A Riemannian Framework for Tensor Computing

Xavier Pennec, +2 more
- 01 Jan 2006 - 
TL;DR: This paper proposes to endow the tensor space with an affine-invariant Riemannian metric and demonstrates that it leads to strong theoretical properties: the cone of positive definite symmetric matrices is replaced by a regular and complete manifold without boundaries, the geodesic between two tensors and the mean of a set of tensors are uniquely defined.

Automated segmentation of multiple sclerosis lesions by model outlier detection

K. Van Leemput, +4 more
- 01 Aug 2001 - 
TL;DR: A fully automated algorithm for segmentation of multiple sclerosis lesions from multispectral magnetic resonance (MR) images that performs intensity-based tissue classification using a stochastic model and simultaneously detects MS lesions as outliers that are not well explained by the model.

Multimodality image registration by maximization of mutual information

Frederik Maes, +4 more
- 01 Apr 1997 - 
TL;DR: The results demonstrate that subvoxel accuracy with respect to the stereotactic reference solution can be achieved completely automatically and without any prior segmentation, feature extraction, or other preprocessing steps which makes this method very well suited for clinical applications.

A survey of image registration techniques

Lisa Gottesfeld Brown
- 01 Dec 1992 - 
TL;DR: This paper organizes this material by establishing the relationship between the variations in the images and the type of registration techniques which can most appropriately be applied, and establishing a framework for understanding the merits and relationships between the wide variety of existing techniques.

Image matching as a diffusion process: an analogy with Maxwell's demons

Jean-Philippe Thirion
- 01 Sep 1998 - 
TL;DR: The main idea is to consider the objects boundaries in one image as semi-permeable membranes and to let the other image, considered as a deformable grid model, diffuse through these interfaces, by the action of effectors situated within the membranes.

Finite element implementation of incompressible, transversely isotropic hyperelasticity

Jeffrey A. Weiss, +3 more
- 15 Aug 1996 - 
TL;DR: In this article, a three-dimensional constitutive model for biological soft tissues and its finite element implementation for fully incompressible material behavior is presented, along with derivations of the stress and elasticity tensors for a transversely isotropic, hyperelastic material.
