Tesseract Training Problem (under Mac)
OCR Newbie
Currently I am trying to use Tesseract(2.04) to recognize my own data,
with Mac OS X Snow Leopard.
I find this http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract
and I am trying to follow this tutorial.
My questions are:
1. I already have my train.tif ready, but I am not sure where I should
place the image file, (under 'tessdata' folder or can be anywhere?
2.About run the tesseract on my training image, it asks to run
'tesseract train.tif train batch.nochop makebox' , I guess I should
use the terminal, but when I type this command into it, it keep saying
'tesseract command not found', I tried to run the configure terminal
first and type 'make', but it is still not working.
Can anyone give me some instructions on how to run this, specifically?
I am sorry I am totally fresh to the Mac OS.
Any help is appreciated!!

If you're running 'tesseract train.tif ...', it just needs to be in
the current directory.

You also need to use 'make install', or provide a path to the
executable - Unix-like systems (unlike DOS, etc.) do not include the
current directory in the executable search path. (You can, of course,
change that but it's A Bad Idea.)
If tesseract is in /home/jim and $PWD (use 'echo $PWD') is /home/jim I
could use:
./tesseract ...
('.' means 'this directory')
/home/jim/tesseract
(the full path)
or even
../jim/tesseract
('..' means 'one level lower' - in this case, '/home')
or even:
$PWD/tesseract
($PWD is an environment variable, and will always be there... unless
you remove it from another shell, but you probably don't need to worry
about that).
I think MacOS uses /User or something else, just substitute with
actual values. Using 'make install' will be more convenient, though.

Thank you so much for the reply.
I just have one more step to make, I am using Tesseract 2.04 now and I've got all the files ready, I am trying to combine them all together but there is no combine_tessdata for 2.04, I want to know how to combine them under 2.04.
Thank you so much!!

So details for training are split to 2 wikis:
http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract2
http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3
Unfortunately comments (now irrelevant) stay on http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract ;-)

Yeah. Unfortunately, I'm not aware of any means of deleting comments.
