Regularized Positive-Definite Fourth Order Tensor Field Estimation from DW-MRI
In Diffusion Weighted Magnetic Resonance Image (DW-MRI) processing, a 2(nd) order tensor has been commonly used to approximate the diffusivity function at each lattice point of the DW-MRI data. From this tensor approximation, one can compute useful scalar quantities (e.g. anisotropy, mean diffusivit...
