Detailed Description

template<class TInputImage, class TOutputImage>
class itk::DerivativeImageFilter< TInputImage, TOutputImage >

Computes the directional derivative of an image. The directional derivative at each pixel location is computed by convolution with a derivative operator of user-specified order.

SetOrder specifies the order of the derivative.

SetDirection specifies the direction of the derivative with respect to the coordinate axes of the image.

Member Function Documentation

template<class TInputImage, class TOutputImage>
void itk::DerivativeImageFilter< TInputImage, TOutputImage >::GenerateData  )  [protected, virtual]
 

Standard pipeline method. While this class does not implement a ThreadedGenerateData(), its GenerateData() delegates all calculations to an NeighborhoodOperatorImageFilter. Since the NeighborhoodOperatorImageFilter is multithreaded, this filter is multithreaded by default.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage, class TOutputImage>
virtual void itk::DerivativeImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion  )  throw (InvalidRequestedRegionError) [virtual]
 

DerivativeImageFilter needs a larger input requested region than the output requested region (larger in the direction of the derivative). As such, DerivativeImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Ignore the image spacing. Use this option if you want derivatives in isotropic pixel space. Default is UseImageSpacingOn.
