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

and the examples

For using VTK with medical datasets:

For edge preserving noise removal, you can have a look at

Edge preserving noise removal is described in Section 2.7.3. of the ITK
Software Guide:

For storing your image, ITK tends to use metaimage format:

VTK can also write/read it.


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.
