Detailed Description
SoSNNFilterProcessing engine
The SoSNNFilterProcessing engine reduces noise while preserving edge content.
For an introduction to image filters, see section Images Filters.
This engine, for Symmetric Nearest Neighbor Filter, is a filter weighted by structural symmetry of a rectangular neighbors window. It computes a local mean, around a central voxel 
, of neighbors voxel gray level considering for each neighbor voxel a value given by:
![\[I_m(y)=\left\{\begin{array}{ll} I(y) & ~\mbox{if $|I(x)-I(y)| < |I(x)-I(y_s)|$} \\ I(y_s) & ~\mbox{if $|I(x)-I(y)| > |I(x)-I(y_s)|$} \\ I(x) & ~\mbox{otherwise} \end{array}\right.\]](form_478.png)
where 
is the neighbor voxel symmetric to 
with respect to .
