Quantifying the Resolution of a Template after Image Registration
Matthias Glock, Thomas Hotz
In many image processing applications (e.g. computational anatomy) a groupwise registration is performed on a sample of images and a template image is simultaneously generated. Fro…
Central limit theorem for intrinsic Frechet means in smooth compact Riemannian manifolds
Thomas Hotz, Huiling Le, Andrew T. A. Wood
We prove a central limit theorem (CLT) for the Frechet mean of independent and identically distributed observations in a compact Riemannian manifold assuming that the population Fr…
Regional estimates of reproduction numbers with application to COVID-19
Jan Pablo Burgard, Stefan Heyder, Thomas Hotz +1
In the last year many public health decisions were based on real-time monitoring the spread of the ongoing COVID-19 pandemic. For this one often considers the reproduction number w…
How much testing and social distancing is required to control COVID-19? Some insight based on an age-differentiated compartmental model
Sara Grundel, Stefan Heyder, Thomas Hotz +3
In this paper, we provide insights on how much testing and social distancing is required to control COVID-19. To this end, we develop a compartmental model that accounts for key as…
Monitoring the spread of COVID-19 by estimating reproduction numbers over time
Thomas Hotz, Matthias Glock, Stefan Heyder +3
To control the current outbreak of the Coronavirus Disease 2019, constant monitoring of the epidemic is required since, as of today, no vaccines or antiviral drugs against it are k…
An algorithm for computing Fréchet means on the sphere
Gabriele Eichfelder, Thomas Hotz, Johannes Wieditz
For most optimisation methods an essential assumption is the vector space structure of the feasible set. This condition is not fulfilled if we consider optimisation problems over t…
