Shape analysis using the Fisher-Rao Riemannian metric: unifying shape representation and deformation
16 years 13 days ago
— We show that the Fisher-Rao Riemannian metric is a natural, intrinsic tool for computing shape geodesics. When a parameterized probability density function is used to represent...
