Re: Disable Special characters?

[zdenko podobny]

Hello,

if I correctly understood "Comment by ffournel, Mar 30, 2010" on
http://code.google.com/p/tesseract-ocr/wiki/FAQ we can achieved the same
behavior by creating config file (e.g. digits in directory
tessdata/configs/) with line:

tessedit_char_whitelist 0123456789

and than to run:

C:>tesseract.exe nine.tif out tessdata/configs/nobatch
tessdata/configs/digits

Re: Extracting files from .tessdata

[zdenko podobny]

Hello Ramon,

for extending existing language you need "Tif/Box pairs" see
http://code.google.com/p/tesseract-ocr/wiki/FAQ and there "How do I add just
one character or one font to my favourite language, without having to
retrain from scratch?"

Unfortunately tif/box pairs are provided only for eng, deu, fra, ita, nld
and spa languages... So you can wait that somebody will someday release
tif/box pairs for your language or you will start training from scratch. I
choose second option and this is reason why I started with testing of
training process for  tesseract 3.00.

BR,

Zdenko

Re: Spaces situation in Training image

[zdenko podobny]

Hello,

http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract:

It is *ABSOLUTLEY VITAL* to space out the text a bit when printing, so up
the inter-character and inter-line spacing in your word processor. Not
spacing text out sufficiently will cause "FAILURE! box overlaps no blobs or
blobs in multiple rows" errors during tr file generation, which leads to
FATALITY - 0 labelled samples of "x", which leads to "Error: X classes in
inttemp while unicharset contains Y unichars" and you can't use your nice
new data files. This situation will improve in the future, as we are working
on a solution, but for 3.00 APPLY_BOXES errors remain the most problematic
difficulty for people training tesseract.


so you do not need to create space between words, but it is important you
have enough space between character.

Best regards,

Zdenko

Announcement: new version of pyTesseractTrainer available

[zdenko podobny]

Hello,

I would like to announce new version 1.01 of pyTesseractTrainer - successor
of 
tesseractTrainer.py
Version
1.00 is identical with tesseractTrainer.py.

Features:

   - visual editor of box file
   - layout of symbol from box file reflect symbols on image
   - possibility to define bold, italic, and underline font
   - deleting, joining, splitting of symbols/boxes
   - easy and exact way of adjusting boxes
   - support for opening different image formats (tiff, png, jpeg, bmp, gif)
   - multi-platform support (tested on Linux 64 bit and Windows XP)

Buxfixes (in 1.01):

   - unicode support
   - opening of tesseract v3.00 box file (but save support only v2.0x box
   file)
   - identify/imagick is not need anymore
   - correct error that block to open file on Windows
   - solved issues regarding training symbols @ and $ (used also to identify
   bold and italic font)
   - workaround for missing Numeric support in PyGTK


Because IFAIK nobody react on Catalin e-mail I offered him to create project
to collect patches and possibly to solve known issues. Because of my low
time resource project is looking still for owner/contributors. Warmly
welcomed are expect for python (multi-platform) GUI (GTK/QT/wx...)
 because performance issues - on Windows XP (2GB memory) script crash or
freezes during opening file with a lot of boxes/symbols (e.g.
eng.arial.g4.tif), on Mandrivalinux 2010.164 bit (6GB memory) it take to
open&display 15 minutes!

Re: Announcement: new version of pyTesseractTrainer available

[zdenko podobny]

Hi,

your problem is that you use tesseractTrainer.py that was done in 2007 and
not pyTesseractTrainer.py (2010) that corrected this issue. I would suggest
to use
http://code.google.com/p/pytesseracttrainer/downloads/detail?name=pyTesseractTrainer-1.01.pyor
(if you are brave enough devel version:
http://pytesseracttrainer.googlecode.com/svn/trunk/pyTesseractTrainer.py).
In these case you do not need to solve problems that was solved already.

