An inexact Newton-Krylov algorithm for constrained diffeomorphic image registration
Andreas Mang, George Biros
We propose numerical algorithms for solving large deformation diffeomorphic image registration problems. We formulate the nonrigid image registration problem as a problem of optima…

An inverse problem formulation for parameter estimation of a reaction diffusion model of low grade gliomas
Amir Gholami, Andreas Mang, George Biros
We present a numerical scheme for solving a parameter estimation problem for a model of low-grade glioma growth. Our goal is to estimate the spatial distribution of tumor concentra…
