Visual analytics for spatial clustering

摘要

A computerized clustering method. The method comprises receiving a spatial point dataset comprising a plurality of spatial points in a space, heuristically calculating, using a processor, a plurality of α-shape based segmentations such that each of the plurality of α-shape based segmentations defines a plurality of polygonal areas that cluster the plurality of spatial points in a plurality of clusters which collectively bounds the plurality of spatial points, presenting to an operator in each sequential iteration of a plurality of sequential iterations another of the plurality of α-shape based segmentations, and selecting by the operator one or more of the plurality of α-shape based segmentations.

1. A computerized clustering method, comprising:
receiving a spatial point dataset comprising a plurality of spatial points in a space; heuristically calculating, using a processor, a plurality of α-shape based segmentations such that each of said plurality of α-shape based segmentations defines a plurality of polygonal areas that cluster said plurality of spatial points in a plurality of clusters which collectively bounds said plurality of spatial points; presenting to an operator in each sequential iteration of a plurality of sequential iterations another of said plurality of α-shape based segmentations; and selecting by said operator at least one of said plurality of α-shape based segmentations.
