Detailed Description

template<class TPointSet, class TOutput = double, class TCoordRep = double>
class itk::ManifoldParzenWindowsPointSetFunction< TPointSet, TOutput, TCoordRep >

Point set function based on n-dimensional parzen windowing.

This class allows evaluating a function derived from a point set by creating a continuous distribution using manifold parzen windowing. Each point is associated with a Gaussian and local shape can be encoded in the covariance matrix.
