Equilibrated Warping: Finite Element Image Registration with Finite Strain Equilibrium Gap Regularization

Image processing, in particular image registration for motion tracking, is playing an important role in biomedical imaging (Tobon-Gomez et  al., 2013; Sotiras et al., 2013) and in other domains such as materials and mechanical engineering (Sutton and Hild, 2015). However, despite important progress made in the past decades, robustness, efficiency and precision of the existing methods must still be improved to translate them into medi cal and engineering applications. In this paper we propose a novel regularization approach that has a strong mechanical basis, and apply it to finite element-based image registration problems.
