有k_means和em算法,k_means算法用来减少结点数目(There k_means and em algorithms, Reduce the number of data points using the k-means algorithm )

emd算法程序，希望对大家有所帮助(emd algorithm procedures, we hope to help )

实现车牌识别并自动定位* 主函数：MyCarLocal.m * * im2gray 将图像转化为灰度图象； * * mycombine 区域合并； * * select 前期处理的区域选取； * * isplate 判断检测出的区域是否为车牌区域，还需要继续完善。(Automatic license plate recognition and positioning to achieve)
