It appears you are looking for OCR software.  

Ubuntu has a few:

Once the file has been converted to text, you can then edit it.


On the other hand, if you're looking for image editing software, take a look at gimp.

Best of luck.

I'm not sure what you're looking for.  

Text and images are two different things in their data structure and how they are handled.  In order to edit images, you have to use an image editor.  Editing text from a scan is a bit more complicated.  The scan comes in as an image.  In order to edit the text portion of the scan, you must first convert it to a text format.  Which is what the OCR software does.  You can then edit it like any other text document.

Now, if you have a scanned document that includes both text and pictured, the OCR software will recognize the text and leave the images as individual images within the newly created text file.  You can then edit the text with a text editor (or OpenOffice).  If you wanted to edit the images, you could save them, edit them, then put them back in the converted file.

Does that help explain?

It's really explained me. I was having the doubt that what if the document has both images and text and it's cleared it now. I'll give a try of the software and let you know

Could you recommend me any best gui tool from them. I know about gimp and I'll be using it for editing images but I didn't try editing scanned documents.

As far as OCR software, in the ubuntu community link I gave above, take a look at OCRFeeder.  It runs in a gui.  Although it doesn't have character recognition itself, it does have predefined settings to use Tesseract for character recognition.

Once you have the characters recognized the document can not be edited using any text editor.  OpenOffice www.openoffice.org can be used on ubuntu for this.
