学术报告--王小强:Edge-Weighted Centroidal Voronoi Tessellation Based Algorithms for Image Segmentation

发布者:张临杰发布时间:2020-12-04浏览次数:10

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. The application of CVT to the Image Segmentation is the traditional k-means algorithm. Here we extend the CVT method to the Edge-Weithed CVT method. The new algorithm produces segmentations that minimize a total energy: a sum of the classic CVT energy and the weighted length of cluster boundaries. The EWCVT method is easy in implementation, fast in computation, and natural for any number of clusters.
