Statistical Shape Model of Variability and Spatial Relationships
Résumé
In this paper we model shape objects variability and spatial relationships between characteristics of this object. What is an object? We consider that an object is a set of shapes and points. We establish here a formalism unifying shapes and points by approximating shape contours by composite B'ezier curves. These are equivalent to their control points. We then propose a non linear invariant statistical model and we learn the average object, it's variability and relationships. We finally evaluate our methodology in cephalometry, by modeling anatomical structures and points.
