ImageFrequencyFiltering

稀疏表示，可以用于分析信号处理的算法程序(sparse representation)

人脸识别中的光照处理方法，使用混沌与分形分析的例程，实现了图像的灰度化并进一步用于视频监视控。( Face Recognition light treatment method, Use Chaos and fractal analysis routines, Achieve a grayscale image and further control for video surveillance.)

混沌现象出现于非线性系统中。Matlab模拟了复摆运动行为及混沌现象(Chaotic phenomena in nonlinear systems. Matlab simulation of the compound pendulum movement behavior and chaos phenomena)

计算mie散射过程中的散射幅度函数，对研究粒子散射问题有较大帮助(Mie scattering process of calculating the scattering amplitude function, the study of particle scattering problems have more to help)

移动通信系统中正交频分复用OFDM的matlab仿真，包括调制和解调等(Mobile communication system in orthogonal frequency division multiplexing OFDM matlab simulation, including the modulation and demodulation, etc)

数字滤波器是一种用来过滤时间离散信号的数字系统，通过对抽样数据进行数学处理来达到频域滤波的目的。(FIR Digital Filter Design)

Discrete cosine transform

是一个小波神经网络的程序，非常好用，有需要的自行下载(A wavelet neural network program, very easy to use, there is a need to download)

本程序实现了DFE下的rake接收机，程序简单易懂，极具逻辑性，相信很适合通信专业的人士学习(This program realises the DFE rake receiver,which is very clear and easy to understand. Definitely, this is appropriate for anyone who majored in telecommunication)

主要包括图像的中值、均值去噪、非局部均值、分块局部去噪算法；还有均方误差和峰值信噪比评价、以及matlab基础学习资料如边缘检测、小波变化、灰度值转换等(Including image median, mean denoising, non-local means, block local denoising algorithm also mean square error and peak signal to noise ratio evaluation, and matlab based learning materials such as edge detection, wavelet transform, gray scale value conversion wait)
