中文说明： isodata 迭代自组织的数据分析，Matlab实现界面友好，基于欧几里得距离的聚类分析，添加噪声处理，结合PCA的尺度不变特征变换(SIFT)算法，从先验概率中采样，计算权重。
English Description：
ISODATA iterative self organizing data analysis and Matlab interface is friendly and Euclidean distance based clustering analysis, add noise to deal with PCA scale invariant feature transform (SIFT), sampled from the prior probability to calculate the weight.
