英文摘要：

Particle filter algorithm has been proven to be a powerful tool in solving visual tracking problems. However,the problem of sample impoverishment which is brought by the procedure of resampling is a main handicap of the particle filter. In this work,an im- proved particle filter based on artificial bee colony algorithm is proposed to solve this problem. Tile particles in the particle filter are optimized based on ABC algnrithm before resampling. Thus,the particles can approximate the true state of the target better,and the number of efficient particles can be increased significantly. Experimental results demonstrate that the proposed ＇algorithm can track tar- gets robustly in various challenging conditions which outperforms the standard particle filter.
