any chance you're talking about opencv's tracking module?

I'm not sure what you mean. I'm using the built-in tracker csrt. When testing it I noticed it sometimes loses tracking/tracked object goes off-screen. I want to combine this with YOLO object detection to create new tracking ROI (boxes around the objects) every few seconds to update the previous ones. When I do that however they start adding up, because the old ones don't disappear. Therefore my question is if there's a way to make the current tracked objects disappear. Thanks

the old ones don't disappear.

indeed. there is a clear() function, but it is not implemented consistently for all trackers.

all you can do is -- delete the old tracker, and create a new one.
