Document says about ‘secondary-reinfer-interval’ - Re-inference interval for objects, in frames

Does that mean the secondary model does inference on the same object(detected by pgie) only after every ‘secondary-reinfer-interval’? How does it keep track of the object id without a tracker? Can you please explain how it works.

Thanks.

I checked the post. Can you clarify on this comment - GstNvInfer does not have property secondary-reinfer-interval - #9 by mchi
This works irrespective of tracker?

It is used to adapt the behavior of SGIE and is independent of tracker.
