[Feature] Optical Character Reader [OCR]

[shreekrishnaacharya]

Can we also add Optical character reader in this application for reading student names and other detail?

[Udayraj123]

Yes, we have a related issue to add a plugin for the same. Can you help me formulate the problem with more clarity?

We need help in generalizing the approach.

Hello, I can clearly contribute to this issue. As I have many a times worked upon tesseract OCR, Vision API OCR, and Microsoft OCR wherein I had made changes in the OCR by computer vision techniques like gray scaling the image and even giving it proper contrast to read the text accurately.

Thank you Adwait01. i am also working on this OCR part and would appreciate your part of contribution. actually i am working on my thesis and i need to read document that consist of Mark and some text character. Your contribution would be very helpful. Also is it possible to detect cross mark and remove them from image or replace them with white.. as this would be helpful to remove wrong mark on answer options. Thank you

Hi @Adwait01-Bhosale, that's great to hear! Can you and @shreekrishnaacharya join on over discord and discuss possible solutions with me?

[Udayraj123]

Here is a related issue for which I have framed a solution - https://github.com/Udayraj123/OMRChecker/issues/73

Just like extracting text from an area, that issue requires extracting passport photo from an area (using page cropping)

https://github.com/Udayraj123/OMRChecker/issues/99#issuecomment-1328764312 @Udayraj123 , @Adwait01-Bhosale my discord account is sksharma72000 . I have worked on tesseract OCR, it can detect printed text well however it is not suitable for handwriting detection.

[Udayraj123]

That's fine for a start. I have a requirement from a business regarding the same. You can help read printed roll numbers or booklet numbers in an area on the image. Later we can scale it for handwriting detection
