人脸识别中的matlab算法，人脸前期处理，希望对大家有用(of Matlab face recognition algorithm, face pre-processing, it may be useful to hope)

说明：  用于数据集的过采样处理，其中含有一个实例，可以参考。(Oversampling Processing for Data Sets,and it have a sample for study.)

Implementation of the general difference equation. Solution of a differential equation. Generation of discrete time exponential sequence.

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

“图像处理的偏微分方法”一书的matlab源码 (matlab sourcecode for the book"PDE method in digital image processing")

三麦克风阵列，近场定位程序，采用TDOA方法，其中延时计算采用GCC方法(three mic array，nearfield location，adopt TDOA algorithm and use GCC to calculate Time Delay)

这些MATLAB函数分别为数字图像处理Matlab版，由冈萨雷斯著作的，补充和扩展MATLAB的图像处理功能和图像处理工具箱提供MathWorks。(These MATLAB functions were created for the book Digital Image Processing Using MATLAB (DIPUM), by R.C. Gonzalez, R.E. Woods, and S.L. Eddins, Prentice Hall, 2004, ISBN 0130085197. The functions supplement and extend the image processing functionality of MATLAB and the Image Processing Toolbox, both offered by The MathWorks.)

MATLAB 的iir filter，适合巴特沃斯切比雪夫等滤波器，低通高通和带通接可以使用(iir filter MATLAB)

这个文件包含很多MATLAB用于遥感处理的代码！(This file contains a lot of MATLAB code for the remote sensing processing!)

一种基于区域增长的图像分割方法，代码实现比较简单。(An image segmentation method based on regional growth, the code is relatively simple.)
