OCR of Devanagari + Diacritics + English

[Alexander Gribanov]

Hello!

Finally got real project for OCR.

Could anybody please give some advice in the process step by step, how do I make OCR for such pages?

https://drive.google.com/file/d/1Wdm4_tZHWHeVFlF7ND83xtvL29OCdTY_/view?usp=sharing

Do I need to split pages manually before the OCR to different type of the blocks?

What command to use for OCR?

Thank You all very much in advance.

I recently was able to write a notebook to read a page of single column Sanskrit and English and run through tesseract to OCR both languages 

I will take a look at your file and create a colab notebook sometime today or tomorrow

Try http://ocr.sanskritdictionary.com/

For OCR of Devanagari + Diacritics + English

It's Google option gives better result than tesseract

Here are the results and linked below is an example notebook for you to get started with.

Code is self explanatory, and can be adapted by you. You will need to improve on many things,

but here is a start. Please let me know if you have any questions.

Please feel free to share some improvements, which you can.

Thanks

The normal paths of spiritual knowledge cannot reveal his secret and favourite pastimes. The pastimes within Vraja are incomparable and can only be perceived through total surrender to Him. ब्रह्य मे दूढ्यो पुरानन गानन । वेद रिचा सुनि चौगुने चायन ।। Cel GA Hae a fads वह केसे सरूप अरु कैसे सुभायन । टेरत हेरत हारि TEM | रसखानि बतायौ न लोग लुगायन । देख्यो दर्यो वह कुज कुटीर में बेट्यो पलोटत राधिका पायन ।।

That is a beautiful app.

Shree Devi Kumar, what service does the 'google' selection hit? Is it free?

I split the pages to left right pages and posted on the ocr with google option and here are the results, I have not compared yet but couple of observations,

1. yes google ocr captures diacritics!

2. tesseract retains line breaks but google ocr provides flowing text, which is great

3. Tesseract is waylaid by the decorative images, trying to understand them as text, google ocr skips them, nice

Thanks for the pointer

ब्रह्म में ढूँढ्यो पुरानन गानन। वेद रिचा सुनि चौगुने चायन।। 
देख्यो सुन्यो कबहुँ न कितहुँ वह कैसे सरूप अरु कैसे सुभायन।। 
टेरत हेरत हारि पस्यौ। रसखानि बतायौ न लोग लुगायन। 
देख्यौ दुर्यों वह कुंज कुटीर में बैठ्यो पलोटत राधिका पायन।।

I have been searching for the supreme Brahman in the Puranic songs and from listening to Vedic verses my desire to meet Him has increased four-fold; 

Never and nowhere have I seen or heard of His Form and His Nature; 
Rasakhan says "I have completely failed to find Him despite calling to him and searching. Neither man nor woman has been able to tell me where to find Him" But then I beheld Him afar, sitting in a secret love bower, massaging Sri Radhikajus Feet. (2)

Yeah, looks great, but still there are some mistakes by Google...

I'm not sure, as long as I heard, Tesseract could be trained, but I never heard about that Google service, so not sure, is it possible to reduce such problems via some more trainings?

I mean, does the Google service is trainable actually?

Ok thanks for the share very nice interface

As Alex highlights tesseract allows further customization

I myself want to learn how to train tesseract for Tamil and Sanskrit using your scripts and guides but haven’t got a good starting point yet

That site works for other languages also, though it is not specified explicitly.
