Equivariant Eikonal Neural Networks: Grid-Free, Scalable Travel-Time Prediction on Homogeneous Spaces
Alejandro GarcÃa-Castellanos, David R. Wessels, Nicky J. van den Berg +3
We introduce Equivariant Neural Eikonal Solvers, a novel framework that integrates Equivariant Neural Fields (ENFs) with Neural Eikonal Solvers. Our approach employs a single neura…

Connected Components on Lie Groups and Applications to Multi-Orientation Image Analysis
Nicky J. van den Berg, Olga Mula, Leanne Vis +1
We develop and analyze a new algorithm to find the connected components of a compact set from a Lie group endowed with a left-invariant Riemannian distance. For a given $δ…

Crossing-Preserving Geodesic Tracking on Spherical Images
Nicky J. van den Berg, Finn M. Sherry, Tos T. J. M. Berendschot +1
In image analysis one often encounters spherical images, for instance in retinal imaging. The behavior of the vessels in the retina is an indicator of several diseases. To automate…
