A generic interpolator for multi-label images
No opinion
We present a generic interpolator for label images. The basic idea is to interpolate each label with an ordinary image interpolator, and return the label with the highest value. This is the idea used by the itk::LabelImageGaussianInterpolateImageFunction [...]

A Simple Command Line Argument Parser
starstarstarstarstar
This document describes the implementation of a simple command line argument parser using the Insight Toolkit ITK. Such a parser may be useful for use in the examples of the ITK. This paper is accompanied with the source code.

Kappa Sigma Clipping
starstarstarstarstar
When an image is mostly composed of background pixels, most of the automatic thresholding methods are failing to produce a relevant threshold. This is mainly caused because one mode is over represented compared to the other in the histogram of the image. [...]

MUSiiC ToolKit 2.0: Bidirectional Real-time Software Framework for Advanced Interventional Ultrasound Research
No opinion
Ultrasound (US) imaging is a popular and convenient medical imaging modality thanks to its mobility, non-ionizing radiation, ease-of-use, and real-time acquisition. Conventional US imaging is frequently integrated with tracking systems and robotic systems in [...]

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 [...]

Mutable Priority Queue Container
starstarstarstarstar
When dealing with functional minimization, or maximization, it can sometimes be solved by a greedy algorithm. To implement greedy algorithm one needs priority queue container, i.e. get for a very low cost the lowest or highest element present in a sorted [...]

Triangular Meshes Delaunay Conforming Filter
starstarstarstarstar
The emph{Delaunay triangulation} is the triangulation of a set of points which maximizes the minimum angle of all angles of the triangles, and thus triangle aspect ratios. So converting a non Delaunay triangulation into a Delaunay triangulation, emph{Delaunay [...]

The Image-based Vascular Analysis Toolkit (IvanTk)
No opinion
This document describes the Image-based Vascular Analysis Toolkit (IvanTk), a set of cross-platform C++ open source software libraries for the detection, extraction and modeling of vessels in 2D/3D medical images based on the Insight Toolkit. We provide an [...]

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 [...]

ITK Image IO interface with Apple iOS
No opinion
We have recently detailed the procedure for building ITK on the iOS. In this work, we contribute itkiOSImageIO , the necessary ITK class that provides the input/output (IO) interface with the repository of images stored on iOS Apple devices, such as the iPod [...]

Non-rigid Groupwise Registration using B-Spline Deformation Model
starstarstarstarstar
In this work, we extend a previously demonstrated entropy based groupwise registration method to include a non-rigid deformation model based on B-splines. We describe an open source implementation of the groupwise registration algorithm using the [...]

Label object representation and manipulation with ITK
starstarstarstarstar
Richard Beare has recently introduced a new filter to efficiently labelize the connected components with ITK, and has also proposed to use the run-length encoding used in that filter to implement some of the most useful binary mathematical morphology [...]

Implementation of a 3D thinning algorithm
starstarstarstarstar
ITK currently comes with a 2D binary thinning (skeletonisation) method, but does not support 3D or higher. This paper documents a new itkBinaryThinningImageFilter3D and recommends to rename the current filter as itkBinaryThinningImageFilter2D. The 3D [...]

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 [...]
