人脸图像的2级小波分解，用MATLAB实现。可得到人脸图像的二级小波分解图。使用时只需把图片名称改成自己所具有的即可(Face feature extraction)

这个是关于AM调制的MATLAB仿真程序，对初学MATLAB调制的来说很有用，其中含有仿真图。(This is the AM modulation MATLAB simulation program, very useful for the beginner MATLAB modulation, which contains the simulation Fig.)

介绍数字滤波器的定义、分类及实现方法。讨论IIR滤波器、FIR滤波器的设计方法以及如何运用MATLAB中的DSP Blockset工具箱设计数字滤波器。(Introduce digital filter definition, classification and realization. Discussion of IIR filter, FIR Filter design and how to use the DSP Blockset MATLAB toolbox to design digital filters.)

说明：  利用平面波展开发计算二维光子晶体的能带结构(Show the development of the use of plane-wave calculation of two-dimensional photonic crystal band structure)

In this document we proposed a face recognition algorithm that enhance the recognition rate and reduce the complexity.

algoritmo pavilis, para el adelgazamiento de imagenes

利用matlab仿真双边带信号（DSB）的调制与解调，适用于初学者(Band signal using matlab simulation bilateral (DSB) modulation and demodulation, for beginners)

matlab codes for spatial domain filtering

cost存放了一个强连通图的边权矩阵，作为一个实例。 可在workspace中加载 运用此算法要注意多次试验。(storage cost of a strongly connected graph edge weight matrix, as an example. Loaded in the workspace using this algorithm is to pay attention to several tests.)

这是2005年Dollar发表的文章中，人体行为识别的全部代码。希望有用、(This is a 2005 article published in the Dollar, human behavior recognition of all the code. I hope useful,)
