Automation can provide significant performance improvements
in digital manufacturing systems that customize
shapes of implants and prosthetic devices to the anatomy of
a patient. The challenge, however, lies in the ability of an
automatic solution to adapt to anatomical variations of a
given object category. This paper presents a hierarchical
framework that generalizes the digital design of anatomical
surface models in terms of a small number of prototypes.
The latter are derived from the local shape information
of constituent parts via shape matching and clustering
and then associated with one operation that dictates how
a shape undergoes modification. We demonstrate the proposed
technique through application to typical hearing aid
design operations with promising results.
