Detailed Description

template<typename TSample, typename TRegion>
class itk::Statistics::SpatialNeighborSubsampler< TSample, TRegion >

A subsampler that selects all points within the specified radius of the query point.

This class derives from RegionConstrainedSubsampler and returns all points within the Radius given by SetRadius(radius) as long as that point is also within the RegionConstraint. In order for this to work, a region corresponding to the Sample must be provided using SetSampleRegion(region)

This class assumes that the instance identifiers in the input sample correspond to the result of ComputeOffset() of the index of the corresponding point in the image region.
