matlab 在led二次光学设计中的数值计算例程，不是原创，不过很有参考价值！(matlab numerical calculation routines, led the second optical design is not original, but a good reference value.)

　　在目前的人脸图像信息处理领域中，包含有人脸识别、人脸跟踪、姿态估计、表情识别等多个研究方向，然而，所有这些研究方向都涉及到一个人脸标识和定位的问题，即必须知道人脸在图像中的位置以及尺寸——人脸检测。因此，对于一个完整的、自动的人脸信息分析系统来说，人脸检测算法是必不可少的。本文主要是对基于matlab平台的彩色图像皮肤区域分割算法及人脸检测系统的设计做了介绍。(In the face image information processing, including face recognition, face tracking, pose estimation, expression recognition research direction, however, all of these studies are related to the direction of a person the face identify and locate the problem, that is,You must know the position of the face in the image and size- face detection. Therefore, for a complete automatic face information analysis system, the face detection algorithm is essential. This paper introduced the design of the matlab platform based on the area of ​ ​ skin of color image segmentation algorithm and face detection system.)

分数阶傅里叶变换程序代码，有用可行，亲自测试过，能够放心使用····(Fractional Fourier transform program code, a useful and feasible, personally tested, can be assured use)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)
