Practice on the system using the proposed switching method When the particle filter lost the tracking because object moving too fast,it will switch to PSO to do a global search. When the PSO to tracking the object, it will switch to the particle filter to do fast tracking. Considering both the execution speed and design flexibility, we use a NIOS II processor to calculate weight for each particle and a hardware accelerator to update particles. As a result, execution efficiency of the proposed hardware/software co-design method of particle filter and Particle Swarm Optimization is significantly improved while maintaining design flexibility for various applications. To demonstrate the performance of the proposed approach, a real-time object tracking system is established and presented in this paper. Experimental results have demonstrated the proposed method have satisfactory results in real-time tracking of objects in video sequences.
