Particle filters (PF) have been widely used in the estimation of the state transition and observation of non-linear/non-Gaussian systems, and samples degeneracy is the main issue of particle filters. In this paper, a novel PF - selectively iterative particle filter (SIPF) is proposed for target tracking in wireless sensor networks (WSNs). There are two novel strategies in SIPF, the statistics based...
Camera global motion estimation is critical to the success of video stabilization. This paper presents an effective and robust feature based motion estimation method. In the proposed approach, feature points are collected from input video sequences based on Speeded Up Robust Features (SURF). Random Samples Consensus (RANSAC) is used to remove local motion vectors and incorrect correspondences. In...
A new filtering algorithm - PSO-PF was proposed for nonlinear dynamic systems. Basing on the concept of re-sampling, particles with bigger weights should be re-sampled more time, and in the PSO-PF, after calculating the weight of particles, some particles will join in the refining process, which means that these particles will move to the region with higher weights. This process can be regarded as...
