Anisotropic Fanning Aware Low-Rank Tensor Approximation Based Tractography

no code implementations3 Jul 2023 Johannes Grün, Jonah Sieg, Thomas Schultz

Our technical contributions include an initialization scheme for the new parameters, which is based on the Hessian of the low-rank approximation, pre-integration of the required convolution integrals to reduce the computational effort, and representation of the required 3D rotations with quaternions.

Combining Image Space and q-Space PDEs for Lossless Compression of Diffusion MR Images

no code implementations14 Jun 2022 Ikram Jumakulyyev, Thomas Schultz

Diffusion MRI is a modern neuroimaging modality with a unique ability to acquire microstructural information by measuring water self-diffusion at the voxel level.

Fourth-Order Anisotropic Diffusion for Inpainting and Image Compression

no code implementations18 Jun 2020 Ikram Jumakulyyev, Thomas Schultz

Edge-enhancing diffusion (EED) can reconstruct a close approximation of an original image from a small subset of its pixels.

Classification on Large Networks: A Quantitative Bound via Motifs and Graphons

no code implementations24 Oct 2017 Andreas Haupt, Mohammad Khatami, Thomas Schultz, Ngoc Mai Tran

When each data point is a large graph, graph statistics such as densities of certain subgraphs (motifs) can be used as feature vectors for machine learning.
