-

DESCRIPTION

-
-

combine_lang_model(1) generates a starter traineddata file that can be used to train an LSTM-based neural network model. It takes as input a unicharset and an optional set of wordlists. It eliminates the need to run set_unicharset_properties(1), wordlist2dawg(1), some non-existent binary to generate the recoder (unicode compressor), and finally combine_tessdata(1).

combine_tessdata - combine/extract/overwrite/list/compact Tesseract data

-
-
-
-

SYNOPSIS

-
-

combine_tessdata [OPTION] FILE…

-
-
-
-

DESCRIPTION

-
-

combine_tessdata(1) is the main program to combine/extract/overwrite/list/compact -tessdata components in [lang].traineddata files.

-

To combine all the individual tessdata components (unicharset, DAWGs, -classifier templates, ambiguities, language configs) located at, say, -/home/$USER/temp/eng.* run:

-
-
-
combine_tessdata /home/$USER/temp/eng.
-
-

The result will be a combined tessdata file /home/$USER/temp/eng.traineddata

-

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:

-
-
-
combine_tessdata -e tessdata/eng.traineddata \
-  /home/$USER/temp/eng.config /home/$USER/temp/eng.unicharset
-
-

The desired config file and unicharset will be written to -/home/$USER/temp/eng.config /home/$USER/temp/eng.unicharset

-

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:

-
-
-
combine_tessdata -o tessdata/eng.traineddata \
-  /home/$USER/temp/eng.config /home/$USER/temp/eng.unicharambigs
-
-

As a result, tessdata/eng.traineddata will contain the new language config -and unichar ambigs, plus all the original DAWGs, classifier templates, etc.

-

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.

-

Specify option -u to unpack all the components to the specified path:

-
-
-
combine_tessdata -u tessdata/eng.traineddata /home/$USER/temp/eng.
-
-

This will create /home/$USER/temp/eng.* files with individual tessdata -components from tessdata/eng.traineddata.

-
-
-
-

OPTIONS

-
-

-c .traineddata FILE…: - Compacts the LSTM component in the .traineddata file to int.

-

-d .traineddata FILE…: - Lists directory of components from the .traineddata file.

-

-e .traineddata FILE…: - Extracts the specified components from the .traineddata file

-

-l .traineddata FILE…: - List the network information.

-

-o .traineddata FILE…: - Overwrites the specified components of the .traineddata file - with those provided on the command line.

Compatibility with Tesseract 3 is enabled by using the Legacy OCR Engine mode (--oem 0). -It also needs [traineddata](https://tesseract-ocr.github.io/tessdoc/Data-Files.html) files which support the legacy engine, for example those from the [tessdata](https://github.com/tesseract-ocr/tessdata) repository. - -Stefan Weil is the current lead developer. Ray Smith was the lead developer until 2018. The maintainer is Zdenko Podobny. For a list of contributors see [AUTHORS](https://github.com/tesseract-ocr/tesseract/blob/main/AUTHORS) -and GitHub's log of [contributors](https://github.com/tesseract-ocr/tesseract/graphs/contributors). - -Tesseract has **unicode (UTF-8) support**, and can **recognize [more than 100 languages](https://tesseract-ocr.github.io/tessdoc/Data-Files-in-different-versions.html)** "out of the box". - -Tesseract supports **[various image formats](https://tesseract-ocr.github.io/tessdoc/InputFormats)** including PNG, JPEG and TIFF. - -Tesseract supports **various output formats**: plain text, hOCR (HTML), PDF, invisible-text-only PDF, TSV, ALTO and PAGE. - -You should note that in many cases, in order to get better OCR results, you'll need to **[improve the quality](https://tesseract-ocr.github.io/tessdoc/ImproveQuality.html) of the image** you are giving Tesseract. - -This project **does not include a GUI application**. If you need one, please see the [3rdParty](https://tesseract-ocr.github.io/tessdoc/User-Projects-%E2%80%93-3rdParty.html) documentation. - -Tesseract **can be trained to recognize other languages**. -See [Tesseract Training](https://tesseract-ocr.github.io/tessdoc/Training-Tesseract.html) for more information. - -## Brief history - -Tesseract was originally developed at Hewlett-Packard Laboratories Bristol UK and at Hewlett-Packard Co, Greeley Colorado USA between 1985 and 1994, with some more changes made in 1996 to port to Windows, and some C++izing in 1998. In 2005 Tesseract was open sourced by HP. From 2006 until November 2018 it was developed by Google. - -Major version 5 is the current stable version and started with release -[5.0.0](https://github.com/tesseract-ocr/tesseract/releases/tag/5.0.0) on November 30, 2021.

