Ocr

[manolomanolo]

Hi to all.

I am trying to run any OCR application in Ubuntu but I have not been lucky.

I've tried to follow this guide:
http://ciaolinux.myblog.it/archive/2...con-xsane.html

with no luck. It explains how to do using xsane and gocr/tesseract.I am unable to install xsane2tess and I get the following error:

sudo dpkg -i --force-architecture xsane2tess_1.0-1guadausers1_i386.deb 
dpkg: warning: overriding problem because --force enabled:
 package architecture (i386) does not match system (amd64)
(Reading database ... 229257 files and directories currently installed.)
Preparing to replace xsane2tess 1.0 (using xsane2tess_1.0-1guadausers1_i386.deb) ...
Unpacking replacement xsane2tess ...
dpkg: dependency problems prevent configuration of xsane2tess:
 xsane2tess depends on tesseract; however:
  Package tesseract is not installed.
dpkg: error processing xsane2tess (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 xsane2tess

Both tesseract-ocr and tesseract-ocr-ita are installed. No "tesseract" package is in the repos.

Any suggestion, please?
Thanks.

Ubuntu 10.04 64 bit

not sure exactly what you are trying to do with OCR, but I've always found "gscan2pdf" to be a nice GUI application for scanning documents. However Tesseract isn't a very good OCR program, commercial OCR applications are typically better.

sudo apt-get install gscan2pdf

might be a better solution for you and should be easier to install.

why not use pdfocr? it works fairly well and it *very* easy to use

From the looks of it, he's scanning documents to OCR, so using gscan2pdf will most likely remove a few steps by allowing him to OCR as soon as he scans

thanks for your replies.

I have been using gscan2pdf with both the gocr and tesseract engine but the result is very very bad.

On the other hand, pdfocr produced an output very similar to the input, the only difference is that the text is selectable. i can copy it but it pastes something other than the real words.

May be those programs are not useful with text hand written?

like I said, Tresseract (and gocr) arn't that great, they have a hard enough time with text from books and stuff. Even high grade commercial applications have a hard time recognizing even very neat handwritten notes.

I did some work setting up OCR hand written form processing in the past, we had to write some logic challenges into the programs to verify the data,
(for example: if (DOB_Month > 12) || (DOB_Day > 31) || (DOB_Year < 1900) then flag for review)

also, the if the OCR programs confidence wasn't that high, it would flag it for review itself.

One of the best commercial OCR applications out there (IMHO) is ABBYY FineReader (or their other applications) but unfortunately as far as I know they don't have a linux version. And it's pretty expensive ($400 for the full "Professional" version, but they have an "express" version for $50)

Try cuneiform - I use it for several months and am quite satisfied with it. It's a terminal application and it is in Ubuntu repositories.

Has anyone got Abbyy FR 9 to work under wine? I use VirtualBox but I am using Win2K so I can not update to FR 10.

Lios is a free and open source software for converting print in to text using either scanner or a camera, It can also produce text out of scanned images from other sources such as Pdf, Image or Folder containing Images.
