Particle Filter Object Tracking Visual object tracking is a difficult problem, but in recent years, particle filter-based object trackers have proven to be very effective. Conceptually, a particle filter-based tracker maintains a probability distribution over the state (location, scale, etc.) of the...
Object tracking is considered to be a key and important task in intelligent video surveillance system. Numerous algorithms were developed for the purpose of tracking, e.g. Kalman Filter, particle-filter, and Meanshift. However, utilizing only one of these algorithms is considered inefficient because...
The chaotic particle filter tracker was introduced for visual object tracking. A chaotic system was used to exploit the nonlinearities as global motion estimation. The proposed method obtains a local region based on global motion estimation for the particle filter method. In this algorithm, the dynam...
