TL;DR本文概述了近期关于形状分析的技术，探讨了以高维空间中的点为形状的方法，借助合适的度量计算给定形状的变形范围，进而比较与分类 3D 对象、计算对象间的平滑变形并模拟与探索形状变异。提出该领域的发展方向及应用前景，涉及数学、统计学、计算机视觉与图形学、医学图像分析等领域。
Abstract
Shape is an important physical property of natural and manmade 3D objects
that characterizes their external appearances. Understanding differences
between shapes and modeling the variability within and across shape classes,
hereinafter referred to as \emph{shape analysis}, are fundamen
