报告摘要：

Centroidal Voronoi tessellations (CVTs) are special Voronoi tessellations having the property that 

the generators of the Voronoi tessellation are also the centers of mass, with respect to a given 

density function, of the corresponding Voronoi cells. In this talk, we will extend the classic CVT 

methods to the Edge-weighted CVT and apply it to the image segmentation. It shows great advantage 

compared to other image segmentation algorithms. We will further extend it to the Local Variation-EWCVT, 

which can be used to handle the non-homogeneous images. And we will also apply EWCVT to the Superpixels. 

Experiments and results will be given in this talk.
