mode. Convert from grayscale only if you know what
you are doing.
.IP \(bu 2
For better results the characters should be at least 20 pixels high.
.IP \(bu 2
Merged characters are always a problem. Try to avoid them.
.IP \(bu 2
Very bold or very light (broken) characters are also a problem.
.IP \(bu 2
Always see with your own eyes the pbm file before blaming Ocrad for the
results. Remember the saying, "garbage in, garbage out".
.SH TODO
.IP \(bu 2
Deal with broken characters.
.IP \(bu 2
Make a better layout detector. Every character on its line.
.IP \(bu 2
Separate (more) merged characters.
.IP \(bu 2
Deal better with frames, lines, pictures, etc.
.IP \(bu 2
Change to ISO_8859\-15 (update for ISO_8859\-1 with euro sign).
.IP \(bu 2
Add an option for recognizing ISO_8859\-9 chars (Turkish).
