Detailed Description

template<typename TInputImage, typename TCoordRep = float>
class itk::CovarianceImageFunction< TInputImage, TCoordRep >

Calculate the covariance matrix in the neighborhood of a pixel in a Vector image.

Calculate the covariance matrix over the standard 8, 26, etc. connected neighborhood. This calculation uses a ZeroFluxNeumannBoundaryCondition.

If called with a ContinuousIndex or Point, the calculation is performed at the nearest neighbor.

This class is templated over the input image type and the coordinate representation type (e.g. float or double).
