combine_tessdata \- combine/extract/overwrite Tesseract data
|
||||
.SH "SYNOPSIS"
|
||||
.sp
|
||||
\fBcombine_tessdata\fR [\fIOPTION\fR] \fIFILE\fR\&...
|
||||
.SH "DESCRIPTION"
|
||||
.sp
|
||||
combine_tessdata(1) is the main program to combine/extract/overwrite tessdata components in [lang]\&.traineddata files\&.
|
||||
.sp
|
||||
To combine all the individual tessdata components (unicharset, DAWGs, classifier templates, ambiguities, language configs) located at, say, /home/$USER/temp/eng\&.* run:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
combine_tessdata /home/$USER/temp/eng\&.
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|
||||
.sp
|
||||
The result will be a combined tessdata file /home/$USER/temp/eng\&.traineddata
|
||||
.sp
|
||||
Specify option \-e if you would like to extract individual components from a combined traineddata file\&. For example, to extract language config file and the unicharset from tessdata/eng\&.traineddata run:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
combine_tessdata \-e tessdata/eng\&.traineddata \e
|
||||
/home/$USER/temp/eng\&.config /home/$USER/temp/eng\&.unicharset
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|
||||
.sp
|
||||
The desired config file and unicharset will be written to /home/$USER/temp/eng\&.config /home/$USER/temp/eng\&.unicharset
|
||||
.sp
|
||||
Specify option \-o to overwrite individual components of the given [lang]\&.traineddata file\&. For example, to overwrite language config and unichar ambiguities files in tessdata/eng\&.traineddata use:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
combine_tessdata \-o tessdata/eng\&.traineddata \e
|
||||
/home/$USER/temp/eng\&.config /home/$USER/temp/eng\&.unicharambigs
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|
||||
.sp
|
||||
As a result, tessdata/eng\&.traineddata will contain the new language config and unichar ambigs, plus all the original DAWGs, classifier templates, etc\&.
|
||||
.sp
|
||||
Note: the file names of the files to extract to and to overwrite from should have the appropriate file suffixes (extensions) indicating their tessdata component type (\&.unicharset for the unicharset, \&.unicharambigs for unichar ambigs, etc)\&. See k*FileSuffix variable in ccutil/tessdatamanager\&.h\&.
|
||||
.sp
|
||||
Specify option \-u to unpack all the components to the specified path:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
combine_tessdata \-u tessdata/eng\&.traineddata /home/$USER/temp/eng\&.
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|
||||
.sp
|
||||
This will create /home/$USER/temp/eng\&.* files with individual tessdata components from tessdata/eng\&.traineddata\&.
|
||||
.SH "OPTIONS"
|
||||
.sp
|
||||
\fB\-e\fR \fI\&.traineddata\fR \fIFILE\fR\&...: Extracts the specified components from the \&.traineddata file
|

<simpara>combine_tessdata(1) is the main program to combine/extract/overwrite

<simpara>Specify option -e if you would like to extract individual components

|

<simpara>Specify option -o to overwrite individual components of the given

[lang].traineddata file. For example, to overwrite language config
|

<simpara>As a result, tessdata/eng.traineddata will contain the new language config
|
||||
and unichar ambigs, plus all the original DAWGs, classifier templates, etc.</simpara>
|
||||
<simpara>Note: the file names of the files to extract to and to overwrite from should

|

.SH "CONFIG FILES AND AUGMENTING WITH USER DATA"
|
||||
.sp
|
||||
Tesseract config files consist of lines with variable\-value pairs (space separated)\&. The variables are documented as flags in the source code like the following one in tesseractclass\&.h:
|
||||
.sp
|
||||
STRING_VAR_H(tessedit_char_blacklist, "", "Blacklist of chars not to recognize");
|
||||
.sp
|
||||
These variables may enable or disable various features of the engine, and may cause it to load (or not load) various data\&. For instance, let\(cqs suppose you want to OCR in English, but suppress the normal dictionary and load an alternative word list and an alternative list of patterns \(em these two files are the most commonly used extra data files\&.
|
||||
.sp
|
||||
If your language pack is in /path/to/eng\&.traineddata and the hocr config is in /path/to/configs/hocr then create three new files:
|
||||
.sp
|
||||
/path/to/eng\&.user\-words:
|
||||
.sp
|

