Directional sinogram inpainting for limited angle tomography
In this paper we propose a new joint model for the reconstruction of tomography data under
limited angle sampling regimes. In many applications of tomography, eg electron …

Regularization of inverse problems via time discrete geodesics in image spaces
S Neumayer, J Persch, G Steidl - Inverse Problems, 2019 - iopscience.iop.org
This paper addresses the solution of inverse problems in imaging given an additional
reference image. We combine a modification of the discrete geodesic path model for image …

Invertibility and stability for a generic class of radon transforms with application to dynamic operators
S RabieniaHaratbar - Journal of Inverse and Ill-Posed Problems, 2019 - degruyter.com
Let X be an open subset of ℝ 2. We study the dynamic operator, 𝒜, integrating over a family
of level curves in X when the object changes between the measurement. We use analytic …
