First-Order Indicators for the Estimation of Discrete Fractures in Porous Media
Hend Ben Ameur, Guy Chavent, Cheikh Fatma +3
Faults and geological barriers can drastically affect the flow patterns in porous media. Such fractures can be modeled as interfaces that interact with the surrounding matrix. We p…

Image Segmentation with Multidimensional Refinement Indicators
Hend Ben Ameur, Guy Chavent, Francois Clément +1
We transpose an optimal control technique to the image segmentation problem. The idea is to consider image segmentation as a parameter estimation problem. The parameter to estimate…

The Multi-Dimensional Refinement Indicators Algorithm for Optimal Parameterization
Hend Ben Ameur, François Clément, Pierre Weis +1
The estimation of distributed parameters in partial differential equations (PDE) from measures of the solution of the PDE may lead to under-determination problems. The choice of a…
