[Insight-users] Smoothing displacements over a surface

[Andriy Fedorov]

Since no-one replied, let me update this thread with what I
researched, in case comes across the same question.

I didn't find any suitable filter in ITK/VTK.

Here's one paper that discusses the topic:

Y.Shen, K.E.Barner "Fuzzy vector median-based surface smoothing" IEEE
Transactions on Visualization and Computer Graphics v.10(3),
pp.252-265, 2004

Implementation of the basic smoothing approaches described in this
paper is quite straightforward using the neighborhood iterators
available in QuadEdge mesh.
