The State of the Art in Multiple Object Tracking Under Occlusion in Video Sequences

Abstract

In this paper, we present a review of existing techniques and systems for tracking multiple occluding objects using one or more cameras. Following a formulation of the occlusion problem, we divide these techniques into two groups: mergesplit (MS) approaches and straight-through (ST) approaches. Then, we consider tracking in ball game applications, with emphasis on soccer. Based on this assessment of the state of the art, we identify what appear to be the most promising approaches for tracking in general and for soccer in particular. 1.
