Particle Filter with Hybrid Proposal Distribution for Nonlinear State Estimation

Abstract: Particle filters have been widely used in solving nonlinear filtering problems. Proposal Distribution design is a key issue for these methods and has vital effect on simulation results.  Various proposal distributions have been proposed to improve the performance of particle filters, but practical situations have promoted the researchers to design better candidate for proposal distributions in order to gain better performance. This paper proposes a hybrid proposal distribution designed for particle fi… Show more

“…Below, there are presented Doubled Modified Hybrid Kalman Filter (dHKFmod) and Doubled Modified Hybrid Kalman Particle Filter (dHKPFmod) algorithms. They are based on HKFmod and HKPFmod from [1], where for double methods based on traditional HKF and HKPF [2], the order of EKF and UKF algorithms inside were reversed. k|k) , P EKF1 (k|k) , y (k) ]…”

“…But it cannot be used efficiently in situations when occlusions and cluttered environments happen, due to the fact that we cannot evaluate the probability density function (PDF) before the particles are drawn. Many works (as [23], [24] and [25]) have focused their efforts on suboptimal approaches, because the transition prior based particle filter (generic particle filter) is easy to implement and has been widely used to solve problems in real-world scenarios, especially in visual tracking. Several versions of the generic particle filter, from the Condensation algorithm to the Unscented transformation, failed in complex tracking scenarios due to the sample impoverishment problems.…”
