Total Variation Regularization for X-Ray Tensor Tomography
Proceedings of Fully3D, Newport, USA, June 2015 (bib)

Tensor-valued data is more complex to validly denoise, as these shapes are usually constrained. Considerable efforts have been spent on achieving this for Diffusion Tensor Imaging. A novel tensor-valued imaging modality, X-ray Tensor Tomography (XTT) has recently been presented, where the tensors describe scattering of X-ray beams. In this work, we investigate the applicability of a Total-Variation-based method enforcing the tensors to remain on their manifold.
