In this dissertation, K-means algorithm is modified, employing spatial context information. The modified algorithm keeps the strongpoints that K-means has, and it depends not only on spectral information but also spatial information.
影像分类是将栅格影像转换为矢量数据的一种重要途径;本文对K均值算法进行改进,将空间上下文引入其中;在保持其非监督、易于实现等优点的前提下,弥补其单纯依赖光谱信息的不足。
