Balanced PSO,可作为benchmark比较(You campare your algorithm with it.)

说明：  如何在一个方形区域画一个半径为小数的圆，也要求画出方形区域，并指出圆的位置(how to plot a circle and a square,please point the location of the circle)

这个程序是用matlab 编写的GMSK的调制程序希望对大家有用(This program is to use matlab GMSK modulation of the program for people to use)

一种基于复合混沌映射的单向Hash函数构造(One-way Hash function construction based on composite chaotic map)

直方图均衡：原始图的直方图变换为均匀分布的形式，这样就增加了象素灰度值的动态范围从而达到增强对比度的效果 中值滤波：中值滤波属于非线性平滑滤波器，它可以消除噪声又能保护图象的细节(histogram equalization : the original plan to transform the histogram in the form of uniform distribution. This will increase the value of the pixel gray areas so as to achieve dynamic contrast enhanced effect of filtering : Median filter is nonlinear smoothing filter, it can eliminate noise while preserving image details)
