Barnes-Hut Approximation for Point SetGeodesic Shooting
Jiancong Wang, Long Xie, Paul Yushkevich +1
Geodesic shooting has been successfully applied to diffeo-morphic registration of point sets. Exact computation of the geodesicshooting between point sets, however, requiresO(N2) c…

Diffeomorphic Medial Modeling
Paul A. Yushkevich, Ahmed Aly, Jiancong Wang +4
Deformable shape modeling approaches that describe objects in terms of their medial axis geometry (e.g., m-reps [Pizer et al., 2003]) yield rich geometrical features that can be us…
