Update:

I have installed tesseract-ocr 3.02 on my PC and have also started training it for sanskrit (and hindi) usiang sanskrit2003 font. Recognition seems to be font-specific and will require training for additional fonts for it to work well on scanned pages.

Some questions:

Which Unicode devanagari font or fonts do you think most resemble the typeface used in old scanned sanskrit/hindi/marathi books? If I train for that font, it will improve accuracy of the scanned pages.

Are there any sample pages/small booklet in .tif file format from DLI or other sites that I can use to test? Any volunteers for proofreading the output?

The software also uses a wordlist (dictionary) that can be used to improve recognition. Is it possible to get a list of more common words or maybe just nouns and adjectives and verb roots from the sanskrit dictionaries? The list should be in unicode devanagari - one word per line.

Regards,

Shree

Never used it though. I will be interested to know how it goes in case anyone uses it.

I had made some link updates in FAQ.  There is a reliable OCR from Hellwig but at relatively hefty cost.  Search for OCR in FAQ.

Sai's friends are supposed to be working on it but no word about it from him or anyone for long time.  I guess it is staying in their wishlist.
I have CCd to Sai, let us see what he has found so far.  I am CCing to Vishvas Vasuki and Arun who are also somewhat tracking its progress.

Subject: sanskrit ocr

 

Ram ram, Nandu,

 

Any updates on any open source sanskrit OCR?

 

I saw a link for ocrlib at https://code.google.com/p/ocrlib/

but last update is from 2010 and it seems limited to mac os.

 

Tesseract seems to have made a start for Hindi - I installed hindi files with vietocr.net - just trying out right now.

 

Do you have any feedback regarding these?

 

Thanks,

Shree

Hello विश्वासो वासुकेय ,

Actually I don't have knowledge of sanskirt. But I am a web developer, How can i help you. I program into PHP and little bit java.

[विश्वासो वासुकेयः (Vishvas Vasuki)]

Thanks for reaching out Vishnu. May you soon learn the simple and beuatiful language of the ancients.

I don't have any Java/ PhP project in mind right now - will ping you if I do (perhaps shree devi has suggestions.).

In case you are open to learning about dictionary formats (stardict, http://en.wikipedia.org/wiki/Wordnet )  and mobile dictionary programs (esp goldendict), I had a suggestion. Let me know if you are interested.
