Guided Diffusion Tensor Tractography with GTRACT: A Validation Study
No opinion
A novel fiber tracking algorithm (GTRACT) was developed to enhance tracking through ambiguous regions where cross fibers, fiber merging or fanning may be occurring. The software was developed using several cross platform open-source toolkits (ITK, VTK, and [...]

Tensor Spectral Matching of Diffusion Weighted Images
No opinion
Very preterm birth coincides with a period of major development in the brain, with striking changes in volume, cortex folding and significant change at the microstructural level. Diffusion MRI is sensitive to motion of water on the scale of microns, allowing [...]

An ITK Class that Splits Multi-Component Images
starstarstarstarstar
This document describes the implementation of a class for the Insight Toolkit (ITK) that takes an image with multi-component pixels and outputs a scalar image for each component. This can be useful when examining images of vectors, tensors, etc. This filter [...]

Multilocal Creaseness Measure
starstarstarstarstar
This document describes the implementation using the Insight Toolkit of an algorithm for detecting creases (ridges and valleys) in N-dimensional images, based on the Local Structure Tensor of the image. In addition to the filter used to calculate the [...]

Implementation of local structure tensor and enhancement anisotropic diffusion filters in ITK
starstarstarstarstar
This paper describes implementation of local structure tensor and anisotropic enhancement diffusion filters using the Insight Toolkit. The anisotropic diffusion filters are implemented using ITK's finite difference solver framework. The filters are used to [...]

A Novel Information-Theoretic Point-Set Measure Based on the Jensen-Havrda-Charvat-Tsallis Divergence
starstarstarstarstar
A novel point-set registration algorithm was proposed in [6] based on minimization of the Jensen-Shannon divergence. In this contribution, we generalize this Jensen-Shannon divergence point-set measure framework to the Jensen-Havrda-Charvat-Tsallis [...]
