A PDE-based Method for Shape Registration
Esten Nicolai Wøien, Markus Grasmair
In the square root velocity framework, the computation of shape space distances and the registration of curves requires solution of a non-convex variational problem. In this paper,…

Source Conditions for non-quadratic Tikhonov Regularisation
Markus Grasmair
In this paper we consider convex Tikhonov regularisation for the solution of linear operator equations on Hilbert spaces. We show that standard fractional source conditions can be…

Landmark-Guided Elastic Shape Analysis of Human Character Motions
Martin Bauer, Markus Eslitzbichler, Markus Grasmair
Motions of virtual characters in movies or video games are typically generated by recording actors using motion capturing methods. Animations generated this way often need postproc…
