This function is another tutorial on how to do computer vision type stuff with Octave/Matlab. It shows how to implement Hartley and Zisserman s "DLT" algorithm for estimating a homography from point correspondences

说明：  用matlab编写的fft快速傅立叶变换及逆变换函数,其中flip1是供ditfft函数调用的倒叙子函数。(using Matlab fft prepared by the fast Fourier transform and inverse transform function, which is flip1 ditfft function call for the Warrior unreachable.)

GMVQ算法，stanford大学Gray先生经典之作(GMVQ algorithm, stanford University of Mr. Gray for the classic)

clear 从内存中清除变量和函数 exit 关闭MATLAB load 从磁盘中调入数据变量 pack 合并工作内存中的碎块 quit 退出MATLAB save 把内存变量存入磁盘 who 列出工作内存中的变量名 whos 列出工作内存中的变量细节 workspace 工作内存浏览器 (There is one outlier in the data of , but is not of data .For and the line of Q2 is in the middle of the box, so there are not asymmetries for both and .)

经济类的实用的时间序列分析软件包，已经是目前最好的版本了。USCD_GARCH，可以研究非平稳时间序列数据。(kind of practical time series analysis software package, is the best current version. USCD_GARCH can study non-stationary time series data.)

em算法的代码，以及K-means算法代码(em algorithm code, and the K-means algorithm code)

matlab方面讲的比较清楚，大家都来下下，很不错的哦。原理与工程应用(book about matlab)

产生不同频率、幅度的正弦波信号，叠加后，设计低通、带通滤波器进行正弦信号的谱分析及提取。(The sine wave signals with different frequencies and amplitudes are generated. After superposition, the low-pass and bandpass filters are designed for spectrum analysis and extraction of sinusoidal signals.)

egion growing approach is the opposite of the split and merge approach: An initial set of small areas are iteratively merged according to similarity constraints. Start by choosing an arbitrary seed pixel and compare it with neighbouring pixels. Region is grown from the seed pixel by adding in neighbouring pixels that are similar, increasing the size of the region. When the growth of one region stops we simply choose another seed pixel which does not yet belong to any region and start again.

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)
