particular, fuzzy clustering algorithm fuzzy C means clustering (FCM, Fuzzy C-Means) segmentation algorithm, carefully study the image segmentation algorithm based on fuzzy clustering in the number of categories to determine the initial cluster, The initial cluster centers and membership functions of ...
1.Because the spatial information is not considered in the traditional fuzzy c-means(FCM) clustering algorithm,the serious inaccuracies with synthetic aperture radar(SAR) image segmentation can be caused by using the FCM algorithm.传统模糊c-均值聚类算法没有考虑图像像素空间信息特征,在应用于合成孔径雷达...
Thefuzzy c-means(FCM) algorithm is one of the most widely used fuzzy clustering algorithms. The centroid of a cluster is calculated as the mean of all points, weighted by their degree of belonging to the cluster: In this article, we’ll describe how to compute fuzzy clustering using the ...
