粒子滤波中粒子数与误差关系，plot the relation between the particle number and error-Particle filter in the relationship between particle number and error, plot the relation between the particle number and error

一种综合多种算法的车辆检测和追踪方法，运行时间较长，但效果很棒(We implement a system for vehicle detection and tracking from traffic video using Gaussian mixture models and Bayesian estimation. In particular, the system provides robust foreground segmentation of moving vehicles