SYNOPSIS

-
-

tesseract FILE OUTPUTBASE [OPTIONS]… [CONFIGFILE]…

-
-
-
-

DESCRIPTION

-
-

tesseract(1) is a commercial quality OCR engine originally developed at HP -between 1985 and 1995. In 1995, this engine was among the top 3 evaluated by -UNLV. It was open-sourced by HP and UNLV in 2005, and has been developed -at Google until 2018.

-
-
-
-

IN/OUT ARGUMENTS

-
-
-
-FILE -
-
-

- The name of the input file. - This can either be an image file or a text file.
- Most image file formats (anything readable by Leptonica) are supported.
- A text file lists the names of all input images (one image name per line). - The results will be combined in a single file for each output file format - (txt, pdf, hocr, xml).
- If FILE is stdin or - then the standard input is used. -

-
-
-OUTPUTBASE -
-
-

- The basename of the output file (to which the appropriate extension - will be appended). By default the output will be a text file - with .txt added to the basename unless there are one or more - parameters set which explicitly specify the desired output.
- If OUTPUTBASE is stdout or - then the standard output is used. -

-
-
-
-
-
-

OPTIONS

-
-
-
--c CONFIGVAR=VALUE -
-
-

- Set value for parameter CONFIGVAR to VALUE. Multiple -c arguments are allowed. -

-
-
---dpi N -
-
-

- Specify the resolution N in DPI for the input image(s). - A typical value for N is 300. Without this option, - the resolution is read from the metadata included in the image. - If an image does not include that information, Tesseract tries to guess it. -

-
-
--l LANG -
-
--l SCRIPT -
-
-

- The language or script to use. - If none is specified, eng (English) is assumed. - Multiple languages may be specified, separated by plus characters. - Tesseract uses 3-character ISO 639-2 language codes - (see LANGUAGES AND SCRIPTS). -

-
-
---psm N -
-
-

- Set Tesseract to only run a subset of layout analysis and assume - a certain form of image. The options for N are: -

-
-
-
0 = Orientation and script detection (OSD) only.
-1 = Automatic page segmentation with OSD.
-2 = Automatic page segmentation, but no OSD, or OCR. (not implemented)
-3 = Fully automatic page segmentation, but no OSD. (Default)
-4 = Assume a single column of text of variable sizes.
-5 = Assume a single uniform block of vertically aligned text.
-6 = Assume a single uniform block of text.
-7 = Treat the image as a single text line.
-8 = Treat the image as a single word.
-9 = Treat the image as a single word in a circle.
-10 = Treat the image as a single character.
-11 = Sparse text. Find as much text as possible in no particular order.
-12 = Sparse text with OSD.
-13 = Raw line. Treat the image as a single text line,
-     bypassing hacks that are Tesseract-specific.
-
-
-
---oem N -
-
-

- Specify OCR Engine mode. The options for N are: -

-
-
-
0 = Original Tesseract only.
-1 = Neural nets LSTM only.
-2 = Tesseract + LSTM.
-3 = Default, based on what is available.
-
-
-
---tessdata-dir PATH -
-
-

- Specify the location of tessdata path. -

-
-
---user-patterns FILE -
-
-

- Specify the location of user patterns file. -

-
-
---user-words FILE -
-
-

- Specify the location of user words file. -

-
-
-CONFIGFILE -
-
-

- The name of a config to use. The name can be a file in tessdata/configs - or tessdata/tessconfigs, or an absolute or relative file path. - A config is a plain text file which contains a list of parameters and - their values, one per line, with a space separating parameter from value.
- Interesting config files include: -

-
    -
  • -

    -alto — Output in ALTO format (OUTPUTBASE.xml). -

    -
    • -
  • -

    -hocr — Output in hOCR format (OUTPUTBASE.hocr). -

    -
    • -
  • -

    -page — Output in PAGE format (OUTPUTBASE.page.xml). - The output can be customized with the flags: - page_xml_polygon — Create polygons instead of bounding boxes (default: true) - page_xml_level — Create the PAGE file on 0=linelevel or 1=wordlevel (default: 0) -

