This paper investigates combinatorial and probabilistic approaches to real-time video target tracking. Of special interest are real-world scenarios, in which the presence of multiple targets and complex background pose a non-trivial challenge to automated trackers. Object tracking in an exemplary surveillance video sequence is accomplished by means of selected visual tracking techniques, based on two families of methods, combinatorial data association and Particle Filters. Based on the detailed analysis of the performance of the trackers tested, the advantages, complementary failure modes and computational requirements of each method have been identified. Taking into account the results obtained, the hybrid strategy for improved tracking performance is suggested, bringing together the best complementary features of the different tracking methods.
