Higher Order Diffusion Tensor Estimation

Estimation of Higher-Order DTI from a given Diffusion Weighted MRI dataset

This script shows how to compute a Higher-order Diffusion Tensor from a given Diffusion-Weighted MRI dataset. The method guarantees that the estimated tensor is positive-definite or at least positive semi-definite. This implementation is based on the article by A. Barmpoutis and B.C. Vemuri, "A Unified Framework for Estimating Diffusion Tensors of any order with Symmetric Positive-Definite Constraints", In the Proceedings of ISBI, 2010
