Why don't you store the image path when generating that image? Or ask the user?

Otherwise, you are left roaming around the file system trying to search for that image — with no guarantee of the search result.

You didnt understood the problem. He isnt searching for files, but for some sub area in a bigger picture.

Solution 1

With your basci knowledge that task will be difficult to solve. OpenCV supports a feature named "template matching". Read the documentation and sample code of template matching to understand it.

Good luck!
