Circle.jpg

Hi, I detect my circle like the picture in attachment. I want to track the center of my circle (I already succed to track the center and add the marker) but I want that my trackingbox is the circle like in this link https://fr.mathworks.com/help/vision/examples/motion-based-multiple-object-tracking.html where trackingbox is a rectangle around the people. I want to do this because I would like to differtiate the 2 circles when they are stacked.

Thanks for your help

So just use viscircles() to plot the circle over the image and rectangle() to plot the box.

I already use this to define my circle but now I would like to define the box of the track by this circle.I don't know if it's possible to do that. I mean define the circle as the "environment" of the cercle. Because in my case I juste define the center of my circle as the tracking point but when I stack the 2 markers the tracking Bug because they have the same "color"...