Anyway issues regarding tesseractTrainer.py/pyTesseractTrainer.py please
post to http://code.google.com/p/pytesseracttrainer/issues/list or
pytesseracttrainer-us...@googlegroups.com

BR,

There is new version (1.66) of leptonica [1] including precompiled windows
libraries. I copied
lib/*.lib from leptonica-1.66-win32-lib-include-dirs.zip to tesseract\lib
 and lib/*.dll to tesseract\ directory..

Than I was able to build Debug and Release version tesseract and
these commands work :-):

tesseract.exe phototest.tif phototest
tesseract.exe phototest.tif phototest batch.nochop makebox
tesseract.exe phototest.tif phototest nobatch box.train

This is first time when I was able to compile tesseract on windows and it
produce output :-). I have almost no experience with compiling sw on Windows
so it would be great is somebody can check this or provide better process.

Re: Tesseract Training Problem (under Mac)

[zdenko podobny]

Hello,

Tesseract 2.04 do not use "combined" file, so there is no combine_tessdata.
Just copy your files to tessdata directory.

At the moment http://code.google.com/p/tesseract-ocr/wiki/TestingTesseract
describe
training for Tesseract 3.0 (with mistakes ;-) - I started to check it so
soon there will be correct version). If you want to see description
for Tesseract 2.04 look at svn repository
http://code.google.com/p/tesseract-ocr/source/browse/wiki/TrainingTesseract.wiki?r=318.
It is in wiki syntax but it is easy readable.

BR,

Re: Alternatives to recompiling with libtiff?

[zdenko podobny]

Hi,

for conversion I use ImageMagick (
http://www.imagemagick.org/script/index.php) There is tool "convert"
with option  -compress.

If you need tool with gui you can also use IrfanView on Windows. During
saving of image you select option "Show option dialog" and than you can
choose compression type for tif.

BTW: Tesseract 3 will/has no problem (for me ;-) ) to OCR also other format
(png, jpg).

Re: FAILURE! box overlaps no blobs or blobs in multiple rows

[zdenko podobny]

Base on my experience: it is very difficult to train on scaned images that
you do not "create" (e.g. where you have no possibility to adjusts spaces as
described in
http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3#Generate_Training_Images
 )

In your case I would try to find similar font as on image and than I would
create training images with enough spaces to avoid ""FAILURE! box overlaps".

Re: Help on training tesseract for new language

[zdenko podobny]

First of all - alway specify version you use. Based on error I guess it it
3.00 (prereleae).
On linux I do not need specified TESSDATA_PREFIX (unless you want to use
other than standard tessdata directory).  I expect that you set
wrong TESSDATA_PREFIX.

Re: Help on training tesseract for new language

You wrote you compiled it. So I expect you know which version you compiled.

Anyway in version 3.00 on linux (not on windows) you can use "tesseract -v"
to see version.

Re: Tesseract 3.00 Released

[zdenko podobny]

create issue (http://code.google.com/p/tesseract-ocr/issues/list) but first:
1) do svn checkout (not svn update - I have experience from last week that
'svn update' could be tricky in same cases on windows but these problems
could depend on user experience ;-) )
2) be sure your VC++ installation is correct.

Released Windows installer (tesseract-ocr-setup-3.00.exe)

[zdenko podobny]

Windows installer for Tesseract-OCR 3.00 was released (
tesseract-ocr-setup-3.00.exe
).

Features:
- detection of installed Tesseract-OCR). Tesseract must be installed via
installer
- English language data are included
- Option to download other language data in installer
- Installer adapt PATH environment of current user (e.g. user that installed
tesseract)
- Installer setup TESSDATA_PREFIX environment variable for current user

Proposals for Tesseract graphics (logo, artwork) are welcomed.

This installer should be replacement for tesseract-3.00.win32.zip.
Also I would like to point part of README (
http://code.google.com/p/tesseract-ocr/wiki/ReadMe#General):

*The dll isn't properly working either. The BaseAPI is equipped with a
dllexport for Windows. I strongly recommend all new dll use to go through
the BaseAPI where possible, as this is most likely to keep working in future
versions as we move towards thread-safety.*

*
*
Unfortunately relevant files (tessdll.dll, tessdll.lib, dlltest.exe) were
included to tesseract-3.00.win32.zip package.

