Abstract: The degeneracy problem and the huge computational cost limit the usage of the traditional particle filter tracking algorithm, especially in video surveillance occasions which required higher real-time processing. The mean-shift algorithm is introduced to make particles herd to the nearby local maximum position, and the integral histogram can speed up the computing of the histogram of each particle. The speeds and effects of the traditional particle tracking algorithm are improved, and can meet the needs of real-time tracking. Experimental results prove the effectiveness of the improved algorithm.

Key words: particle filter tracking, mean-shift, integral histogram
