HSV模板的人脸肤色分割程序，用于人脸识别及定位工作中(HSV template, skin color segmentation procedures for the recognition and positioning work)

随机数演示程序，可以产生均匀分布，正态分布和瑞利分布的随机数，并画图表示。(Random Number demo program can generate uniformly distributed random lognormal distribution and rayleigh, and drawing representation.)

Codes related in signal processing course and written in MATLAB. there are pdf files that explain the idea about codes. so there are more than 5 source codes.

构造模拟信号进行ICA独立分量盲源分离程序，值得参考和下载哦，可直接运行(Constructed analog signal the ICA independent component blind source separation program, worth considering and download Oh, and can be run directly)

用matlab 实现离散时间傅里叶变换的例程，方便初接触者使用。这是我dsp课的大作业(Using matlab discrete-time Fourier transform routines to facilitate early contact to use. This is my big job dsp lesson)

云模型:基于MATLAB实现的云模型计算隶属度 ”云”或者’云滴‘是云模型的基本单元，所谓云是指在其论域上的一个分布，可以用联合概率的形式（x， u）来表示云模型用三个数据来表示其特征(Cloud model: membership degree of cloud model based on MATLAB implementation "Cloud" or "cloud" is the basic unit of cloud model, the so-called cloud refers to the distribution on a domain, can use the joint probability of the form (x, U) to represent the cloud model with three data to show its characteristics)
