Assigning new id to object that is passing another object. #122

I use the tracker to track people. Consider a situation where person 1 is standing and person 2 passes behind person 1 and person 2 does not have a box for several frames. In this case, the tracker assigns a new ID to person 2 after passing person 1. Why does this problem exist? And is there a solution to fix this problem?

Same problem here, I understand that this mostly happens with motion based trackers when detections are lost but then why doesn't re-id help here?

isn't re-id embedding not part of OC-SORT?
