Abstract
A novel multi-regions based particle filters that effectively deals with occlusion problem in people tracking has been proposed in this paper. After locating multiple key regions, the algorithm uses several nearly independent particle filters (NIPF) to track each region which will be influenced by the proximity and/or behavior of other regions. Comparing with the tracking method based on independent particle filter, the proposed algorithm is more effective in solving long-time partial or total occlusion problem. And the performance advantage the nearly independent particle filters in comparison with a joint filter is significant. This is demonstrated by the experimental results.
