. 介绍了一种近似多相分离界面平均曲率运动的算法——对Merriman-Bence-Osher (MBO)阈值法的改进。我们采用参考向量的变分方法,将esedoglu - ruth - tsai的再距离方案推广到多相情况。我们研究了它在克服众所周知的MBO时间和非自适应网格的网格限制方面的效率。
. We introduce an algorithm for approximating mean curvature motion of interfaces separating multiple phases – a modification of the Merriman-Bence-Osher (MBO) thresholding method. We extend Esedoglu-Ruuth-Tsai’s redistancing scheme to the multiphase case by adopting a variational method using reference vectors. We look at its efficiency in overcoming the well-known MBO time and grid restrictions on non-adaptive meshes.
