Tutorial on Gabor Filter

说明：  风机的数学模型，通过公式搭建风机的数学模型matlab程序，很实用。(The mathematical model of the fan, through the formula to build the mathematical model of the fan matlab program, is very practical.)

Design of Filters using GUI (The code provides the user friendly GUI usage in filter design)

有12个外表一模一样的小球，其中有一个的质量和其他11个球不一样（11个球的质量完全相同） 而且该球不知道是轻点还是重点。现在给你一个天平（无砝码），只有3次测量机会，请你找出该球。(12 looks exactly the same ball, which has a quality and not the same as the other 11 balls (11 balls in the quality of the identical) and that the ball does not know the point or focus light. Now to give you a balance (no weight), only 3 measurements chance, you find the ball.)

说明：  matlab遗传算法工具箱，解决遗传算法中函数不识别的现象(matlab genetic algorithm toolbox to solve the genetic algorithm function does not recognize the phenomenon of)

说明：  本程序一维数据的EM算法实现，稍作修改就可以成为多维数据的EM算法实现。(EM algorithm for one-dimensional data of the program implementation, minor modifications can become the cube of the EM algorithm.)

将数字信号转换为模拟信号的电路称为数模转换器（d/a转换器或dac）(digital to analog converter)

本程序可以产生LFM信号，经过实验验证，程序正确，可以执行，改变参数即可得到你想要的图形(produce a LFM signal)

这是外国人实现的非线性主成份分析，可下载相应的文章，可用来降维！(Applies the kernel method to unsupervised algorithms as for instance Principal Component Analysis. This gives a principled and efficient approach to nonlinear PCA)
