The recommended audience for this document are developers who want to
|
||
|
|
use Microsoft Visual Studio 2008 with `Tesseract-OCR
|
||
|
|
<http://code.google.com/p/tesseract-ocr/>`_. If you simply want to *run*
|
||
|
|
`tesseract` or its various language training applications, then see the
|
||
|
|
`ReadMe <http://code.google.com/p/tesseract-ocr/wiki/ReadMe>`_. You'll
|
||
|
|
find instructions there on how to download tesseract's Windows
|
||
|
|
installer.
|
||
|
|
|
||
|
|
|Tesseractocr| consists of:
|
||
|
|
|
||
|
|
+ `libtesseract` -- the static (or dynamic) library that does all the
|
||
|
|
actual work. As of February 2012 it consists of 260+ `C++` files
|
||
|
|
along with 290+ header files.
|
||
|
|
|
||
|
|
+ `tesseract.exe` -- the command-line OCR engine. It's built from a
|
||
|
|
single, small `C++` file that just calls functions in
|
||
|
|
`libtesseract`. There currently isn't very much documentation on how
|
||
|
|
to use `tesseract.exe`, but you can look at what's there in the
|
||
|
|
repository's `doc
|
||
|
|
<http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc>`_
|
||
|
|
subdirectory.
|
||
|
|
|
||
|
|
+ Language packs -- needed by `tesseract.exe` in order to recognize
|
||
|
|
particular languages.
|
||
|
|
|
||
|
|
.. _training-applications:
|
||
|
|
|
||
|
|
+ Language training applications -- used to teach `tesseract.exe` new
|
||
|
|
languages. Each has their own (very brief) man page in the `doc
|
||
|
|
<http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc>`_
|
||
|
|
subdirectory and include:
|
||
|
|
|
||
|
|
+ `ambiguous_words.exe` -- generate sets of words Tesseract is likely
|
||
|
|
to find ambiguous
|
||
|
|
|
||
|
|
+ `classifier_tester` -- tests a Tesseract character classifier on
|
||
|
|
data as formatted for training
|
||
|
|
|
||
|
|
+ `cntraining.exe` -- character normalization training
|
||
|
|
|
||
|
|
+ `combine_tessdata.exe` -- combine/extract/overwrite Tesseract data
|
||
|
|
|
||
|
|
+ `dawg2wordlist.exe` -- convert a Tesseract DAWG to a wordlist
|
||
|
|
|
||
|
|
+ `mftraining.exe` -- feature training
|
||
|
|
|
||
|
|
+ `shapeclustering.exe` -- shape clustering training
|
||
|
|
|
||
|
|
+ `unicharset_extractor.exe` -- extract unicharset from Tesseract
|
||
|
|
boxfiles
|
||
|
|
|
||
|
|
+ `wordlist2dawg.exe` -- convert a wordlist to a DAWG
|
||
|
|
|
||
|
|
