Exponentiation Filters
starstarstarstarstar
Two simple filters are contributed to compute the exponential of an image: the first one to raise the image to the power of a constant, the other one to raise the image to the power of the values provided in another image.

A Generalized Squared Euclidean Distance Transform with Voronoi Maps
starstarstarstarstar
This document describes the implementation of an algorithm that computes a generalization of the distance transform with the squared euclidean metric. The generalization allows for interesting image operators, e.g. a morphologic dilation with euclidean ball [...]

Automated Brain-Tissue Segmentation by Multi-Feature SVM Classification
No opinion
We present a method for automated brain-tissue segmentation through voxelwise classification. Our algorithm uses manually labeled training images to train a support vector machine (SVM) classifier, which is then used for the segmentation of target images. The [...]

Local Shape Analysis using MANCOVA
starstarstarstarstar
Gross shape measures such as volume have been widely used in statistical analysis of anatomical structures. Statistical shape analysis methods have emerged within the last decade to allow for a localized analysis of shape. Most shape analysis frameworks are [...]

Principal Components Analysis of Scalar, Vector, and Mesh Vertex Data
starstarstarstarstar
This document describes a contribution to the Insight Toolkit intended to support the analysis of the principal components of data sets, optionally point data associated with the vertices of a mesh. This paper is accompanied with the source code, input data, [...]

MR Parameter Map Suite: ITK Classes for Calculating Magnetic Resonance T2 and T1 Parameter Maps
starstarstarstarstar
This document describes a suite of new multi-threaded classes for calculating magnetic resonance (MR) T2 and T1 parameter maps implemented using the Insight Toolkit ITK (www.itk.org). Similar to MR diffusion tensor imaging (DTI), MR T2 and T1 parameter maps [...]

Diffeomorphic Demons Using ITK's Finite Difference Solver Hierarchy
starstarstarstarstar
This article provides an implementation of our non-parametric diffeomorphic image registration algorithm generalizing Thirion's demons algorithm. Within the Insight Toolkit (ITK), the demons algorithm is implemented as part of the finite difference solver [...]

Tubular Geodesics using Oriented Flux: An ITK Implementation
starstarstarstarstar
This document describes an ITK implementation of an interactive method for tracing curvilinear structures. The basic tools provided in this framework are an oriented flux-based tubularity measure and a geodesic path tracer that uses the fast marching [...]

Direct Fourier Tomographic Reconstruction Image-To-Image Filter
starstarstarstarstar
We present an open-source ITK implementation of a direct Fourier method for tomographic reconstruction, applicable to parallel-beam x-ray images. Direct Fourier reconstruction makes use of the central-slice theorem to build a polar 2D Fourier space from the [...]

An ITK Implementation of the Symmetric Log-Domain Diffeomorphic Demons Algorithm
starstarstarstarstar
This article provides an implementation of the symmetric log-domain diffeomorphic image registration algorithm, or symmetric demons algorithm for short. It generalizes Thirion's demons and the diffeomorphic demons algorithm. The main practical advantages of [...]

Multidimensional Arrays and the nArray Package
starstarstarstarstar
At the Johns Hopkins University’s Engineering Research Center for Computer-Integrated Surgical Systems and Technology (ERC-CISST) laboratory, we have designed and developed a platformindependent C++ software package, called the nArray library, that provides [...]

Radial Thickness Calculation and Visualization for Volumetric Layers
starstarstarstarstar
Volumetric layers often encountered in medical image analysis are characterized by double and nested bounding surfaces. The thickness of a volumetric layer at a point on the bounding surface is the distance from that point to the opposite surface. There exist [...]

An entropy based multi-thresholding method for semi-automatic segmentation of liver tumors
starstarstarstarstar
Liver cancer is the fifth most commonly diagnosed cancer and the third most common cause of death from cancer worldwide. A precise analysis of the lesions would help in the staging of the tumor and in the evaluation of the possible applicable therapies. In [...]
