I'd like to scan a good amount of papers I have lying around, with the least possible hassle. I would like to convert them to images using Simple Scan, then convert them to text using OCR. Is there a good OCR app with a GUI that will give me good results at the push of a button?

  • GOCR Install gocr is an OCR (Optical Character Recognition) program.It converts scanned images of text back to text files.
  • CLARA is another good graphical option.
  • OCRAD Install ocrad is an OCR can be used as a stand-alone console application,or as a backend to other programs.
  • KOOKA Install kooka is a KDE application but works fine,in addition you have to install actual OCR programs like GOCR and OCRAD.After installing Kooka and the OCR programs,you have to point Kooka to the OCR install location in order for it to be able to convert the JPEG to text.
  • OCRFeeder Install ocrfeeder is a document layout analysis and optical character recognition system.
  • Tesseract Install tesseract-ocr is Command line utility and it is very simple to use.You can install language package tesseract-ocr-eng Install tesseract-ocr-eng

Have a look at this page.

Note:
To run tesseract goto terminal and type the following

tesseract imagefile.tif outputfile.txt

Tesseract can only read a TIFF file - if you've got a JPEG or PDF or whatever, you'll have to convert it. Also, the filename extension must be .tif, not .tiff, otherwise tesseract errors out.

If your spoken language isn't English? is any extensions for other language? –  Vassilis Dec 5 '10 at 11:30
    
karthick, that was a great answer. Could you please add some info on OCRFeeder to mark it as the accepted answer? –  Bou Dec 5 '10 at 11:31

@Vassilis: OCR systems are language independent because they recognise characters, not words. However if your alphabet has not-Latin1 characters ( like cyrillic ) then it may miss those. –  OpenNingia Dec 5 '10 at 11:41
    
Some times I need to convert images with none English text (Greek), is any extensions to read the Greek letters, with this programs? –  Vassilis Dec 5 '10 at 11:42

disclaimer - I am closely connected with the development of this opensource solution

Lios can convert print 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.

Program is given total accessibility for visually impaired.

Since I'm closely connected - I would love feedback.
