摘要

提出了一种利用GPU计算质心Voronoi镶嵌的新算法。它以Lloyd方法的迭代方法为基础,同时很好地考虑了用较少的迭代实现快速收敛和在每次迭代内实现快速计算这两大挑战。我们的算法实现可以在数百毫秒的时间内完成大图像的计算,并且比之前在最先进的GPU上的所有工作都要快。因此,现在更容易将质心Voronoi镶嵌集成到交互式应用程序中。

Computing Centroidal Voronoi Tessellation Using the GPU
We propose a novel algorithm to compute centroidal Voronoi tessellation using the GPU. It is based on the iterative approach of Lloyd’s method while having good considerations to address the two major challenges of achieving fast convergence with few iterations, and at the same time achieving fast computation within each iteration. Our implementation of the algorithm can complete the computation for a large image in the order of hundreds of milliseconds and is faster than all prior work on a state-of-the-art GPU. As such, it is now easier to integrate centroidal Voronoi tessellations into interactive applications.
