Abstract:

Particle filter algorithm is currently used in intelligent monitoring system. It has unique advantages in non-linear， non-Gaussian filtering. However，with demands increasing to track target in the monitoring system，the algorithms continually are updated，ordinary particle filter monitoring system is no longer able to meet the growing demand. For more complex scenes，for example，an area of the background mutation movement can’t be primely monitored. Aim at this probelm，the paper used HMM particle filter to track，and realized the target of intelligent monitoring.

Key words: particle filter, HMM, mutation movement, intelligent monitoring
