Deep neural networks on diffeomorphism groups for optimal shape reparametrization
Celledoni, Elena; Glöckner, Helge; Riseth, Jørgen Nilsen; Schmeding, Alexander (Journal article; Peer reviewed, 2023)One of the fundamental problems in shape analysis is to align curves or surfaces before computing geodesic distances between their shapes. Finding the optimal reparametrization realizing this alignment is a computationally ... -
Gradient-Based Optimization in Shape Analysis for Reparametrization of Parametric Curves and Surfaces
Riseth, Jørgen Nilsen (Master thesis, 2021)I denne oppgaven studerer vi to gradientbaserte optimeringsalgoritmer i formanalyse, for reparametrisering av parametriske kurver og overflater. Den ene algoritmen er en tidligere kjent “gradient descent”-algoritme på ...
