the fuzzy membership is defined by not only the relation between a sample and its cluster center, but also those among samples, which is described by the fuzzy connectedness among samples.
在确定样本的隶属度时,不仅考虑了样本与类中心之间的关系,还考虑了类中各个样本之间的关系,并采用模糊连接度来度量类中各个样本之间的关系。
in this paper, the new method of road semi-automatic extraction based on relative fuzzy connectedness combined with road feature is proposed.
论文提出一种将相对模糊连接度和道路特征相结合进行卫星图像主干道路半自动提取的新方法。
secondly the method combines with the road characteristic and uses fuzzy connectedness to join the break road segment, and at last farther process to form the whole road network.
接着结合道路局部特征运用模糊连接度连接断裂路段,最后根据道路走向进一步完善整个道路轮廓。
the method computes fuzzy connectedness from each pixel to the seeds, and then divide…
实验表明,该算法能準确有效地分割出感兴趣区域。
