Centralization problem of contacting interaction in multiple object tracking

In this paper we introduce a definition of centralization problem in multiple object tracking. The centralization problem occurs when more than two targets are contacting in close area. As a result, their trackers could be wrongly located in the center position of their targets. It is especially found when the appearances and shape of contacting targets are identical and the likelihood score for each tracker can be maximum value in their central position among their targets. After centralization problem their tracker could track wrong targets. Therefore we propose new interaction model to avoid centralization problem and our performance shows that almost all of centralization problem can be removed.
