Can you give us a little more information about what you want to track? Are only the topmost balls ok to track? Or are you hoping to identify all the balls in the image? I.e. even ones behind others?

STeven.

Can you track these balls?

I'm new to Roborealm, and I'm learning all the modules and how to apply each module in each situation.

If you can track the tennis balls in the image below, post a screenshot, and tell me what modules they used and how/why you used them, that would be amazingly great.

Thanks.
