  • A Variational Model for Joint Motion Estimation and Image Reconstruction 

    Burger, Martin; Dirks, Hendrik; Schönlieb, Carola-Bibiane (Society for Industrial and Applied MathematicsSIAM Journal on Imaging Sciences, 2018-01)
    The aim of this paper is to derive and analyze a variational model for the joint estimation of motion and reconstruction of image sequences, which is based on a time-continuous Eulerian motion model. The model can be set ...

  • Multi-Contrast MRI Reconstruction with Structure-Guided Total Variation 

    Ehrhardt, Matthias Joachim; Betcke, Marta M (Society for Industrial and Applied MathematicsSIAM Journal on Imaging Sciences, 2016-08-04)
    Magnetic resonance imaging (MRI) is a versatile imaging technique that allows different contrasts depending on the acquisition parameters. Many clinical imaging studies acquire MRI data for more than one of these contrasts—such ...
