Hi, All!

Please, could you help me with this. I'm new to OpenCV, may be there are already existed solution. image description

I need to get coordinates of 5 points inside the circle. What is the best way to do it? I think I need to get hyerarchy of contours and find one, whitch contains 5 points with the same area. But there may be a situations, when big circle breaks by some objects behind, and we can lost closed circle... so, what you think is the best solution? And I want to notice, that this is a video, not photo processing. About 10-20 frames per second.

Thank you!
