我以前主要做MTALAB图像处理工作，现在慢慢整理以前的代码，上述未简单的图像对数变换处理程序(I used to do MTALAB main image processing work, and now slowly finishing the previous code, these are not a simple logarithmic transformation of the image processing)

对MATLAB的应用和操作进行了说明，对MATLAB入门级初学者非常有用(Application and operation of MATLAB are described, for entry-level MATLAB is very useful for beginners)

使用案例讲解了matlab中的随机数生成，有源代码程序(Generating random Numbers)

Matlab中进行二维离散傅立叶变换,并显示频谱图的方法。(two version discreate Forier Transemation baced on MATLAB)

语音信号的分帧处理，实现语音的非平稳化为准平稳过程，利用一些平稳信号的处理方法来处理语音信号。(The sub-frame of the speech signal processing, non-smooth voice of whichever stationary process, some stationary signal processing methods to process voice signals.)

维纳滤波器用于自回归过程+噪声滤波，得到均方误差与滤波器维数，均方误差与自相关的关系。(Wiener filter for the the autoregressive process+ noise filtering, mean square error filter dimension, the mean square error autocorrelation relationship.)

the code contain iris recognition code

本程序关于matlab随机信号实验中计算统计值，如平均值方差均方值等，有图形化界面(This program on matlab random signal calculation in the statistical data, such as average variance mean square value, graphical interface)

采用时域、频域、FFT小波变换及数学形态等分析方法完成对滚动轴承的故障诊断(Fault diagnosis of rolling bearing is completed by using time-domain, frequency domain, FFT wavelet transform and mathematical morphology.)

MATLAB编写的图像DOG处理程序。处理生成图像的高斯差分图(DOG written in MATLAB image processing program. Image processing for generating the Gaussian difference image)
