Abstract

Aim at improving the robustness by employing single feature tracking algorithm in visual object tracking realm, we put forward an object tracking algorithm based on the thought of game theory via multi-feature fusion. Under the framework of Mean Shift visual tracking, treating the color features and motion features expressed by optical flow as two gamers, by searching the Nash Equilibrium of their game, makes various feature's contribution reach the optimum balance, then the advantages of feature fusion are reflected better. According to experimental results, this algorithm is robust to the drastic motion of object, obstacle occlusion and background interference. This study proposes a new algorithm, which base on traditional Mean Shift algorithm and use multi-feature fusion with game theory. The algorithm shows a good tracking performance.
