#include <itkSmoothingQuadEdgeMeshFilter.h>
QuadEdgeMesh Smoothing Filter.
This filter adjusts point coordinates using Laplacian smoothing. The effect is to "relax" the mesh, making the cells better shaped and the vertices more evenly distributed.
For one iteration the location of one vertex is computed as follows:
where is computed by the means of the set functor CoefficientsComputation
This process is then repeated for m_NumberOfIterations (the more iterations, the smoother the output mesh will be).
At each iteration, one can run DelaunayConformingQuadEdgeMeshFilter resulting a more regular (in terms of connectivity) and smoother mesh. Depending on the mesh size and configuration it could be an expensive process to run it at each iterations, especially if the number of iterations is large. Note that one can still run N iterations without DelaunayConformingQuadEdgeMeshFilter, then run this filter and apply this process M times.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
