Particle filter (PF) has proven successfully for nonlinear and non-Gaussian estimate problems, but its degeneracy will influence the results of tracking. Therefore in the paper, the optical flow algorithm is utilized to generate the proposal distribution of particle filter. With the velocity message which is estimated by optical flow algorithm, the particles could be generated in a right direction...
Detecting and tracking up to 8-9 targets is already an arduous task for traditional methods. So it is even more challenging to deal with crowd objects. In this paper, segmentation and density analysis for video crowd flow is realized by a chaotic dynamics based approach. Crowd motion system is treated as a chaotic dynamic system, and crowd targets are treated as particles. As a result, Finite Time...
As the development of the rural and urban economy, the number of the motor vehicles has been skyrocketing. In the condition of increasingly enhancing locomotive speed nowadays, railway crossing security is becoming a bottleneck to restrict the railway transportation ability. This study introduces the basic modules which constitute the railway crossing surveillance and warning system, formulates the...
