Anisotropic mesh adaptation for region-based segmentation accounting for image spatial information

no code implementations • 19 Dec 2021 • Matteo Giacomini, Simona Perotto

The methodology relies on a split Bregman algorithm for the minimisation of a region-based energy functional and on an anisotropic recovery-based error estimate to drive mesh adaptation.