    -
    • -
  • -

    -pdf — Output PDF (OUTPUTBASE.pdf). -

    -
    • -
  • -

    -tsv — Output TSV (OUTPUTBASE.tsv). -

    -
    • -
  • -

    -txt — Output plain text (OUTPUTBASE.txt). -

    -
    • -
  • -

    -get.images — Write processed input images to file (OUTPUTBASE.processedPAGENUMBER.tif). -

    -
    • -
  • -

    -logfile — Redirect debug messages to file (tesseract.log). -

    -
    • -
  • -

    -lstm.train — Output files used by LSTM training (OUTPUTBASE.lstmf). -

    -
    • -
  • -

    -makebox — Write box file (OUTPUTBASE.box). -

    -
    • -
  • -

    -quiet — Redirect debug messages to /dev/null. -

    -
    • -
-
-
-

It is possible to select several config files, for example -tesseract image.png demo alto hocr pdf txt will create four output files -demo.alto, demo.hocr, demo.pdf and demo.txt with the OCR results.

-

Nota bene: The options -l LANG, -l SCRIPT and --psm N -must occur before any CONFIGFILE.

-

LANGUAGES AND SCRIPTS

-
-

To recognize some text with Tesseract, it is normally necessary to specify -the language(s) or script(s) of the text (unless it is English text which is -supported by default) using -l LANG or -l SCRIPT.

-

Selecting a language automatically also selects the language specific -character set and dictionary (word list).

-

Selecting a script typically selects all characters of that script -which can be from different languages. The dictionary which is included -also contains a mix from different languages. -In most cases, a script also supports English. -So it is possible to recognize a language that has not been specifically -trained for by using traineddata for the script it is written in.

-

More than one language or script may be specified by using +. -Example: tesseract myimage.png myimage -l eng+deu+fra.

-

https://github.com/tesseract-ocr/tessdata_fast provides fast language and -script models which are also part of Linux distributions.

-

For Tesseract 4, tessdata_fast includes traineddata files for the -following languages:

-

afr (Afrikaans), -amh (Amharic), -ara (Arabic), -asm (Assamese), -aze (Azerbaijani), -aze_cyrl (Azerbaijani - Cyrilic), -bel (Belarusian), -ben (Bengali), -bod (Tibetan), -bos (Bosnian), -bre (Breton), -bul (Bulgarian), -cat (Catalan; Valencian), -ceb (Cebuano), -ces (Czech), -chi_sim (Chinese simplified), -chi_tra (Chinese traditional), -chr (Cherokee), -cos (Corsican), -cym (Welsh), -dan (Danish), -deu (German), -deu_latf (German Fraktur Latin), -div (Dhivehi), -dzo (Dzongkha), -ell (Greek, Modern, 1453-), -eng (English), -enm (English, Middle, 1100-1500), -epo (Esperanto), -equ (Math / equation detection module), -est (Estonian), -eus (Basque), -fas (Persian), -fao (Faroese), -fil (Filipino), -fin (Finnish), -fra (French), -frm (French, Middle, ca.1400-1600), -fry (West Frisian), -gla (Scottish Gaelic), -gle (Irish), -glg (Galician), -grc (Greek, Ancient, to 1453), -guj (Gujarati), -hat (Haitian; Haitian Creole), -heb (Hebrew), -hin (Hindi), -hrv (Croatian), -hun (Hungarian), -hye (Armenian), -iku (Inuktitut), -ind (Indonesian), -isl (Icelandic), -ita (Italian), -ita_old (Italian - Old), -jav (Javanese), -jpn (Japanese), -kan (Kannada), -kat (Georgian), -kat_old (Georgian - Old), -kaz (Kazakh), -khm (Central Khmer), -kir (Kirghiz; Kyrgyz), -kmr (Kurdish Kurmanji), -kor (Korean), -kor_vert (Korean vertical), -lao (Lao), -lat (Latin), -lav (Latvian), -lit (Lithuanian), -ltz (Luxembourgish), -mal (Malayalam), -mar (Marathi), -mkd (Macedonian), -mlt (Maltese), -mon (Mongolian), -mri (Maori), -msa (Malay), -mya (Burmese), -nep (Nepali), -nld (Dutch; Flemish), -nor (Norwegian), -oci (Occitan post 1500), -ori (Oriya), -osd (Orientation and script detection module), -pan (Panjabi; Punjabi), -pol (Polish), -por (Portuguese), -pus (Pushto; Pashto), -que (Quechua), -ron (Romanian; Moldavian; Moldovan), -rus (Russian), -san (Sanskrit), -sin (Sinhala; Sinhalese), -slk (Slovak), -slv (Slovenian), -snd (Sindhi), -spa (Spanish; Castilian), -spa_old (Spanish; Castilian - Old), -sqi (Albanian), -srp (Serbian), -srp_latn (Serbian - Latin), -sun (Sundanese), -swa (Swahili), -swe (Swedish), -syr (Syriac), -tam (Tamil), -tat (Tatar), -tel (Telugu), -tgk (Tajik), -tha (Thai), -tir (Tigrinya), -ton (Tonga), -tur (Turkish), -uig (Uighur; Uyghur), -ukr (Ukrainian), -urd (Urdu), -uzb (Uzbek), -uzb_cyrl (Uzbek - Cyrilic), -vie (Vietnamese), -yid (Yiddish), -yor (Yoruba)

