Abstract: Spaces of curves and surfaces or spaces of images are considered as Riemannian manifolds. The talk will develop a calculus on such spaces, which enables

  • the computation of distances via minimizing a Riemannian path energy,
  • interpolation of shapes along geodesic paths,
  • extrapolation via the Riemannian exponential map,
  • detail transfer via parallel transport,
  • key pose interpolation via Riemannian splines, and
  • statistical analysis via Riemannian PCA.
To this end a time discrete calculus is introduced and its convergence is discussed.

Online Seminar "Geometric Analysis"

Series comments: We discuss recent trends related to geometric analysis in a broad sense. The general idea is to solve geometric problems by means of advanced tools in analysis. We will include a wide range of topics such as geometric flows, curvature functionals, discrete differential geometry, and numerical simulation.