Credits:
Sergey Bronnikov - thanks for creating installer script and tests.

Best regards,

Zdenko

Re: 3.01 code

[zdenko podobny]

Just notice - if somebody did not recognize it yet:

in svn (http://code.google.com/p/tesseract-ocr/source/checkout revision 527)
there is 3.01 code that was build successfully on linux (Mandrivalinux
cooker 64bit) and Windows (XP SP3, VC++2008 Express). There is info about
additional 3.01 code coming from Ray in (near) future.

So please try it on other platforms/systems and report problem/submit
patches in http://code.google.com/p/tesseract-ocr/issues/list in Issue).

If you are willing to create C wrapper (see
http://code.google.com/p/tesseract-ocr/issues/detail?id=386
, 
http://code.google.com/p/tesseract-ocr/issues/detail?id=362
,
http://groups.google.com/group/tesseract-dev/browse_thread/thread/a348e5a6dbade5d7)
this could be good time for first version ;-) so it can become part of 3.01
final code.

This means that tesseract is not compilled against leptonica... Check you

Yes, check you instalation. Did you install also tesseract from distribution
(AFAIK Mandriva ships tesseract 2.04)? Try to run tesseract  including path
to avoid running wrong version.

Trainned data are in laguage files (e.g.  eng.traineddata in case of
tesseract 3.00)

If not,,what is the precise command to perform the training?

If you want to train language by youself, please read project wiki pages.

Re: what am i missing? tesseract runs but no output

[zdenko podobny]

Hi,

Just a quick reply:
I tried it on Windows XP with tesseract 3.00 and it produced bad result
(nothing usefull).

InfranView informations dialog showed that image has resolution 72x72 DPI ->
to low...
So I resampled  it (with Lanczos algorithm) from 100% to 300% size, set DPI
to 300 and decreased number of color to 16 (in InfranView because I have no
time to play with ImageMagick's options ;-) )...
Than OCR result was much more better with several mistakes (just quick
check)...

So with  several image improvements  you can get good OCR result.

BR,

Re: [Tesseract 3] English training text

I doubt that google will release their (full) training set :-(

Have a look at svn to file eng.cube.size [1]. You can see there name of
fonts that was training for English in 3.01. As far as I understood there is
(unpublished/not released) possibility to train language data directly on
font files. Unfortunately there are no detail for "cube" part of training.

Re: pixReadFromTiffStream: failed to read tiffdata

[zdenko podobny]

Hello Nicolas,

"Error in pixRead*" is error message from leptonica. Tesseract use leptonica
library for opening images. That mean if leptonica can not open file
tesseract can not *use *it.

So far there was ALWAYS problem with instalation of leptonica (if you got
this error). As suggested in these issues - build example leptonica progs
and test you image with them.

 I would like to point to one issue related to this: naming. If my findings
is correct this is current situation (please feel free to correct me):

Name of tesseract 2.04 library on Windows: tessdll.dll (tessdll.lib)
Name of tesseract 2.04 library for .Net on Windows: tessnet2_32.dll
(tessnet2_64.dll)
Name of tesseract (2.04?) library on Android: libocr.so (but maybe this is
issue only of https://code.google.com/p/eyes-free, because I think I so
somewhere libtess)
Name of tesseract 3.01 library for .Net on Windows: tesseractengine3.dll
Name of tesseract 3.01 library for python (created with SWIG) on Linux:
_tesseract.so
Name of tesseract 3.01 library on Linux (as mentioned by
Jefferey): libtesseract_api.so.3.0.1, libtesseract_main.so.3.0.1,
libtesseract_ccstruct.so.3.0.1, libtesseract_neural.so.3.0.1,
libtesseract_ccutil.so.3.0.1, libtesseract_tessopt.so.3.0.1,
libtesseract_classify.so.3.0.1, libtesseract_textord.so.3.0.1,
libtesseract_cube.so.3.0.1, libtesseract_training.so.3.0.1,
libtesseract_cutil.so.3.0.1, libtesseract_viewer.so.3.0.1,
libtesseract_dict.so.3.0.1, libtesseract_wordrec.so.3.0.1,
libtesseract_image.so.3.0.1 (libtesseract_api.a,  libtesseract_main.a,
libtesseract_ccstruct.a,  libtesseract_neural.a, libtesseract_ccutil.a,
 libtesseract_pageseg.a, libtesseract_classify.a,  libtesseract_tessopt.a,
libtesseract_cube.a,  libtesseract_textord.a, libtesseract_cutil.a,
 libtesseract_training.a, libtesseract_dict.a,  libtesseract_viewer.a,
libtesseract_full.a,  libtesseract_wordrec.a, libtesseract_image.a)

