The example apps show the total counts of each class for each frame but not the accumulated total counts (exclude duplicated appearances). I want to keep track how many unique objects of a class appear in total so I think I need to use the tracker id to discard duplicated occurrences. In other words, when an object of class A appears in multiple frames, only its first occurrence contribute to the total count of class A.
I read from the nvdsmeta.h file that
UNTRACKED_OBJECT_ID indicates that the object has not been tracked, I wonder if I can use it to detect first occurrence of an object? Say:
if(object_id == UNTRACKED_OBJECT_ID) // first occurrence update count else // subsequent occurrence, object_id is set to a value other than UNTRACKED_OBJECT_ID pass
