Statistically-based reorientation of diffusion tensor field
This paper presents a new method for warping of diffusion tensor fields. The proper reorientation of a tensor field requires knowledge of the underlying fiber orientation, which i...

Display of Vector Fields Using a Reaction-Diffusion Model
Effective visualization of vector fields relies on the ability to control the size and density of the underlying mapping to visual cues used to represent the field. In this paper ...

Non-local Image Smoothing By Applying Anisotropic Diffusion Pde's In The Space Of Patches
We design a family of non-local image smoothing algorithms which approximate the application of diffusion PDE's on a specific Euclidean space of image patches. We first map a...

Estimating Orientation Distribution Functions with Probability Density Constraints and Spatial Regularity
High angular resolution diffusion imaging (HARDI) has become an important magnetic resonance technique for in vivo imaging. Current techniques for estimating the diffusion orientat...

A Spin Glass Based Framework to Untangle Fiber Crossing in MR Diffusion Based Tracking
We propose a general approach to the reconstruction of brain white matter geometry from diffusion-weighted data. This approach is based on an inverse problem framework. The optimal...
