How to use tesseract ?

[grandMOJ]

Hello,

I'm interested in this software, but I still don't know how to use it
on Windows. I tried to find the answer on the web, but I failed.

Could anyone explain me the complete command-line, with all the
options (what I want to recognize is really hard), or give me a link
to a page which contains the very basic documentation, unavaible on
the FAQ ?

Thanks a lot.

First, thanks a lot for answering.


So, to synthesize, that's my situation :

The tesseract folder is located on "C:\Program Files (x86)\Tesseract-
OCR", and the (.exe) path is "C:\Program Files (x86)\Tesseract-OCR
\tesseract.exe". The picture I have to submit in order to an OCR test
corresponds to "C:\Utilisateurs\Al-Fares\Bureau\test.tif". The output
containing the results may be a text file (I don't know the
modalities...).

Working with Windows7, when I press [win + R] I get the "execute"
interface, in which I can call a program with the appropriate command-
line. There, what do I have to write ? Something like :
"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe" [arg 1] [arg 2]
[arg 3] etc.

Could you please customize the command-line with my personnal
settings, in order to really make it work ? I tried those :

tessetact.exe "C:\Utilisateurs\Al-Fares\Bureau\test.tif" output -l
tessetact.exe C:\Utilisateurs\Al-Fares\Bureau\test.tif output -l
tessetact.exe "C:\Utilisateurs\Al-Fares\Bureau\test.tif" output -l
lang<http://code.google.com/p/tesseract-ocr/wiki/
TrainingTesseract3tessera...>
tessetact.exe C:\Utilisateurs\Al-Fares\Bureau\test.tif output -l
lang<http://code.google.com/p/tesseract-ocr/wiki/
TrainingTesseract3tessera...>

All gave nothing interesting.


I'm very grateful that you decided to help me.

I do not have tesseract at my new pc and now i am on it.

 

But i can say something:

 

I am not sure if "win+R" provides an interface to run tesseract.

 

But i can advise you to "win+R" , type "cmd" in that little "win+R" window.

 

When you write "cmd" and enter, command line utility of windows 7 opens. A little black window.

 

In that window you will probably see

 

C:/Users/Your User Name>

 

You can type "cd.." to climb upper directories. You can "cd aDirectory" to move in.

 

Thus you must first "cd .." for several times to move up to pure "C:/"

 

Then to move in to C:\Program Files (x86)\Tesseract-OCR

 

by

 

"cd Program Files (x86)"

"cd Tesseract-OCR"

after all now you can

 

tessetact.exe "C:\Utilisateurs\Al-Fares\Bureau\test.tif" output -l eng

 

 

you must specify a language after "-l" parameter as i remember, like eng at the above command,

 

If you think to train tesseract for your own language you must do a training with the directions in the link i wrote before.

********************************************************************************
You can go through this given site if you already install tesseract s/w...
http://tesseract-ocr.googlecode.com/svn/trunk/doc/tesseract.1.html

or you must first install the tesseract s/w through the below sites:
1. https://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-setup-3.02.02.exe&can=2&q=
2. http://sourceforge.net/projects/tesseract-ocr/

after installation run this s/w through command prompt like :

Suppose you installed this s/w in a folder in c:/tesseract(folder).
take any image say abc.tif in the same folder then in command prompt you give command:
cd/
cd tesseact
cd tesseract abc.tif out

it will make a text file in the same folder in the name of out.txt with the content written in the image.
Hope this will help you.

I've installed Tesseract by using Windows Installer and after going through the steps mentioned above I get following error in cmd.

Tesseract Open Source OCR Engine v3.02 with Leptonica

Empty page!!

Empty page!!

Here's a screenshot of my error:

Version of Tesseract is 3.02.02.

I'll be really grateful for the help.

Hi Sheekha,

It would be more useful if you could attach the sample image that
causes that.

Have you looked at this page?
https://code.google.com/p/tesseract-ocr/wiki/ImproveQuality

It's likely your problem is caused by one of the issues mentioned
there.
