Surface Meshes Smoothing
No opinion
This paper describes the implementation of a surface smoothing filter in ITK, based ont he Quad Edge Mesh surface data structure.

Surface Mesh Discrete Curvature Estimators
starstarstarstarstar
Computing local curvatures of a given surface is important for applications, shape analysis, surface segmentation, meshing, and surface evolution. For a given smooth surface (with a given analytical expression which is sufficiently differentiable) curvatures [...]

Efficient N-Dimensional surface estimation using Crofton formula and run-length encoding
starstarstarstarstar
Unlike the measure of the area in 2D or of the volume in 3D, the perimeter and the surface are not easily measurable in a discretized image. In this article we describe a method based on the Crofton formula to measure those two parameters in a discritized [...]

Poisson Surface Reconstruction for VTK
starstarstarstarstar
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 [...]

Surface Mesh Normals Filter
starstarstarstarstar
We have previously developed a new surface mesh data structure in itk (code{itk::QuadEdgeMesh}~cite{itkQE}). In this document we describe a new filter (code{itk::QENormalFilter}) to estimate normals for a given triangular surface mesh in this data structure. [...]

Boolean Operations on Surfaces for VTK
starstarstarstarstar
This document describes an implementation of a filter to perform Boolean operations between surfaces. The filter requires the GNU Triangulated Surface Library GTS to perform the operations. This document is accompanied with the source code, and the xml files [...]

Laplace Beltrami Filter on QuadEdge Meshes
starstarstarstarstar
A contribution to the Insight Toolkit intended to support the process of statistical analysis in Computational Anatomy. The methods included here operate on open or closed triagulated surfaces (represented by a QuadEdgeMesh). The filter assigns basis [...]

Cuberille Implicit Surface Polygonization for ITK
starstarstarstarstar
This article describes an ITK implementation of the "cuberille" method for poloygonization of implicit surfaces. The method operates by dividing the surface into a number of small cubes called cuberilles. Each cuberille is centered at a pixel lying on the [...]

Boolean Operations on Surfaces in VTK Without External Libraries
starstarstarstarstar
We have written a set of classes than enable computation of boolean operations on surface meshes using only VTK classes. In addition to being compatible with the VTK license, our contribution preserves surface mesh topology to the extent possible in boolean [...]

Fast Tracking of the Left Ventricle Using Global Anatomical Affine Optical Flow and Local Recursive Block Matching
No opinion
We present a novel method for segmentation and tracking of the left ventricle (LV) in 4D ultrasound sequences using a combination of automatic segmentation at the end-diastolic frame and tracking using both a global optical flow-based tracker and local block [...]

BioImage Suite: An integrated medical image analysis suite: An update
starstarstarstarstar
BioImage Suite is an NIH-supported medical image analysis software suite developed at Yale. It leverages both the Visualization Toolkit (VTK) and the Insight Toolkit (ITK) and it includes many additional algorithms for image analysis especially in the areas [...]

Point Set Surface Reconstruction for VTK
starstarstarstarstar
This document presents a set of classes (vtkPointSetSurfaceReconstruction, vtkVoxelizePolyData) to produce a surface from an oriented point set. These classes are implemented as VTK filters. A Paraview plugin interface is provided to allow extremely easy [...]

Integration of Geometrical Boundary Conditions on Soft Tissue Characterization under large deformation
starstarstarstarstar
Soft tissue characterization with finite element (FE) modeling is important to develop a realistic model for medical simulation, since it is possible to display complex tool-tissue interactions during medical interventions. However, it is difficult to [...]