-

To use a non-standard language pack named foo.traineddata, set the -TESSDATA_PREFIX environment variable so the file can be found at -TESSDATA_PREFIX/tessdata/foo.traineddata and give Tesseract the -argument -l foo.

-

For Tesseract 4, tessdata_fast includes traineddata files for the -following scripts:

-

Arabic, -Armenian, -Bengali, -Canadian_Aboriginal, -Cherokee, -Cyrillic, -Devanagari, -Ethiopic, -Fraktur, -Georgian, -Greek, -Gujarati, -Gurmukhi, -HanS (Han simplified), -HanS_vert (Han simplified, vertical), -HanT (Han traditional), -HanT_vert (Han traditional, vertical), -Hangul, -Hangul_vert (Hangul vertical), -Hebrew, -Japanese, -Japanese_vert (Japanese vertical), -Kannada, -Khmer, -Lao, -Latin, -Malayalam, -Myanmar, -Oriya (Odia), -Sinhala, -Syriac, -Tamil, -Telugu, -Thaana, -Thai, -Tibetan, -Vietnamese.

-

The same languages and scripts are available from -https://github.com/tesseract-ocr/tessdata_best. -tessdata_best provides slow language and script models. -These models are needed for training. They also can give better OCR results, -but the recognition takes much more time.

-

Both tessdata_fast and tessdata_best only support the LSTM OCR engine.

-

There is a third repository, https://github.com/tesseract-ocr/tessdata, -with models which support both the Tesseract 3 legacy OCR engine and the -Tesseract 4 LSTM OCR engine.

CONFIG FILES AND AUGMENTING WITH USER DATA

-
-

Tesseract config files consist of lines with parameter-value pairs (space -separated). The parameters are documented as flags in the source code like -the following one in tesseractclass.h:

-

STRING_VAR_H(tessedit_char_blacklist, "", - "Blacklist of chars not to recognize");

-

These parameters 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.

-

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:

-

/path/to/eng.user-words:

-
-
the
-quick
-brown
-fox
-jumped
-
-
-

/path/to/eng.user-patterns:

-
-
1-\d\d\d-GOOG-411
-www.\n\\\*.com
-
-
-

/path/to/configs/bazaar:

-
-
load_system_dawg     F
-load_freq_dawg       F
-user_words_suffix    user-words
-user_patterns_suffix user-patterns
-
-
-

Now, if you pass the word bazaar as a CONFIGFILE 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().

-
-
-
-

ENVIRONMENT VARIABLES

-
-
-
-TESSDATA_PREFIX -
-
-

- If the TESSDATA_PREFIX is set to a path, then that path is used to - find the tessdata directory with language and script recognition - models and config files. - Using --tessdata-dir PATH is the recommended alternative. -

-
-
-OMP_THREAD_LIMIT -
-
-

- If the tesseract executable was built with multithreading support, - it will normally use four CPU cores for the OCR process. While this - can be faster for a single image, it gives bad performance if the host - computer provides less than four CPU cores or if OCR is made for many images. - Only a single CPU core is used with OMP_THREAD_LIMIT=1. -

HISTORY

-
-

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.

-

Version 2.00 brought Unicode (UTF-8) support, six languages, and the ability -to train Tesseract.

-

Tesseract was included in UNLV’s Fourth Annual Test of OCR Accuracy. -See https://github.com/tesseract-ocr/docs/blob/main/AT-1995.pdf. -Since Tesseract 2.00, -scripts are now included to allow anyone to reproduce some of these tests. -See https://tesseract-ocr.github.io/tessdoc/TestingTesseract.html for more -details.

