Hi,

I just wondered if anyone had used any OCR software - you know, something that can take a scanned document and produce an editable text version.

In particular, does anyone know if you can link such software to a Portuguese dictionary, or at least to the Portuguese alphabet/accents - the one I've tried only "knows" English and has great difficulty with all the words ending with "-ções" for example.

Thanks,

Steve

PS - I don't want to have to pay for it :D

This is something I have considered myself but not tried

My HP printer scanner comes with OCR software.

Reading the instructions you can scan a document in any language and convert it to a text document in that language regardless of your operating system.

Therefore it should be possible to scan a Portugese document then turn it into a Portugese text document.

Next copy and paste into an online translator and hey presto original converted to English

I think :oops:

Yes, Fred, that's the idea. The trouble with the one I'm using is that it doesn't recognise the Portuguese accents and other common combinations of characters (de and em for example) which means there is a lot of correcting to do by hand before I can translate it.

I know there is always some correction needed, but I'd like the software to make a better job of it first-up.

With further playing I've sorted out a combination that seems to work (for me at least). I've found a free program - FreeOCR - that you can use along with a language module specific to Portuguese.

Download the program from http://www.freeocr.net/

Download the Portuguese language file from here (Brazilian Portuguese unfortunately)

This will download a packed/archive file which when you unpack it will give you a series of files beginning with "por." - unpack these files into the folder c:windowstessdata

Then, when you run the FreeOCR program, you should be able to go to the "OCR Language" option (top right of the screen) and select "por".

Once you have a scanned image of the page (using whatever scanning software came with your scanner; at ideally 300dpi), you can load this image file into FreeOCR, select an area to interpret, and then save the resulting editable text file either as a plain text file or export it into MS-Word. And of course, once you have the text, you can run it through Google for a rough translation.

You may have to tweak the file a bit, especially if the original page is creased or blurred, but it recognises all the accents, it even gets the little ° symbols that "officialese" Portuguese uses all over the place.

I have TextBridge but have only ever used it once. Waste of money that was :D

My Epson scanner also has text scanning built in but I don't know if it's any good.
