From the doc:
When the plugin is operating as a secondary classifier along with the tracker, it tries to improve performance by avoiding re-inferencing on the same objects in every frame. It does this by caching the classification output in a map with the object’s unique ID as the key. The object is inferred upon only when it is first seen in a frame (based on its object ID) or when the size (bounding box area) of the object increases by 20% or more.
Question 1: is the object “unique ID” is the ID assigned by the tracker?
Question 2: “bounding box area” change, are we talking about the bbox of the PGIE or the bbox of the tracker?
Question 3: is the purpose of having this setting “classifier-async-mode=1” to increase performance? If so how much of a different will it making if we set classifier-async-mode=0 instead?
