2) R*-tree

R*-tree

A Spacialtemporal Index Based on R*R*-tree;

一种基于R*-tree的时空索引

A new simplified algorithm for triangular mesh surface is proposed,which organizes the topological structure of the triangular mesh surface based on R*R*-tree spacial index structure to inquire the topological neighborhoods of the triangular mesh surface.

该算法采用R*-tree组织三角网格曲面的空间拓扑结构,实现了三角面片拓扑邻域的快速查询。

The paper introduces an improved data pre-processing method based on R*R*-tree data structure,which can effectively eliminate data points from the training data set that are not crucial for clustering.