Now, if you pass the word \fIbazaar\fR as a trailing command line parameter to Tesseract, Tesseract will not bother loading the system dictionary nor the dictionary of frequent words and will load and use the eng\&.user\-words and eng\&.user\-patterns files you provided\&. The former is a simple word list, one per line\&. The format of the latter is documented in dict/trie\&.h on read_pattern_list()\&.
|
||||
.SH "HISTORY"
|
||||
.sp
|
||||
The engine was developed at Hewlett Packard Laboratories Bristol and at Hewlett Packard Co, Greeley Colorado between 1985 and 1994, with some more changes made in 1996 to port to Windows, and some C++izing in 1998\&. A lot of the code was written in C, and then some more was written in C++\&. The C++ code makes heavy use of a list system using macros\&. This predates stl, was portable before stl, and is more efficient than stl lists, but has the big negative that if you do get a segmentation violation, it is hard to debug\&.
|
||||
.sp
|
||||
Version 2\&.00 brought Unicode (UTF\-8) support, six languages, and the ability to train Tesseract\&.
|
||||
.sp
|
||||
Tesseract was included in UNLV\(cqs Fourth Annual Test of OCR Accuracy\&. See \m[blue]\fBhttps://github\&.com/tesseract\-ocr/docs/blob/master/AT\-1995\&.pdf\fR\m[]\&. With Tesseract 2\&.00, scripts are now included to allow anyone to reproduce some of these tests\&. See \m[blue]\fBhttps://github\&.com/tesseract\-ocr/tesseract/wiki/TestingTesseract\fR\m[] for more details\&.
|
||||
.sp
|
||||
Tesseract 3\&.00 adds a number of new languages, including Chinese, Japanese, and Korean\&. It also introduces a new, single\-file based system of managing language data\&.
|
||||
.sp
|
||||
Tesseract 3\&.02 adds BiDirectional text support, the ability to recognize multiple languages in a single image, and improved layout analysis\&.

<refsect1 id="_config_files_and_augmenting_with_user_data">
|

<title>CONFIG FILES AND AUGMENTING WITH USER DATA</title>
|
||||
<simpara>Tesseract config files consist of lines with variable-value pairs (space
|
||||
separated). The variables are documented as flags in the source code like
|
||||
the following one in tesseractclass.h:</simpara>
|
||||
<simpara>STRING_VAR_H(tessedit_char_blacklist, "",
|
||||
"Blacklist of chars not to recognize");</simpara>
|
||||
<simpara>These variables may enable or disable various features of the engine, and
|
||||
may cause it to load (or not load) various data. For instance, let’s suppose
|
||||
you want to OCR in English, but suppress the normal dictionary and load an
|
||||
alternative word list and an alternative list of patterns — these two files
|
||||
are the most commonly used extra data files.</simpara>
|
||||
<simpara>If your language pack is in /path/to/eng.traineddata and the hocr config
|
||||
is in /path/to/configs/hocr then create three new files:</simpara>
|
||||
<simpara>/path/to/eng.user-words:</simpara>
|
||||
<blockquote>
|
||||
<literallayout>the
|
||||
quick
|
||||
brown
|
||||
fox
|
||||
jumped</literallayout>
|
||||
</blockquote>
|
||||
<simpara>/path/to/eng.user-patterns:</simpara>
|
||||
<blockquote>
|
||||
<literallayout>1-\d\d\d-GOOG-411
|
||||
www.\n\\\*.com</literallayout>
|
||||
</blockquote>
|
||||
<simpara>/path/to/configs/bazaar:</simpara>
|
||||
<blockquote>
|
||||
<literallayout>load_system_dawg F
|
||||
load_freq_dawg F
|
||||
user_words_suffix user-words
|
||||
user_patterns_suffix user-patterns</literallayout>
|
||||
</blockquote>
|
||||
<simpara>Now, if you pass the word <emphasis>bazaar</emphasis> as a trailing command line parameter
|
||||
to Tesseract, Tesseract will not bother loading the system dictionary nor
|
||||
the dictionary of frequent words and will load and use the eng.user-words
|
||||
and eng.user-patterns files you provided. The former is a simple word list,
|
||||
one per line. The format of the latter is documented in dict/trie.h
|
||||
on read_pattern_list().</simpara>

