Abstract

General ob ject tracking is a challenging problem, where each tracking algorithm performs well on different sequences. This is because each of them has different strengths and weaknesses. We show that this fact can be utilized to create a fusion approach that clearly outperforms the best tracking algorithms in tracking performance. Thanks to dy- namic programming based tra jectory optimization we cannot only out- perform tracking algorithms in accuracy but also in other important aspects like tra jectory continuity and smoothness. Our fusion approach is very generic as it only requires frame-based tracking results in form of the ob ject’s bounding box as input and thus can work with arbitrary tracking algorithms. It is also suited for live tracking. We evaluated our approach using 29 different algorithms on 51 sequences and show the su- periority of our approach compared to state-of-the-art tracking methods.
