ItkQuadEdgeMesh: A Discrete Orientable 2-Manifold Data Structure for Image Processing
No opinion
There is nowadays an increasing need in interaction between discrete surfaces (2-manifolds) and images. More specifically, segmentation and registration of n-dimensional images are taking advantage of a priori geometrical information, most often provided as [...]

Iterative Smoothing of Field Data in Spherical Meshes
starstarstarstarstar
This document describes a contribution to the Insight Toolkit intended to smooth the values of Field data associated with the nodes of a Spherical Mesh. The Mesh Smoothing filters contributed here do not modify the geometry or the topology of the Mesh. They [...]

Perturbing Mesh Vertices with Additive Gaussian Noise
No opinion
This brief document provides an introduction to an external ITK module, DVMeshNoise. This module provides classes for perturbing the positions of the vertices of either an itk::Mesh or itk::QuadEdgeMesh with Gaussian noise. This may be useful in testing the [...]

Rotational Registration of Spherical Surfaces Represented as QuadEdge Meshes
starstarstarstarstar
This document describes a contribution to the Insight Toolkit intended to support the process of registering two Meshes. The methods included here are restricted to Meshes with a Spherical geometry and topology, and with scalar values associated to their [...]

Exact Geometrical Predicate: Point in circle
starstarstarstarstar
This document describes the implementation in ITK of the "point in circle" geometrical predicate. Based on Jonathan Shewchuk's work which implements an exact version of the predicate using standard floating point types and arithmetic, the implementation [...]

Walk In A Triangulation : Straight Walk
starstarstarstarstar
This document describes the implementation in ITK of the Straight Walk in a Triangulation algorithm proposed by Devillers et al. Using the exact discrete geometrical orientation predicate, and the itk::QuadEdgeMesh API of ITK, we propose an efficient [...]

A Leica PTX Reader for VTK
starstarstarstarstar
Leica LiDAR scanners output points in the PTX file format. It is often useful to convert this format to a standard VTK point cloud or mesh format before processing. We propose a new class, vtkPTXReader, to provide this functionality.

Tetrahedral mesh generation for medical imaging
starstarstarstarstar
We describe the open source implementation of an adaptive tetrahedral mesh generator particularly targeted for non-rigid FEM registration of MR images. While many medical imaging applications require robust mesh generation, there are few codes available. [...]
