A statistical shape model of the skull developed from a South African population

Abstract

This paper discusses the development of a statistical shape model (SSM) of the skull from a South African population. A total of 16 skulls is used together with a reference from the Basel Face Model. A free-form deformation model is built using the reference model and the squared exponential kernel. The freeform model is used to establish dense correspondence across the skull sample and the in-correspondence skulls are then used to build an SSM. The validity of the SSM is assessed using leave-one-out cross-validation with its generality ranging between 1.47 mm and 1.84 mm and, the specificity ranging between 1.74 mm and 2.11 mm.

MUG500+: Database of 500 high-resolution healthy human skulls and 29 craniotomy skulls and implants

“… The 500 healthy skulls can be used to create an statistical shape model (SSM) for cranial implant design [2] , study the geometry variability of human skulls [3] , [4] , etc. The 29 craniotomy skulls together with the corresponding manually designed cranial implants can serve as an evaluation set for automatic cranial implant design algorithms.…”
