An MBO scheme for minimizing the graph Ohta-Kawasaki functional
Yves van Gennip
We study a graph based version of the Ohta-Kawasaki functional, which was originally introduced in a continuum setting to model pattern formation in diblock copolymer melts and has…
A Max-Cut approximation using a graph based MBO scheme
Blaine Keetch, Yves van Gennip
The Max-Cut problem is a well known combinatorial optimization problem. In this paper we describe a fast approximation method. Given a graph G, we want to find a cut whose size is…
Graph clustering, variational image segmentation methods and Hough transform scale detection for object measurement in images
Luca Calatroni, Yves van Gennip, Carola-Bibiane Schönlieb +2
We consider the problem of scale detection in images where a region of interest is present together with a measurement tool (e.g. a ruler). For the segmentation part, we focus on t…
Deblurring of One Dimensional Bar Codes via Total Variation Energy Minimisation
Rustum Choksi, Yves van Gennip
Using total variation based energy minimisation we address the recovery of a blurred (convoluted) one dimensional (1D) barcode. We consider functionals defined over all possible ba…
The H^{-1}-norm of tubular neighbourhoods of curves
Yves van Gennip, Mark A. Peletier
We study the H^{-1}-norm of the function 1 on tubular neighbourhoods of curves in R^2. We take the limit of small thickness epsilon, and we prove two different asymptotic results.…
