Read Images from a scanned PDF Document

Hi all,

im new in UI Patch and had a question regarding Images in scanned PDF (ex. a checked checkbox).

My Goal is to check wheather or not a Checkbox in a scanned PDF ist empty or not. Attached you will find the checkboxes im talking about.

Do you guys have any ideas or examples how i could do that?

Thanks in advance!
