Tracking by Sampling Trackers



We propose a novel tracking framework called visual tracker sampler that tracks a target robustly by searching for the appropriate trackers in each frame. Since the real- world tracking environment varies severely over time, the trackers should be adapted or newly constructed depending on the current situation. To do this, our method obtains sev- eral samples of not only the states of the target but also the trackers themselves during the sampling process. The track- ers are efficiently sampled using the Markov Chain Monte Carlo method from the predefined tracker space by propos- ing new appearance models, motion models, state repre- sentation types, and observation types, which are the basic important components of visual trackers. Then, the sam- pled trackers run in parallel and interact with each other while covering various target variations efficiently. The ex- periment demonstrates that our method tracks targets accu- rately and robustly in the real-world tracking environments and outperforms the state-of-the-art tracking methods.
