Simulations results indicate that the auxiliary particle filters we develop have accuracy and computational complexity similar to that of the underlying particle flow filters. 展开 关键词: Gaussian processes differential equations importance sampling nonlinear filters particle filtering (numerical methods ...
In this paper, we propose a novel implementation of the PHD filter named the Gaussian particle flow PHD filter (GPF-PHD). It employs a bank of particle flow filters to approximate the PHD; these play the same role as the Gaussian components in the GM-PHD filter but are better suited to...

A filtering method called the Gaussian particle filter (GPF) based on the particle filtering concept is presented for 3D pose and motion estimation of a moving target from monocular image sequences. The method has been implemented with simulated data, and simulation results are provided along with...
First of all we apply Gaussian Mixture Model to represent the large scale WiFi database to decrease the WiFi data by no less than 95%. Secondly, we apply Particle Filter to adjust the possible calculation quantity needed for the location estimation technique. As experimental result, we achieved...
For kernel density estimation (KDE) on the data points in SMSS-D space, a Gaussian kernel was used with a bandwidth (\({\rm{bw}}\)) corresponding to Scott’s rule (\({\rm{bw}}=\,{n}^{-1/(d+4)}\)58, where n is the number of data points and d is the number of ...
Second, we consider the task of filtering the image with a Gaussian blur kernel. We exploit the separability of the kernel and perform three consecutive filtering steps using 1D filters in each direction. On the APR, this requires locally evaluating the function reconstruction. The benchmark result...
A large amount of computation of particle filter limits its engineering application. According to this problem, Quasi-Monte Carlo (QMC) sampling is used to replace Monte Carlo (MC) sampling, reducing the required computation. Quasi-Monte-Carlo Gaussian P
