基于集对分析的遥感图像K-均值聚类算法
SPA-based K-means Clustering Algorithm for Remote Sensing Image
摘要
Abstract
K - means clustering algorithm is a kind of hard classification based on the Euclidean distance, with each data point assigned to a single cluster. Due to the uncertainty and mixed pixels in remote sensing image,it is difficult for the traditional K - means clustering algorithm to obtain satisfactory classification results. To overcome this drawback, the authors applied the SPA ( set pair analysis) theory to the clustering algorithm of remote sensing image. The IDC ( identical discrepancy contrary ) connection degree model, which can descript unitarily the identity, discrepancy and opposition,was employed to improve K -means clustering algorithm. The improved algorithm has overcome the limitation of K - means clustering algorithm to certain extent. Clustering analysis experiments of Landsat TM image show that the improved K - means clustering algorithm is superior to K - means in classification accuracy of ground cover class components of mixed pixels.关键词
