local histogram. My friend give this to me. I hope it will be helpful to others.

PUDN XIEXIE西南交通大学赵宏宇老师的教学课件(ORIGIN OF SEJTU.)

基本粒子群算法的一些英文资料，在此基础上衍生出了许多优化粒子群算法(Particle Swarm some English information derived on this basis, a number of particle swarm optimization)

Some features and classification function

数学建模中常用的数据插值程序，经整理，有注释(Commonly used mathematical modeling data interpolation procedures, have been collated, annotated)

说明：  PROJECT ANALYSE WITH 3D MODEL AND PIE CHART MENU

在matlab平台中用fisher方法对手写的数字进行分类(Fisher method for handwritten numeral classification)

说明：  在MATLAB中可以当做发射信号的缓冲，以提高系统的稳定性，从而防止数据的剧烈变化(BUFFER Buffer a signal vector into a matrix of data frames. Y = BUFFER(X,N) partitions signal vector X into nonoverlapping data segments (frames) of length N. Each data frame occupies one column in the output matrix, resulting in a matrix with N rows.)

基于小波变换的图像增强，包含整个处理过程(Image enhancement based on wavelet transform, including the whole process)

衰落是由于发射机与接收机之间空间位置的微小变化引起的，描述小范围内接收信号场强中瞬时值的快速变化特性，是由多径传播和多普勒频移两者共同作用的结果，包括由多径效应引起的衰落和信道时变性引起的衰落，具有信号的多径时延扩展特性和信道的时变特性(Fading is caused due to a slight change of the position of the space between the transmitter and the receiver, the characteristics of the receiving signal field strength, the instantaneous value of the rapid changes in the description within, by multipath propagation and Doppler frequency shift of the joint action of botha result, time-varying fading caused by multipath effects and channel fading due to multipath delay spread characteristics and channel time-varying characteristics of the signal)
