I think 'fas' is the language code for Persian.

[Hossein Razizadeh]

It seems 'fas' is for Persian, but there are no cube files, resulting in poor results. Arabic language files work much better for Persian images. There is another 'per' folder for Persian, but there isn't even '.traieddata' file for it. Does anyone know if 'Google Doc' has used 'Tesseract' for its OCR engine? Google Docs performs OCR for Persian images with good accuracy!

Ray was looking for comparative feedback regarding the new traineddata for RTL languages, so this will be useful.

As far as I know, Google Docs does not use tesseract OCR engine for recognizing the text. Its OCR accuracy is better than Tesseract for some Indian languages also. However, it doesn't seem to handle tifs, and processes only first 10 pages of a pdf.

Interesting. Can you please clarify source of your knowledge?

Another caveat worth noting is that I only tested a small fraction of these languages - maybe 25?

I suspect, for instance, that all the Arabic-based langages except ara don't work very well.

I would be interested in an more feedback on how bad it is in any of them, and will take suggestions into account for the next version after 3.04.

I think the problem is the lack of cube files in persian. Does anyone know how to add cube files to be used by tesseract? There is a 'fas' folder in 'langdata' that contains some cube related data, but I don't know how to use it with tesseract.
