Abstract:

A method for corresponding the triangulated mesh surface representations of two shapes is presented. The algorithm produces a matching pair of sparse polyhedral approximations, one for each shape surface, using a global Euclidean measure of similarity. A method of surface patch parameterisation is presented and its use in the interpolation of surfaces for the construction of a merged mean shape with a densely triangulated surface is described. Results are presented for the production of a binary tree of merged biological shapes which may be used as a basis for automated landmarking.
