视频背景非参数估计论文及matlab实现.matlab代码只实现了灰度图的背景估计，论文利介绍的彩色视频处理方法可以自己看看怎么做。(Background and Foreground Modeling Using Nonparametric Kernel Density Estimation for Visual Surveillance AHMED ELGAMMAL, RAMANI DURAISWAMI, MEMBER, IEEE, DAVID HARWOOD, AND LARRY S. DAVIS, FELLOW, IEEE Invited Paper )

susan算法，基于MATLAB的椭圆拟合(susan algorithm, MATLAB-based fitting of the elliptical)

说明：  自己编写的自适应notch fileter算法，该算法原理见清华现代信号处理(I have written adaptive notch fileter algorithm see Tsinghua principle of modern signal processing)

老外编的标准pso算法的matlab工具箱，该工具箱将PSO算法的核心部分封装起来，提供给用户的为算法的可调参数，用户只需要定义好自己需要优化的函数(计算最小值或者最大值)，并设置好函数自变量的取值范围、每步迭代允许的最大变化量(称为最大速度，Max_V)等，即可自行优化。(Part of the standard of foreigners pso algorithm matlab toolbox, the toolbox will be the core of the PSO algorithm package together to provide to the user adjustable parameters for the algorithm, users only need to define their own needs better optimization function (calculation of minimum or maximum value), and set a good function, since the range of variables, each iteration step the maximum allowable variation (known as the maximum speed, Max_V) and so on, can be self-optimizing.)
