hi, my idea here is to draw a region of interest on a marker. the marker is square in shape printed on a piece of paper. I want to draw a region of interest around the marker and crop it out so that i can process it further. i want to detect and hopefully track the marker in the image.
i hope i made my idea clear. it there is any uncertainties let me know and ill clarify.

You idea is clear enough, I guess. But do you have a question, or are you just notifying us of your project? Well, good luck with it. If you do come up with any questions, post them along with the URL of your image (where you uploaded it to) and your attempt at coding up your idea.

@messaoudi nada, like I said "Ask in a new question with your image attached if you need more help.". I clicked on your name but did not see the new question in a new thread. Did you do this yet? Let's not hijack @genesis's 8 year old thread here.

you could also use Hough Transform and your marker's dimensions to in order to find it on a larger image.
