求矩阵腐蚀，膨胀的算法，以及梯度、平滑和高帽变换运算。(Matrix erosion, dilation of the algorithm, and the gradient, smoothing and hat transformation operations.)

对图形图像进行处理，使图形图像配准，更为准确(The graphic image processing, the graphics image registration, more accurate)

说明：  元胞自动机的例子，细胞生长法完成初始化，然后计算晶粒的生长，入门级别程序(Examples of cellular automata, cell growth method to initialize, and then calculate the grain growth, entry-level program)

AP聚类方法，是08年发表在“科学”上的聚类方法，本人从图像图像方面研究近十年，这是我所见过最好的聚类算法，本程序提供聚类演示，还把它用图像分割试验（matlab7.0环境调试）。(AP clustering method, is 08 published in " Science" on the clustering method, the image from the image in my research in recent years, this is the best I have ever seen clustering algorithm, Clustering presentation of this program provides, but also test it with the image segmentation (matlab7.0 debugging environment).)

SPIHT的MATLAB源代码,希望对有需要的朋友有所帮助.(SPIHT the MATLAB source code, in the hope that there is a need to help a friend.)

文章对几种常用的基于循环前缀(CP)的最大似然同步算法进行了分析，并对其频偏估计方差进行了比较；同 时针对基于CP 的同步算法在多径衰落信道下性能较差的情况，提出了一种改进的CP 同步算法并进行了仿真，结果表明相比 于原ML 算法，文中算法在多径信道下可有效提高频偏估计性能。(】This paper does some research on multiple maximum-likelihood (ML) algorithms based on cyclic prefix (CP) and compares variances of frequency-offset estimation After the analysis of the bad performance of CP based algorithms in multi-path fading channels, an improved CP algorithm is proposed and the simulation shows that this algorithm can improve its performance effectively in multi-path fading channels.)

说明：  遗传算法几个好的工具箱，给大家分享，希望互相交流(Several good genetic algorithm toolbox, to share with you the hope that mutual exchanges)
