经典的hough直线变换检测算法，可以极坐标进行转换，然后再检测直线(Line detection algorithm)

this is heart rate detection method

说明：  混沌工具function [dlogCr,dlogr,dlogCrCI]=vr(logCr,logr,alpha)(function [dlogCr,dlogr,dlogCrCI]=vr(logCr,logr,alpha))

该压缩包的程序实现对图像的边缘进行检测，并且对图像进行阈值分割。源码全部为自己编写，效果不错。不知道上传matlab的源码能不能开通会员，所有上传的都是自己的代码，虽然有些简单但是都是自己的劳动，刚起步，希望和大家交流。(of the compressed image program to the brink for testing and the right image thresholding segmentation. Source for all the preparation work to be done. Upload Matlab do not know the source can open membership, are all uploaded the code, Although some are simple but their work has just started, and we hope that the exchanges.)

基于快速傅里叶变换的MATLAB实现，内附有源程序(MATLAB based on fast Fourier transform implementation, enclosing a source)

用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图，FFT实践及频谱分析(Matlab generated by sine wave, square wave, and the white noise signal, and display their time-domain waveform, FFT spectrum analysis of practice and)

用于生成低通滤波器传递函数，有调用函数，两个一起才可以用。(Used to generate low-pass filter transfer function. Have to call a function with only two can be used.)

This document contains a tutorial on Matlab with a principal components analysis for a set of face images as the theme
