An ITK implementation of the Normalized Gradient Field Image to Image Metric
No opinion
This article describes the ITK implementation of a Normalized Gradient Fields based image-to-image metric. Some properties of the metric are discussed and example registrations are presented.

Voxel Value Ratio Variance Image Registration Metric for the Insight Toolkit
starstarstarstarstar
This document describes a cost function, or metric, for use in image registration using the Insight Toolkit. The RatioVarianceImageToImageMetric class implements a metric which is calculated from the variance of the ratios of voxel values of the moving and [...]

Mattes’ Mutual Information Metric for Multimodality Registration of DESS and T2 Mapped Knee Articular MR Sequences
No opinion
Registration of multiple MR sequences remains a challenging problem. The Insight Toolkit (ITK) implements the Mattes’ mutual information metric for multimodality registration. Here, example source code, data, and executable files to implement the Mattes’ [...]

Incorporating Metric Flows and Sparse Jacobian Transformations in ITK
No opinion
Various metrics have been proposed in the literature for performing intrinsic automatic image to image registration. Among these measures, mutual information is a very popular one because of its robustness and accuracy for a wide variety of applications. In [...]

An ITK-based Implementation of the Stochastic Rank Correlation (SRC) Metric
starstarstarstarstar
Recently, Birkfellner et al. proposed a novel image-to-image merit function (stochastic rank correlation, SRC) for robust intensity-based 2D/3D image registration. In this work, we summarize the basic idea of SRC, and present a generic ITK-based [...]

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 [...]

An ITK-Based Framework for 2D-3D Registration with Multiple Fixed Images
starstarstarstarstar
This document describes an extension of the Insight Toolkit (ITK, www.itk.org) for 2D-3D registration with multiple fixed images, that is, registration of a three-dimensional dataset to a group of fixed planar projections. 2D-3D registration is possible with [...]
