Journal ArticleDOI
Automated segmentation of electron tomograms for a quantitative description of actin filament networks.
Alexander Rigort,David Günther,Reiner Hegerl,Daniel Baum,Britta Weber,Steffen Prohaska,Ohad Medalia,Ohad Medalia,Wolfgang Baumeister,Hans-Christian Hege +9 more
TL;DR: An automated procedure for the segmentation of actin filaments is described, which combines template matching with a new tracing algorithm, and the result is a set of lines, each one representing the central line of a filament.
Journal ArticleDOI
Characterizing Molecular Interactions in Chemical Systems
TL;DR: Experiments demonstrate the ability of the first combinatorial algorithm for the automated extraction and characterization of covalent and noncovalent interactions in molecular systems to robustly extract these interactions and to reveal their structural relations to the atoms and bonds forming the molecules.
Journal ArticleDOI
Efficient Computation of 3D Morse-Smale Complexes and Persistent Homology using Discrete Morse Theory
TL;DR: An efficient algorithm that computes the Morse–Smale complex for 3D gray-scale images and allows for the computation of persistent homology for large data on commodity hardware is proposed.
Journal ArticleDOI
Separatrix persistence: extraction of salient edges on surfaces using topological methods
Tino Weinkauf,David Günther +1 more
TL;DR: A novel method for salient edge extraction which does not depend on curvature derivatives is introduced, based on a topological analysis of the principal curvatures and salient edges of the surface are identified as parts of separatrices of the topological skeleton.
Journal ArticleDOI
The Arnold–Winther mixed FEM in linear elasticity. Part I: Implementation and numerical verification☆
TL;DR: In this article, the authors describe the implementation of the symmetric mixed finite element method and its 30×30 local stress stiffness matrices and study the lowest-order scheme for general boundary conditions.
