标题：PAIRWISE LINKAGE FOR POINT CLOUD SEGMENTATION 作者：Lu, Xiaohu and Yao, Jian and Tu ●论文摘要 ?...这篇文章中，我们首次提出一种新颖的分层聚类算法----pairwise Linkage（p-linkage），能够用来聚类任意维度的数据，然后高效的应用于3D非结构点云的分类中，P-linkage 聚类算法首先计算每个点的特征值...实验结果在2d-4d不同的维度合成数据充分证明该P-Linkage聚类的效率和鲁棒性，大量的实验结果在车载，机载和站式激光点云证明我们提出所提方法的鲁棒性。...In this paper, we first present a novel hierarchical clustering algorithm named Pairwise Linkage (P-Linkage...The P-Linkage clusteringalgorithm first calculates a feature value for each data point, for example,
ward linkage :它是用来最小化数据的差异与层次的方法（离差平方和法）。 Maximum linkage:用于最小化集群数据点的最大距离。...Average linkage:用于平均集群数据点的距离。 Single linkage:用于最小化集群中数据点的最近距离。 通过树状图可以看到分层聚类的可视化 ?...Single linkage在有噪声的数据中表现不好，ward linkage由于距离不变而不能给出合适的聚类，但在适当平衡的聚类中很好，如果我们不考虑欧氏距离，则可以使用Average linkage...当我们使用ward linkage 时，我们只能使用欧几里得距离度量。...determine the number of clusters import scipy.cluster.hierarchy as sch dendrogram = sch.dendrogram(sch.linkage

Complete Linkage：Complete Linkage的计算方法与Single Linkage相反，将两个组合数据点中距离最远的两个数据点间的距离作为这两个组合数据点的距离。...Complete Linkage的问题也与Single Linkage相反，两个不相似的组合数据点可能由于其中的极端值距离较远而无法组合在一起。...Average Linkage：Average Linkage的计算方法是计算两个组合数据点中的每个数据点与其他所有数据点的距离。将所有距离的均值作为两个组合数据点间的距离。...) / 2)) plt.subplots(nrows=nrows, ncols=ncols) for i, linkage_method in enumerate(linkage_method_list...): print('method %s:' % linkage_method) start_time = time() Z = linkage(X, method=linkage_method
