Detailed Description

template<class TInputImage, class 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).

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.
