Hello, @Obul5750

I have investigated provided files.
I have noticed that reference points (black squares on the corners) are added on already scanned image. Unfortunately, it is not possible at the moment to recognize such image.

Aspose OMR require template to be generated using a .txt\json\C# markup.

Generated template will produce template image with reference points(black squares) and .omr files containing detailed information about template layout.

This .omr file can be used later on to recognize multiple scans of the filled template.
There is a more detailed explanation here:

It appears to be missing a license file. There is a limit for elements that can be used in recognition\generation without license (demo mode).

I can advise receiving a temporary license, which will provide a full features, but only for 30 days:

If you find that product meet your demands there is a perpetual licensing available:

Hello, @Obul5750

OMR Library support photo quality of scans. Unfortunately, There is no sample code for web camera usage. I can advise searching implementation to receive images from a web camera and insert photo images into OMR library.
