Fuzzy Particle Filter Used for Tracking of Leukocytes

The particle filter is widely used in many non-linear systems. Target tracking is an important applying area for particle filter. The paper first introduced particle filter. In order to improve the tracking efficiency and tracking accuracy , fuzzy logic operation is introduced to calculate the number of the particle filter. So the particle numbers are changed dynamically according to the fuzzy logic operation result. This method was used for tracking of leukocytes. The results show that the fuzzy logic particle filter is more efficiency than normal particle filter.
