Abstract: Simultaneous tracking of multiple objects is a state-of-art problem in the field of computer vision. The problems of tracking single object and tracking multiple objects are not same. For tracking multiple objects, lots of problem can arise due to abrupt object motion, multiple object interaction, drifting of object etc. Some recent work has proposed solution to minimize those problems. The main goal of this article is analyzing the recent work in multiple objects tracking to handle those challenges. Here, Different proposed penalty functions are discussed to handle the multiple objects tracking problem. We also comprehensively discussed contribution and limitation of recent advancement in the field of multiple object tracking.

Keywords: Tracking problems, Tracklet, Hijacking problem, Drifting problem.
