中文说明：
ISODATA算法是在k-均值算法的基础上，增加对聚类结果的“合并”和“分裂”两个操作，并设定算法运行控制参数的一种聚类算法,从而实现遥感影像的非监督分类
English Description：
ISODATA algorithm is a clustering algorithm based on K-means algorithm, which adds two operations of "merging" and "splitting" the clustering results, and sets the control parameters of the algorithm, so as to realize the unsupervised classification of remote sensing images
