图像索材，学习图像处理必须的一些常用图片，愿大家能轻轻松松学习图像！(Image cord material, learn to be a number of image processing used pictures, would like to learn that we can easily image!)

3 phase induction motor

Digital ImageProcessing Using MATLAB 数字图像处理（MATLAB版） 冈萨雷斯和伍兹所著 这本书的matlab代码编译后的文件 可以在matlab中使用 (Digital ImageProcessing Using MATLAB digital image processing (MATLAB version) written by Gonzales and Woods book compiled matlab code files can be used in matlab)

说明：  在matlab环境下生成一个正方形中心嵌套一个圆，并利用curvelet变换显示出其各个子层的系数图，良好的体现了curvelet变换的各向异性的性质。(In the matlab environment to generate a nested square center of a circle, and the use of curvelet transform shows that its coefficient of sublayer maps, a good reflection of the curvelet transform the nature of the anisotropy.)

关于排队模型的资料整理，很全面，应用到很多方面，欢迎下载~~~(A lot of materials about queue model, very useful, and they are many applications, welcome to download. )

The ouput is the TE/TM band structure (first five bands) along pricipal directions (G-X-M-G) of a square-lattice photonic crystal with unit cell consisting of a substrate of "epb" relative permittivity with circular rods(holes) of "epa" relative permittivity and radius "r". Usage is SharifPWE_BZplot(N,RES,r,epa,epb) N: N in PWE algorithm (number at which the summations are truncated) RES: number of the divisions on every side of BZ#1 r: normalized radius of the circle of holes/rods (0<r<0.5) epa: relative permittivity of holes/rods epb: relative permittivity of the substrate Written by Amir Hosseini for the Course Photonic Crystals (C) Copyright 2005 School of Electrical Engineering Sharif University of Technology All Rights Reserved

说明：  EMD分解信号，利用相关系数选取有效本证模态函数，最终得到滤波信号(EMD decomposes the signal, uses the correlation coefficient to select the effective intrinsic mode function, and finally obtains the filtered signal.)

你见过 MATLAB 最早的版本吗？下载一份 MATLAB 1.0,(只有182K, 只有20来个函数) 体会一下吧。MATLAB早期表示矩阵是用 <> 而不是 []。 (Have you seen the first version of MATLAB you? Download a MATLAB 1.0, (only 182K, only 20 to a function) experience yourself. MATLAB is a matrix of early that < > instead of [].)

通过matlab代码，小波包分析提取振动信号中的特征频率，可以得到很精确的幅值、频率、相位估计。( By matlab code, Wavelet packet analysis to extract vibration signal characteristic frequency, You can get a very accurate amplitude, frequency, phase estimation.)
