比较生物形状的不同寻常的策略是使用某种形式的两种形式的叠加，然后观察形状变化时的“残差”。在本文中，我将仔细研究这一总体策略，并指出一些微妙但固有且重要的陷阱。此外，还提出了一种基于欧氏距离矩阵表示的替代方法。它既适用于二维物体，也适用于三维物体。
The unusual strategy for comparing biological shapes is to use some kind of superimposition of the two forms under study and then look at the "residuals" as the shape change. In this paper, I take a careful look at this general strategy and point out some subtle but inherent and important pitfalls. Additionally an alternative approach based on Euclidean Distance Matrix representation is presented. It is applicable to two- as well as three-dimensional objects.
