OCR In Linux

OCR In Linux

[John J. Boyer]

Hello,
I believe that sometime ago there was a discussion of OCR packages that
would work with Linux. Now that I'm getting into Linux in a big way, I would
like to have that information, including how much these packaages cost.
When I boot my Redhat Linux, it says it is initializing the USB controller.
I have a USB scanner. Can't remember the name now, but is there a chance
that I could find drivers for it?
Thanks.

There's a chance you already installed those drivers.  Try man sane and
see what happens if you have red hat.  If you have another flavor, I think
you can download and install sane from the web.  This will at least run
your scanner, I don't know that it'll do ocr.

a quick google search turns up at least four:
   clara OCR:  www.claraocr.org
   GOCR: http://altmark.nat.uni-magdeburg.de/~jschulen/ocr/
   a commercial OCR with a linux version: www.vividata.com
   a commercial OCR with a linux version: www.mentalix.com

try SANE (Scanning Access Now Easy): http://www.mostang.com/sane
  (note: site is down at this time due to @home belly-up)
  (note: SANE is shipped with most modern linux distributions)

another quick google search turns up one possible USB scanner resource page:

Have to check this one again.

Wroks quite fine, but don't expact miracles like tables andso-on.

WAY TOO expansive, besides it's too graphical as well.
And it does all kinds as ROOT which you don't have control voer, so I don't
like it.

Never heard of.

	Since this topic has come up, I have a few questions.  Do
any of the free OCR packages run in command line mode?

	I don't mind that they may not automatically turn the
image for you to take care of upside down pages, etc, but how
does the quality of the conversion compare with something like
OsCar or Reading Edge?  I have found those products to do a
pretty fair job on standard printed pages or typewritten
material.  If I could duplicate that functionality in Linux, I
would be happy as the OsCar system I use here at work is
approaching 9 years old and the HP scanner will probably crash
and burn one of these days.

	It is my understanding that you do the OCR under UNIX by
scanning a Jpeg image with the scanner and then feed that image
in to the OCR program where you get a text file or standard
output if text can be decoded.

	If the output indicates differently when tables or
columns are involved, one should be able to write filters in C or
perl or even awk to read them more easily.

Is there any cheap reading edges around that work good? Or are they even
being made any more? I know computers have come a long way towards
integrating such functions in, but I like the idea of dedicated machines,
as they're smaller, and usually do their function real well as that's all
they must do. Figured $5000 is pretty expensive, and maybe facing the
possibility of only having my laptop to use means no numpad, and the need
to add it on and take more space, where the dedicated all-in-one device
could fit away some where and I could get it out and plug it in when I need
it.
