Abstract
This paper presents a new algorithm for non-rigid registration between two doubly-connected regions. Our algorithm is based on harmonic analysis and the theory of optimal mass transport. It assumes an underlining continuum model, in which the total amount of mass is exactly preserved during the transformation of tissues. We use a finite element approach to numerically implement the algorithm.
摘要
本文提出了一种用于两个双连通区域之间非刚性配准的新算法。我们的算法基于调和分析和最优质量传输理论。它假设了一个基础的连续统模型，在该模型中，组织在变换过程中总质量精确守恒。我们使用有限元方法对该算法进行数值实现。
