小波变换去噪，matlab源代码，可以去除高频噪声(Wavelet denoising, matlab source code, can remove high frequency noise)

Hand Gesture Recognition NOTES: 1) For the details of the algorithm investigate the following images: -AlgorithmOverall.jpg -MKRoDAlgorithm.jpg 2) The prototype is implemented on MATLAB 7.0 and revised in MATLAB 7.10.0 3) The backgrounds of input images have to be purely ‘black’ and the details of the content(palms, fingers) must be clear for accurate recognition of the ASL. 4) A reduced ASL dataset is used. The dataset contains the following ASL gestures: "b,c,h,i,o,l,y". ---------------------------------------------------------------- Use execHGR.m inside the Project folder in order to execute the program. I hope you will enjoy it.

用MATLAB进行Sigma 采样，用于数值计算或者数值滤波(Sigma sampling conducted with MATLAB for numerical calculations or numerical filtering)

说明：  仿射变换和猫脸变换是图像加密算法中最基本的算法之一，很多重要的加密算法都是在此基础发展而成的，该程序供研究加密算法的初学者参考使用。(Affine transformation and cats face is the most basic image encryption algorithm in one of many important cryptographic algorithms are evolved on this basis, the program for research reference for beginners to use encryption algorithms.)

：SPWM调制技术是通过改变输出方波的占空比来改变等效的输出电压，其调制波为正弦波，脉冲宽度间占空 比按正弦规率排列， 这样输出波形经过适当的滤波可以做到正弦波输出。它广泛的用于支流交流逆变器。本次实 验使用Matlab/Simulink对SPWM技术进行仿真并分析数据。(: SPWM modulation by changing the duty cycle square wave output to change the equivalent output voltage, the modulated sine wave, pulse width, duty cycle between the rate at sine arranged so that the filter output waveform can be done properly to the sine wave output. It is widely used in branch AC inverter. The experiment uses Matlab/Simulink simulation of the SPWM technique and analyze data.)

基于matlab中M文件应用，主要实现数值分析课程的应用(Matlab-based M documents, the main numerical analysis courses Application)

说明：  主要用于故障诊断的神经网络预测KPCAcontourmap代码文件(Neural Network Prediction KPCAcontourmap Code File for Fault Diagnosis)
