Detailed Description

template<class PixelType = short int, unsigned int NDimension = 3>
class itk::VesselEnhancingDiffusion3DImageFilter< PixelType, NDimension >

Complete rewrite of previous versions, only using itk/vnl routines for derivatives, eigensystem calculations and diffusion. Internally, the input image image is converted to internalprecision (float) for calculation, and converted back when returning the results.

Uses simple forward Euler scheme (explicit) with 3x3x3 stencil, see eg phd of Joachim Weickert for theory and implementation regarding the construction of this discretization scheme. See 'Vessel Enhancing Diffusion', Manniesing, media 2006, for information regarding the construction of the diffusion tensor.

Stores all elements of the Hessian of the complete image during diffusion. An alternative implementation is to only store the scale for which the vesselness has maximum response, and to recalculate the hessian (locally) during diffusion. Also stores the current image, ie at iteration i + temp image, therefore the complete memory consumption approximately peaks at 8 times the input image (input image in float)
The hessian is stored as six individual images, an alternative implementation is to use the itk symmetric second rank tensor as pixeltype (and eg using the class SymmetricEigenAnalysisImage Filter). However, we are lazy, and using this since we rely on vnl datatypes and its eigensystem calculations
note: most of computation time is spent at calculation of vesselness response

9 feb 2009 changed imagetype to precisionimage type of function call, thanks to Mark Rabotnikov
PixelType short, 3D Precision float, 3D
todo
- using parallelism/threading eg over scales
- completely itk-fying, eg eigenvalues calculation
- possibly embedding within itk-diffusion framework
- itk expert to have a look at use of iterators (there must be a potential gain there)
