A Variational Shape Optimization Approach for Image Segmentation with a Mumford--Shah Functional
We introduce a novel computational method for a Mumford-Shah functional, which decomposes a given image into smooth regions separated by closed curves. Casting this as a shape opti...

Twelve Ways to Fool The Masses when Describing Mesh Generation Performance
Mesh generation for finite element analysis is far from a solved problem. Although several automatic meshing algorithms exist, other difficulties of setting up a problem for finit...

Recovery of Soft Tissue Object Deformation from 3D Image Sequences Using Biomechanical Models
The estimation of soft tissue deformation from 3D image sequences is an important problem in a number of fields such as diagnosis of heart disease and image guided surgery. In thi...

Parallel Edge-Based Inexact Newton Solution of Steady Incompressible 3D Navier-Stokes Equations
The parallel edge-based solution of 3D incompressible Navier-Stokes equations is presented. The governing partial differential equations are discretized using the SUPG/PSPG stabili...

Refinement and Hierarchical Coarsening Schemes for Triangulated Surfaces
We present a refinement and a coarsening (also simplification or decimation) algorithm for the adaptive representation of bivariate functions. The algorithms have proved to be eff...
