[ITK] [vtkusers] ITK Noise removal filter on VTK file

[Jon Haitz Legarreta]

Dear Majid,
if you are processing a 2D/3D (medical image) volumetric dataset, I'd say
that it'd be easier to just use ITK as a starting point. If you then need
visualization capabilities, then you'd need to use VTK as well.

For resampling, and reslicing purposes, you may want to have a look at
https://itk.org/Doxygen/html/classitk_1_1ResampleImageFilter.html

and the examples
https://itk.org/ITKExamples/src/Filtering/ImageGrid/ResampleAnImage/Documentation.html

For using VTK with medical datasets:
https://lorensen.github.io/VTKExamples/site/Cxx/#medical

For edge preserving noise removal, you can have a look at
https://itk.org/Doxygen/html/classitk_1_1AnisotropicDiffusionImageFilter.html

Edge preserving noise removal is described in Section 2.7.3. of the ITK
Software Guide:
https://itk.org/ItkSoftwareGuide.pdf

For storing your image, ITK tends to use metaimage format:
https://itk.org/Doxygen/html/classitk_1_1MetaImageIO.html

VTK can also write/read it.

HTH,
JON HAITZ


PS: ITK has transitioned to discourse.itk.org as a discussion forum. So if
your question is only about ITK, it would be advisable to post it there.
