Overlapped Distribution Based Efficient Particle Filter Calculation

Abstract

Particle filter is a powerful tool for video tracking however its large amount of calculation restricts its application especially when the number of particles is large. This paper analysis the distribution of the particles, and the finite additive feature in the weighting calculation of the particles. Then this paper proposed a method which utilized the overlapped particles thus up to 81.22% time consumed is reduced in computation. Experimental results show its validity.