-

Tesseract 3.00 added a number of new languages, including Chinese, Japanese, -and Korean. It also introduced a new, single-file based system of managing -language data.

-

Tesseract 3.02 added BiDirectional text support, the ability to recognize -multiple languages in a single image, and improved layout analysis.

-

Tesseract 4 adds a new neural net (LSTM) based OCR engine which is focused -on line recognition, but also still supports the legacy Tesseract OCR engine of -Tesseract 3 which works by recognizing character patterns. Compatibility with -Tesseract 3 is enabled by --oem 0. This also needs traineddata files which -support the legacy engine, for example those from the tessdata repository -(https://github.com/tesseract-ocr/tessdata).

-

For further details, see the release notes in the Tesseract documentation -(https://tesseract-ocr.github.io/tessdoc/ReleaseNotes.html).

NAME

-
-

unicharambigs - Tesseract unicharset ambiguities

-
-
-
-

DESCRIPTION

-
-

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.

-

The file contains a number of lines, laid out as follow:

-
-
-
[num] <TAB> [char(s)] <TAB> [num] <TAB> [char(s)] <TAB> [num]
-
-
- - - - - - - - - - - - - - - - - - - - -
-Field one -
-		 -

-the number of characters contained in field two -

-
-Field two -
-		 -

-the character sequence to be replaced -

-
-Field three -
-		 -

-the number of characters contained in field four -

-
-Field four -
-		 -

-the character sequence used to replace field two -

-
-Field five -
-		 -

-contains either 1 or 0. 1 denotes a mandatory -replacement, 0 denotes an optional replacement. -

-
-

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).

-
-
-
-

EXAMPLE

-
-
-
-
v1
-2       ' '     1       "     1
-1       m       2       r n   0
-3       i i i   1       m     0
-
-

The first line is a version identifier. -In this example, all instances of the 2 character sequence '' will -always be replaced by the 1 character sequence "; a 1 character -sequence m may be replaced by the 2 character sequence rn, and -the 3 character sequence may be replaced by the 1 character -sequence m.

-

Version 3.03 and on supports a new, simpler format for the unicharambigs -file:

-
-
-
v2
-'' " 1
-m rn 0
-iii m 0
-
-

In this format, the "error" and "correction" are simple UTF-8 strings -separated by a space, and, after another space, the same type specifier -as v1 (0 for optional and 1 for mandatory substitution). Note the downside -of this simpler format is that Tesseract has to encode the UTF-8 strings -into the components of the unicharset. In complex scripts, this encoding -may be ambiguous. In this case, the encoding is chosen such as to use the -least UTF-8 characters for each component, ie the shortest unicharset -components will make up the encoding.

-
-
-
-

HISTORY

-
-

The unicharambigs file first appeared in Tesseract 3.00; prior to that, a -similar format, called DangAmbigs (dangerous ambiguities) was used: the -format was almost identical, except only mandatory replacements could be -specified, and field 5 was absent.

-
-
-
-

BUGS

-
-

This is a documentation "bug": it’s not currently clear what should be done -in the case of ligatures (such as fi) which may also appear as regular -letters in the unicharset.

-
-

DESCRIPTION

-
-

Tesseract’s unicharset file contains information on each symbol -(unichar) the Tesseract OCR engine is trained to recognize.

-

A unicharset file (i.e. eng.unicharset) is distributed as part of a -Tesseract language pack (i.e. eng.traineddata). For information on -extracting the unicharset file, see combine_tessdata(1).

-

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.

-

Each unichar line in the unicharset file (v2+) may have four space-separated fields:

-
-
-
'character' 'properties' 'script' 'id'
-
-

Starting with Tesseract v3.02, more information may be given for each unichar:

-
-
-
'character' 'properties' 'glyph_metrics' 'script' 'other_case' 'direction' 'mirror' 'normed_form'
-
-

Entries:

-
-
-character -
-
-

-The UTF-8 encoded string to be produced for this unichar. -

-
-
-properties -
-
-

-An integer mask of character properties, one per bit. - From least to most significant bit, these are: isalpha, islower, isupper, - isdigit, ispunctuation. -

-
-
-glyph_metrics -
-
-

-Ten comma-separated integers representing various standards - for where this glyph is to be found within a baseline-normalized coordinate - system where 128 is normalized to x-height. -