I believe it would be good if we can agreed on "naming standard".

Re: Tesseract compilation on code blocks (gcc + mingw)

[zdenko podobny]

Hi,

I tried (as excercise ;-) ) to use cmake (http://cmake.org/) for building
tesseract, because it would enable to use one build system on more
platforms. I have first version (not very sophisticated :-) ) that works on
linux (with gcc) but I failed on windows with mingw. Problem is that minwg
miss at least one function that is used by tesseract - 'strtok_r' (see
http://sourceforge.net/tracker/?func=detail&aid=2673480&group_id=2435&atid=352435).
I have no time to play with porting and testing (or using external
library pthreads-win32) if there is other working solution (VC++2008). cmake
support also Visual Studio 6-10 but I did not try it yet (cmake is not my
priority).

Re: tesseract.exe has stopped working on win2008 r2

[zdenko podobny]

Hi,

tesseract is command line tool. Item i windows menu is more or less just for
testing purpose (it will not be present in next version of tesseract
installer).

If you need gui have a look on Vietocr, PDF OCR X, lector etc.

convert it to png - you got smaller picture with the same quality and
tesseract should process it without problem.

This is not tesseract but leptonica issue (library used for image handling).
When I run it on linux I got error message comming from leptonica (1.67 -> I
did not try 1.68 on linux yet):
Error in pixReadFromTiffStream: spp not in set {1,3,4}
Error in pixReadStreamTiff: pix not read
Error in pixReadTiff: pix not read

On Windows leptonica "release version" library did not show error/warning
messages because of compile option "NO_CONSOLE_IO" (see
http://code.google.com/p/leptonica/issues/detail?id=42).

It looks like leptonica did not support lzw compression for tiff ( see
http://www.leptonica.com/source/README.html  "9. Image I/O" - lzw is
mentioned in png and gif section, but not with tif). I change
tif compression from lzw to zip (BTW: this will cause smaller image),
tesseract will produce ouput (on XP SP3).

Have a look on VietOCR (http://sourceforge.net/projects/vietocr/) there is
also "screenshot" mode that try to solve this problem (yes it work also for

[zdenko podobny]

Tree different users with working tesseract-ocr have problem with this
input. Isn't it sufficient for you? Yes there could be other issues related
to Windows 7 (because official build was done on 32bit Windows XP), but
without solving "input issue" other investigation will
be unnecessary difficult...

Incorrect:

   1. image support is task of leptonica, so list of supported format can be
   found of leptonica web and source code. I think we really need to
   distinguish this, because with upgrading of leptonica there could be support
   for new format without changing a line in tesseract code.
   2. I guessed that leptonica has problem with tiff with "lzw compression".
   When I created tiff with "zip compression" it worked (there are also
   other compression algorithms available in tiff: Packbits, G4, G3,...). I
   never said that leptonica (tesseract) support only uncompressed tiff. I am
   sorry if I was not clear about this.
   3. As TP corrected me: problem is not in LZW compression, but in "Samples
   per Pixel". Leptonica support 1, 3, 4. Input image used (unsupported) 2.
   To "solve" this just open input file in InfranView and save it as tiff with
   lzw compression. It will change "Samples/Pixel" to 1 automatically ;-)

Re: Problem with Tesseract 3.00

[zdenko podobny]

Hi,

unfortunately some fixes regarding windows build was committed after
releasing 3.00 version (=revision 498).

