Résumé
In this paper, we present the cross-validation of three deformable template superimposition techniques a,b and c, used to study 3D CT images of the bony skull. Method (a) relies on the manual identification by anatomists of anthropometric landmarks, method (b) on “crest lines”, which have a pure geometric definition, and method (c) is based on 3D non-rigid intensity based matching. We propose to define and compute a distance between methods a, b, c, and also to compute three representations I a , Ī b , Ī c of an “average” skull model based superimposition via these three methods. The overall aim is to determine if the three methods, all developed independently, give mutually coherent image superimposition results.
