初略介绍k-means，初学者可通过此文档认识什么是k-means算法(Slightly introduced at the beginning of k- means, beginners can pass this document to know what is k- means algorithm)

for water mark tec. to know about it

一个角度变换程序，在处理图像时，能够对图像中某一目标进行角度变换(A point of transformation process, in dealing with image, able to image targets in terms of a transformation)

说明：  matlab的差分算法实现以及粒子群优化算法介绍(matlab differential algorithm and particle swarm optimization algorithm introduced)

二值图像的膨胀与腐蚀函数matlab源代码(binary image dilate and erode)

哑铃状目标SAR回波仿真与成像程序，成像使用了距离多普勒算法，回波仿真中考虑了目标的后向散射随着频率的变化(the dumbbell-shaped target SAR echo simulation and imaging processing, the use of RD imaging algorithm, echo simulation takes into account the target backscatter varies with frequency)