<title>HISTORY</title>
|
||||
<simpara>The engine was developed at Hewlett Packard Laboratories Bristol and at
|
||||
Hewlett Packard Co, Greeley Colorado between 1985 and 1994, with some more
|
||||
changes made in 1996 to port to Windows, and some C++izing in 1998. A
|
||||
lot of the code was written in C, and then some more was written in C++.
|
||||
The C++ code makes heavy use of a list system using macros. This predates
|
||||
stl, was portable before stl, and is more efficient than stl lists, but has
|
||||
the big negative that if you do get a segmentation violation, it is hard to
|
||||
debug.</simpara>
|
||||
<simpara>Version 2.00 brought Unicode (UTF-8) support, six languages, and the ability
|
||||
to train Tesseract.</simpara>
|
||||
<simpara>Tesseract was included in UNLV’s Fourth Annual Test of OCR Accuracy.
|
||||
See <ulink url="https://github.com/tesseract-ocr/docs/blob/master/AT-1995.pdf">https://github.com/tesseract-ocr/docs/blob/master/AT-1995.pdf</ulink>. With Tesseract 2.00,
|
||||
scripts are now included to allow anyone to reproduce some of these tests.
|
||||
See <ulink url="https://github.com/tesseract-ocr/tesseract/wiki/TestingTesseract">https://github.com/tesseract-ocr/tesseract/wiki/TestingTesseract</ulink> for more
|
||||
details.</simpara>
|
||||
<simpara>Tesseract 3.00 adds a number of new languages, including Chinese, Japanese,
|
||||
and Korean. It also introduces a new, single-file based system of managing
|
||||
language data.</simpara>
|
||||
<simpara>Tesseract 3.02 adds BiDirectional text support, the ability to recognize
|
||||
multiple languages in a single image, and improved layout analysis.</simpara>

||||

|
||||
.SH "DESCRIPTION"
|
||||
.sp
|
||||
The unicharambigs file (a component of traineddata, see combine_tessdata(1) ) is used by Tesseract to represent possible ambiguities between characters, or groups of characters\&.
|
||||
.sp
|
||||
The file contains a number of lines, laid out as follow:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
[num] <TAB> [char(s)] <TAB> [num] <TAB> [char(s)] <TAB> [num]
|
||||

Field five
|
||||
T}:T{
|

.sp
|

contains either 1 or 0\&. 1 denotes a mandatory replacement, 0 denotes an optional replacement\&.
|
||||
T}
|
||||
.TE
|
||||
.sp 1
|
||||
.sp
|
||||
Characters appearing in fields two and four should appear in unicharset\&. The numbers in fields one and three refer to the number of unichars (not bytes)\&.
|
||||
.SH "EXAMPLE"
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
2 \*(Aq \*(Aq 1 " 1
|
||||
1 m 2 r n 0
|
||||
3 i i i 1 m 0
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|
||||
.sp
|
||||
In this example, all instances of the \fI2\fR character sequence \fI\*(Aq\fR\*(Aq will \fBalways\fR be replaced by the \fI1\fR character sequence \fI"\fR; a \fI1\fR character sequence \fIm\fR \fBmay\fR be replaced by the \fI2\fR character sequence \fIrn\fR, and the \fI3\fR character sequence \fBmay\fR be replaced by the \fI1\fR character sequence \fIm\fR\&.
|
||||
.SH "HISTORY"
|
||||
.sp
|
||||
The unicharambigs file first appeared in Tesseract 3\&.00; prior to that, a similar format, called DangAmbigs (\fIdangerous ambiguities\fR) was used: the format was almost identical, except only mandatory replacements could be specified, and field 5 was absent\&.
|
||||
.SH "BUGS"
|
||||
.sp
|
||||
This is a documentation "bug": it\(cqs not currently clear what should be done in the case of ligatures (such as \fIfi\fR) which may also appear as regular letters in the unicharset\&.

