This script shows how to compute the Diffusion Kurtosis (DKI) Coefficients from a given Diffusion-Weighted MRI dataset. The script implements several fitting methods with various constraints from the article by A. Barmpoutis and J. Zhuo "Diffusion Kurtosis Imaging: Robust Estimation from DW-MRI... Platforms: Matlab

This script shows how to compute a Diffusion Tensor (DTI) from a given DW-MRI (Diffusion-Weighted MRI) dataset. The method guarantees that the estimated tensor is positive-definite or at least positive semi-definite. The implementation is based on the article by A. Barmpoutis and B.C. Vemuri, "A...

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... Platforms: Matlab

This method computes an accurate continuous approximation of the DW-MRI signal using adaptive kernels (A. Barmpoutis et al. "Adaptive kernels for multi-fiber reconstruction", In the Proceedings of IPMI, 2009). The approximation is based on Fig. 3 of the article which shows the plot of the DW-MRI... Platforms: Matlab

tensorRelightingDemo.m demonstrates the use of the Cartesian Tensor basis for facial Apparent BRDF (ABRDF) estimation and subsequent relighting. Given a few images of a face under different point source illuminations, the included code for ABRDF estimation can interpolate and extrapolate them to... Platforms: Matlab
