This document presents a GUI application to manually select corresponding points in two data sets. The data sets can each be either an image or a point cloud. If both data sets are images, the functionality is equivalent to Matlab's 'cpselect' function. There [...]

K-Means clustering is an excellent technique for clustering points when the number of clusters is known. We present a implementation (vtkKMeanClustering) of the algorithm written in a VTK context. We also implement the K-Means++ initialization method which [...]

This document presents a set of classes to enable operations on itkPointSet objects. In particular, itkTransformPointSetFilter allows a transformation to be applied to a set of points. We propose these classes as addition to the Insight Toolkit ITK.

This document presents a set of classes which implement a region growing algorithm whose criterion for growth is different than existing ITK region growing algorithms. The region is grown into the query pixel based only on the difference between the query [...]

This technical report describes how to use Insight Toolkit to perform elementary ventricle segmentation on data from the Designed Database of MR Brain Images of Healthy Volunteers hosted at MIDAS.

This document describes an example implementation of segmenting the ventricles of the brain using the Insight Toolkit. Ventricle segmentation is done using the simple confidence connected region growing algorithm. Included with this paper is the source [...]

This document presents a set of classes to read a PTX file (a common file format produced by LiDAR scanners) into an itkMesh object. We propose these classes as addition to the Insight Toolkit ITK (www.itk.org).

This document presents an implementation of a stratified mesh sampling algorithm in the VTK framework. This code was adapted directly from the original implementation by Diego Nehab, with permission. We present a class, vtkStratifiedSampling, which uniformly [...]

An implementation of the minimum error thresholding algorithm is presented. In this implementation, two versions of the minimum error thresholding algorithm are made available, one utilizing a Gaussian- and the other utilizing a Poisson- mixture model. Two [...]

This document presents an implementation of the Poisson surface reconstruction algorithm in the VTK framework. (This code was, with permission, adapted directly from the original implementation by Kazhdan, Bolitho, and Hugues. The original implementation can [...]
