Detailed Description

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

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

This class derives from SpatialNeighborSubsampler and randomly selects points according to a uniform distribution within the Radius given by SetRadius(radius) as long as that point is also within the RegionConstraint.

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.