I thought about 3.00.1 release (=revision 525) and as "temporary solution" I
created 3.00.1 tesseract.exe (somebody ask for it). Than I changed my mind
because it looks that developers grab the latest svn version with fixed
issues...

So I suggest you to use svn version (revision 525 or 578 if you want to test
3.01 version).

Just from my bookmarks (have-a-look-on-this-later ;-)): there is
project COSI - The Common OCR Service Interface [1] that used patched
tesseract-ocr 2.04 in server mode. I did no test it yet, but maybe it would
be good start point.

Your posts indicate that you moved tesseract to other place (e.g. you broke
your installation). Now you blame tesseract ;-)

You get error "Error openning data file" it means that it can not find
requested data file because of:

   1. TESSDATA_PREFIX point to "wrong" place - you can check it in command
   line (after you received this error) with command:
   echo %TESSDATA_PREFIX%
   2. TESSDATA_PREFIX points to correct place, but the file did not exists.
   You can check it by command:
   dir "%TESSDATA_PREFIX%tessdata"

There is report that if you change/remove TESSDATA_PREFIX (via regedit or
via My Computer -> Properties ->...) there is need to restart computer. If
you need to change it just for opened command line session, you can do it
with command:
set TESSDATA_PREFIX="your desired path\"

Re: Build files for the Tesseract OCR for android (Windows Xp)

[zdenko podobny]

Hi,

the commands mentioned in README are very simple that can be replaced by
other windows program (e.g. unpacking) or by gnuwin32 tools. If you can not
do it by yourself, that I really suggest you invest your time to something
else. You will face much more difficult tasks e.g. as far as i know nobody
was able to build tesseract on windows with gnu tools.

Re: Difficulties to use Tesseract

[zdenko podobny]

Hello,

I use tesseract on Mandrivalinux without problem. But I compiled it by
myself ;-) I am not satiffied with packages provided by Mandriva team ;-)
e.g. they included tesseract 3.00 to cooker but without English language
data, they did not include leptonica library, that is used for image
handling...)

If you are able to compile software by yourself than try the latest svn
version [1]. Do not forget first install leptonica [2] ;-).

Did you recompiled tesseract? Can you send your out.tiff? (search forum for

Nothing is wrong ;-) If you did not speciefied language (with -l option see
[1]), tesseract used default language: English. And as far as I know English
uses  Latin character only. So try to add  '-l kor' to your command (but do
not forget to install [2]).

As far as I know tesseract do not care about system language.

General rules are written here [3]. I suggest to follow them closely. Have a
look on provided boxtiff files [4] for spa, eng, deu, ita, fra, nld as
examples.

There was aim for automatic training [5], but when the project
(tesseractindic) moved to gihtub I can not find the folder
(tesseract_trainer) in source code anymore.

Last advice: share your experiences with others ;-)

Re: creating train data set for Korean

[zdenko podobny]

Oleg,

Are you sure with message? "tesseract.exe" indicate that you are using
Windows... (I am not aware that any official linux build system create
'tesseract.exe') But part error message ('/usr/share/tessdata/') indicates
that you are in linux (or unix like) environment...

You wrote that you installed 'tesseract-ocr 3.0 on Windows 7'. But error
message indicate that you are using tesseract 2.0x. E.g. when I tried
tesseract 2.04 (on windows XP):

t204\tesseract.exe annyong_eng.png annyong_eng -l dummy

I got message:

Unable to load unicharset file C:\Program
Files\Tesseract-OCR\tessdata/dummy.unicharset


If I try tesseract 3.00:

tesseract.exe annyong_eng.png annyong_eng -l dummy

I got message:

Error openning data file C:\Program
Files\Tesseract-OCR\tessdata/dummy.traineddata


How did you install tesseract?

