Abstract
The analysis of shape represented as surface meshes is an important tool in anthropology and biomedicine for the
study of aging, post-treatment development or sexual dimorphism. Most approaches rely on nonrigid registration
using manually placed homologous landmarks, it is however often the case that some regions cannot be landmarked
due to the lack of clear anatomical features. We therefore present a method of analyzing and visualizing
the variability of a set of surface models that does not rely on landmarks for feature matching and uses coherent
point drift (CPD), a nonrigid registration algorithm, instead. Our approach is based on the topology transfer of
one arbitrarily selected base mesh to all other meshes with the use of CPD. The procedure ensures the identical
meanings of corresponding vertices across the sample and allows the use of multivariate statistics even with
shapes that would be difficult to process with methods that rely on landmarks for feature-matching.
