论文摘要
我们开发了一种操作员分裂方法来解决三维空间中表面序列的差异匹配问题。目的是以非常快速的速率平稳匹配，这些序列是从电影中提取的观察到的3D-snapshots的有限序列，记录“软”表面的平滑动态变形。我们已经在卫理公会医院（心脏病学）安装的专有软件中实施了算法，以通过计算机分析非侵入性患者的超声心动图来监测二尖瓣的应变。
We develop an operator splitting approach to solve diffeomorphic matching problems for sequences of surfaces in three-dimensional space. The goal is to smoothly match, at a very fast rate, finite sequences of observed 3D-snapshots extracted from movies recording the smooth dynamic deformations of "soft" surfaces. We have implemented our algorithms in a proprietary software installed at The Methodist Hospital (Cardiology) to monitor mitral valve strain through computer analysis of noninvasive patients' echocardiographies.
