Hi Guys,
I am building my first app with opencv ever and try to recognize openings of defined size, arranged in known patterns on a white foil/paper. If some openings are missing I need to recognize it and need the location feedback. Openings will be black, so contrast should be of no issue.
My question: what opencv algorithm would be the best to achieve this.
Explanatory note: Since the opencv tool box is huge their might be a lot of tools that would do the job in general, but neither I want to shoot on birds with canons nor use a dull knife to cut precisely. I already tried similarity measurement as described in the official documentation, it somehow works but doesn't seem to really fit in that situation.
Thanks so much for your help and ideas!