Re: Deskew waves in a document

[zdenko podobny]

Hi,

I am not sure if I understood your problem (e.g. if you are looking for
 "dewarp" ("straighten text line") feature. In leptonica there are example
programs for dewarping: dewarp_reg.c and dewarptest.c. I try it to on one of
my project, but it did not worked on my images (e.g. I plan to play with it
later ;-) )

On  http://diybookscanner.org I found references for (commercial) program
Book Restorer [1]. I had change to test it and I can proof it worked perfect
- if you need to straight text lines in output.

I have experience only with these. But if you google for "dewarp" or "Image
straightening algorithm" you can find a lot of interesting suggestions
for algorithm or programs ([2], [3])

There is written that font_properties is required for 3.01 (e.g. you do not
need to use '-F font_properties' for 3.00, but you need to use it for 3.01.

BTW: 'mftraining --help' will show other options for mftraining

If somebody is really interesting she/he can know answer ;-). Within 1
minute ;-) ([1] [2] [3]). BTW: there is Developers

There were several requests for training data (in forum, in issues). I did
it too. There was no official reply to such requests. AFAIK Google is
not obliged to release them. So I guess they have a reason for not providing
them.

On other hand this could be opportunity for tesseract community :-): to
create alternative training set. As Ray mentioned ([3]) they use "more
automated training process based on rendering text from fonts", so training
base on "real world" scanned documents could be interesting (but more
difficult)

Re: can't compile tesseract on win7 with visual C++ 2010 express

[zdenko podobny]

Hi,

It is written on main page: supported platform is Windows (x86/32) with
Visual C++ Express 2008 [1]. As I heard it is not a big problem to compile
VS2008 project files (in directory vs2008) in VS2010  ;-)

In svn version there is also initial support for VS2010 (directory vs2010)
created Michael Lutz. But there are some issues that need to be fixed (e.g.
debug version is not working at the moment - release version should be ok).
SVN version should be used by developers...

Because I still use VS 2008 (= I can not help with VS2010 issues) - patches
and improvements for VS2010 are welcomed.

Re: Create traineddata from different tif and box files

[zdenko podobny]

Hi,

Problem is that you use the latest version and you do not read the latest
manual [1]. If I correctly understood that German manual (via google
translate), it is for version 3.00 so it do not follow changes in 3.01
version.

Another "problem": 3.01 is not released yet. It is for developers and
experienced tester for testing and bug reporting. IMHO 3.01 training is not
fully documented.

 Maybe Jimmi will update it for 3.01 :-)
Some good information could be found in tesseract forums.
All links are on main project page. Surprisingly ;-)

Re: Create traineddata from different tif and box files

[zdenko podobny]

It it written on training doc[1]:
"*…**each .tr filename must match an entry in the font_properties file, or
mftraining will abort.*"

So you could save your time if you read documentation.

Re: Building Tesseract with VC2008

[zdenko podobny]

Hello,

leptonlib* is leptonica library. You can download it (version 1.67) from
http://code.google.com/p/leptonica/downloads/list.

Or grab the latest svn version of tesseract (leptonica library is there).
There are solved also other issues...

Re: Creating DLL for tessract3

[zdenko podobny]

Please read ReadMe [1]

Unfortunately tessdll was not removed on time from source so it became part
of source code released as version 3.00. But it is not working. Have a look
on and search tesseract-dev forum [2] there for 'tessdll' and maybe for
'wrapper' have a better overview).

Look on AddOns wiki [3] - maybe something will work for you...

Hi,

at the moment only Visual C++ Express 2008 (it is for free) is supported on

As Dmitri pointed out: Error message say you use wrong (not 3.01) config
file. see [1] - parameter "*tessedit_use_nn*" was removed from config file
'box.train' in revision 526.

So update your box.train file to recent version.

Re: "Error opening data file ./tessdata/xxx.traineddata"

[zdenko podobny]

AFAIR this error means that version of tessdata file(s) (xxx.traineddata) do
not match version of tesseract.
Check if you have 3.01 data files (traineddata) in tessdata folder.

You code (configs) is not actual - I already mentioned it list [1] or
your TESSDATA_PREFIX point to wrong directory (directory with old configs).
