3D optical flow for large CT data of materials microstructures

T Nogatz, C Redenbach, K Schladitz - Strain, 2022 - Wiley Online Library
We compute three‐dimensional displacement vector fields to estimate the deformation of
microstructural data sets in mechanical tests. For this, we extend the well‐known optical flow …

An operator-splitting approach for variational optimal control formulations for diffeomorphic shape matching

A Mang, J He, R Azencott - Journal of Computational Physics, 2023 - Elsevier
We present formulations and numerical algorithms for solving diffeomorphic shape matching
problems. We formulate shape matching as a variational problem governed by a dynamical …
