@abewley First of all thanks for this wonderful piece of work...it literally gave me insights into object tracking...just one question for you...can you please tell me for what are the “min_hits” and “hit_streak” parameters for? I tried a lot to understand but could not figure it out? Just one more request please give an elaborate description of it!!!

Thanks in advance!!!

_hitstreak is quite literally a track's hit streak. By hit, a match of a track with a new detection is implied. So for a given track, hit_streak is the total number of times it consecutively got matched with a detection in the last frames. _minhits is the minimum value of hit streak of a track, required, such that it gets displayed in the outputs.

Is this used to remove some false positive in only unconsecutive frame, but this will cause re-entering problem?If one frame is miss detected, once it has been detected again, due to the hit_streak, it wont displayer once. And actually the tracker hasn't been removed, why not just display them?