||||

.sp
|

Tesseract\(cqs unicharset file contains information on each symbol (unichar) the Tesseract OCR engine is trained to recognize\&.
|
||||
.sp
|
||||
A unicharset file (i\&.e\&. \fIeng\&.unicharset\fR) is distributed as part of a Tesseract language pack (i\&.e\&. \fIeng\&.traineddata\fR)\&. For information on extracting the unicharset file, see combine_tessdata(1)\&.
|
||||
.sp
|
||||
The first line of a unicharset file contains the number of unichars in the file\&. After this line, each subsequent line provides information for a single unichar\&. The first such line contains a placeholder reserved for the space character\&. Each unichar is referred to within Tesseract by its Unichar ID, which is the line number (minus 1) within the unicharset file\&. Therefore, space gets unichar 0\&.
|
||||
.sp
|
||||
Each unichar line in the unicharset file (v2+) may have four space\-separated fields:

<title>DESCRIPTION</title>
|
||||
<simpara>Tesseract’s unicharset file contains information on each symbol
|
||||
(unichar) the Tesseract OCR engine is trained to recognize.</simpara>
|
||||
<simpara>A unicharset file (i.e. <emphasis>eng.unicharset</emphasis>) is distributed as part of a
|
||||
Tesseract language pack (i.e. <emphasis>eng.traineddata</emphasis>). For information on
|
||||
extracting the unicharset file, see combine_tessdata(1).</simpara>
|
||||
<simpara>The first line of a unicharset file contains the number of unichars in
|
||||
the file. After this line, each subsequent line provides information for
|
||||
a single unichar. The first such line contains a placeholder reserved for
|
||||
the space character. Each unichar is referred to within Tesseract by its
|
||||
Unichar ID, which is the line number (minus 1) within the unicharset file.
|
||||
Therefore, space gets unichar 0.</simpara>
|
||||
<simpara>Each unichar line in the unicharset file (v2+) may have four space-separated fields:</simpara>
|
||||
<literallayout class="monospaced">'character' 'properties' 'script' 'id'</literallayout>
|
||||
<simpara>Starting with Tesseract v3.02, more information may be given for each unichar:</simpara>
|
||||
<literallayout class="monospaced">'character' 'properties' 'glyph_metrics' 'script' 'other_case' 'direction' 'mirror' 'normed_form'</literallayout>

.SH "NAME"
|
||||
unicharset_extractor \- extract unicharset from Tesseract boxfiles
|
||||
.SH "SYNOPSIS"
|
||||
.sp
|
||||
\fBunicharset_extractor\fR \fI[\-D dir]\fR \fIFILE\fR\&...
|
||||
.SH "DESCRIPTION"
|
||||
.sp
|
||||
Tesseract needs to know the set of possible characters it can output\&. To generate the unicharset data file, use the unicharset_extractor program on the same training pages bounding box files as used for clustering:
|
||||
.sp
|
||||
.if n \{\
|
||||
.RS 4
|
||||
.\}
|
||||
.nf
|
||||
unicharset_extractor fontfile_1\&.box fontfile_2\&.box \&.\&.\&.
|
||||
.fi
|
||||
.if n \{\
|
||||
.RE
|
||||
.\}
|
||||
.sp
|
||||
The unicharset will be put into the file \fIdir/unicharset\fR, or simply \fI\&./unicharset\fR if no output directory is provided\&.
|
||||
.sp
|
||||
Tesseract also needs to have access to character properties isalpha, isdigit, isupper, islower, ispunctuation\&. all of this auxilury data and more is encoded in this file\&. (See unicharset(5))
|
||||
.sp
|
||||
If your system supports the wctype functions, these values will be set automatically by unicharset_extractor and there is no need to edit the unicharset file\&. On some older systems (eg Windows 95), the unicharset file must be edited by hand to add these property description codes\&.
|
||||
.sp
|
||||
\fBNOTE\fR The unicharset file must be regenerated whenever inttemp, normproto and pffmtable are generated (i\&.e\&. they must all be recreated when the box file is changed) as they have to be in sync\&. This is made easier than in previous versions by running unicharset_extractor before mftraining and cntraining, and giving the unicharset to mftraining\&.
