说明：  此程序基于matlab环境，实现小波、PCA、像素选大选小融合并有信息熵、平均梯度等融合评价标准(This program is based on matlab environment, and wavelet, PCA, pixel selection and integration of the election have little information entropy, average gradient of integration evaluation criteria)

The method works as follows. 1. For a data set with dimensionality, d, compute the variance of data in each dimension (column). 2. Find the column with maximum variance call it cvmax and sort it in any order. 3. Divide the data points of cvmax into K subsets, where K is the desired number of clusters. 4. Find the median of each subset. 5. Use the corresponding data points (vectors) for each median to initialize the cluster centers.
