Image segmentation is a hot topic of research given its applicability as a pre-processing
technique in many image understanding applications. This paper describes the Mumford …

Action minimization and sharp‐interface limits for the stochastic Allen‐Cahn equation

RV Kohn, F Otto, MG Reznikoff… - … on Pure and Applied …, 2007 - Wiley Online Library
We study the action minimization problem that is formally associated to phase transformation

Partial localization, lipid bilayers, and the elastica functional

MA Peletier, M Röger - Archive for rational mechanics and analysis, 2009 - Springer
Partial localization is the phenomenon of self-aggregation of mass into highdensity
structures that are thin in one direction and extended in the others. We give a detailed study …

Segmentation with depth: A level set approach

W Zhu, T Chan, S Esedo g¯ lu - SIAM journal on scientific computing, 2006 - SIAM
Segmentation with depth is the challenging problem of obtaining three dimensional
information from a single two dimensional image. Unlike the standard segmentation …

Sharp-interface limit of the Allen-Cahn action functional in one space dimension
