Abstract
The Voronoi diagram (VD) is a popular tool for partitioning the suppor t of an image. An algorithm is presented for constructing VD when the seed set, which determines the Voronoi regions, can be modified by add ing and removing seeds. The number of pixels and seeds revisited for u pdating the diagram and the neighbor relationships among seeds is mini mized. A result on cocircular seeds is presented. The adjacency, or du al, graph of the VD is readily obtained. The use of the algorithm for constructing skeletons by influence zones is demonstrated.