-
    -
  • -

    -min_bottom, max_bottom: the ranges where the bottom of the character can - be found. -

    -
    • -
  • -

    -min_top, max_top: the ranges where the top of the character may be found. -

    -
    • -
  • -

    -min_width, max_width: horizontal width of the character. -

    -
    • -
  • -

    -min_bearing, max_bearing: how far from the usual start position does the - leftmost part of the character begin. -

    -
    • -
  • -

    -min_advance, max_advance: how far from the printer’s cell left do we - advance to begin the next character. -

    -
    • -
-
-
-script -
-
-

-Name of the script (Latin, Common, Greek, Cyrillic, Han, null). -

-
-
-other_case -
-
-

-The Unichar ID of the other case version of this character - (upper or lower). -

-
-
-direction -
-
-

-The Unicode BiDi direction of this character, as defined by - ICU’s enum UCharDirection. (0 = Left to Right, 1 = Right to Left, - 2 = European Number…) -

-
-
-mirror -
-
-

-The Unichar ID of the BiDirectional mirror of this character. - For example the mirror of open paren is close paren, but Latin Capital C - has no mirror, so it remains a Latin Capital C. -

-
-
-normed_form -
-
-

-The UTF-8 representation of a "normalized form" of this unichar - for the purpose of blaming a module for errors given ground truth text. - For instance, a left or right single quote may normalize to an ASCII quote. -

-
-
-
-
-
-

EXAMPLE (v2)

-
-
-
-
; 10 Common 46
-b 3 Latin 59
-W 5 Latin 40
-7 8 Common 66
-= 0 Common 93
-
-

";" is a punctuation character. Its properties are thus represented by the -binary number 10000 (10 in hexadecimal).

-

"b" is an alphabetic character and a lower case character. Its properties are -thus represented by the binary number 00011 (3 in hexadecimal).

-

"W" is an alphabetic character and an upper case character. Its properties are -thus represented by the binary number 00101 (5 in hexadecimal).

-

"7" is just a digit. Its properties are thus represented by the binary number -01000 (8 in hexadecimal).

-

"=" is not punctuation nor a digit nor an alphabetic character. Its properties -are thus represented by the binary number 00000 (0 in hexadecimal).

-

Japanese or Chinese alphabetic character properties are represented by the -binary number 00001 (1 in hexadecimal): they are alphabetic, but neither -upper nor lower case.

CAVEATS

-
-

Although the unicharset reader maintains the ability to read unicharsets -of older formats and will assign default values to missing fields, -the accuracy will be degraded.

-

Further, most other data files are indexed by the unicharset file, -so changing it without re-generating the others is likely to have dire -consequences.

-
-
-
-

HISTORY

-
-

The unicharset format first appeared with Tesseract 2.00, which was the -first version to support languages other than English. The unicharset file -contained only the first two fields, and the "ispunctuation" property was -absent (punctuation was regarded as "0", as "=" is in the above example.

NAME

-
-

unicharset_extractor - Reads box or plain text files to extract the unicharset.

-
-
-
-

SYNOPSIS

-
-

unicharset_extractor [--output_unicharset filename] [--norm_mode mode] box_or_text_file […]

-

Where mode means: - 1=combine graphemes (use for Latin and other simple scripts) - 2=split graphemes (use for Indic/Khmer/Myanmar) - 3=pure unicode (use for Arabic/Hebrew/Thai/Tibetan)

-
-
-
-

DESCRIPTION

-
-

Tesseract needs to know the set of possible characters it can output. -To generate the unicharset data file, use the unicharset_extractor -program on training pages bounding box files or a plain text file:

-
-
-
unicharset_extractor fontfile_1.box fontfile_2.box ...
-
-

The unicharset will be put into the file ./unicharset if no output filename is provided.

-

NOTE Use the appropriate norm_mode based on the language.

OPTIONS

-
-

-t - Verify that a given dawg file is equivalent to a given wordlist.

-

-r 1 - Reverse a word if it contains an RTL character.

-

-r 2 - Reverse all words.

-

-l <short> <long> - Produce a file with several dawgs in it, one each for words - of length <short>, <short+1>,… <long>

-
-
-
-

ARGUMENTS

-
-

WORDLIST - A plain text file in UTF-8, one word per line.

-

DAWG - The output DAWG to write.

-

lang.unicharset - The unicharset of the language. This is the unicharset - generated by mftraining(1).
