说明：  基音区域&基音频率 自相关 matlab程序(Regional &amp pitch frequency Pitch autocorrelation matlab program)

MICROSOFT FOCUS COBOL VERSION 3.0 COMPLIER

LZ编码MATLAB算法,并且包含含有性能分析(the LZ coding of matlab，With performance analysis and includes)

该程序仿真了机载雷达对地面微动目标成像过程及结果。验证了微动的成对回波理论及微动对雷达成像造成的影响，改变微动参数，可看到鬼影点、灰度条带、直线圆列等由于微动参数不同而产生的不同现象。(refer to the chinese introduction)

VMD用于信号去噪，去噪效果优于EMD，是EMD算法的一种改进算法(VMD for signal denoising, denoising effect is better than EMD, EMD algorithm is an improved algorithm)

说明：  遗传寻优算法(Genetic optimization algorithm)

采用matlab编写的利用共轭梯度法求解矩阵方程(Prepared using matlab conjugate gradient method using matrix equation)

说明：  初学微分方程数值解很实用的书籍，例子很详细，并附有程序。(Good book for student who wants to study tne numerical solution of differential equations)

One of Biometrics fields is face recognition & face expression recognition ... 1- In face recognition .. we need to design authentication program by training a neural network ,there are two source codes..one of them is based on Discrete Wavelet Transform with Perceptron Neural Network.. and the other based on Discrete Cosine Transform with Perceptron Neural Network ... 2- In face expression recognition .. we defined the condition of the person (nature,happiness,disgust or anger) this source code is based on Principle component analysis(PCA) .. * we need to now about digital image processing ,neural network and PCA...
