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 >
virtual::itk::LightObject::Pointer itk::DerivativeImageFilter< TInputImage, TOutputImage >::CreateAnother ( void  ) const [virtual]

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.

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.

template<class TInputImage , class TOutputImage >
virtual const char* itk::DerivativeImageFilter< TInputImage, TOutputImage >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage , class TOutputImage >
virtual unsigned int itk::DerivativeImageFilter< TInputImage, TOutputImage >::GetOrder ( ) const [virtual]

template<class TInputImage , class TOutputImage >
virtual bool itk::DerivativeImageFilter< TInputImage, TOutputImage >::GetUseImageSpacing ( ) const [virtual]

Set/Get whether or not the filter will use the spacing of the input image in its calculations

template<class TInputImage , class TOutputImage >
static Pointer itk::DerivativeImageFilter< TInputImage, TOutputImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<class TInputImage , class TOutputImage >
void itk::DerivativeImageFilter< TInputImage, TOutputImage >::operator= ( const Self &  ) [private]

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage , class TOutputImage >
void itk::DerivativeImageFilter< TInputImage, TOutputImage >::PrintSelf ( std::ostream &  os,
Indent  indent 
) const [protected, virtual]

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.

virtual void itk::DerivativeImageFilter< TInputImage, TOutputImage >::SetUseImageSpacing ( bool  _arg) [virtual]

Set/Get whether or not the filter will use the spacing of the input image in its calculations

template<class TInputImage , class TOutputImage >
void itk::DerivativeImageFilter< TInputImage, TOutputImage >::SetUseImageSpacingOff ( ) [inline]

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

Definition at line 104 of file itkDerivativeImageFilter.h.

template<class TInputImage , class TOutputImage >
void itk::DerivativeImageFilter< TInputImage, TOutputImage >::SetUseImageSpacingOn ( ) [inline]

Use the image spacing information in calculations. Use this option if you want derivatives in physical space. Default is UseImageSpacingOn.

template<class TInputImage , class TOutputImage >
itk::DerivativeImageFilter< TInputImage, TOutputImage >::typedef ( Concept::Signed< OutputPixelType >  )

The output pixel type must be signed. Begin concept checking This class requires SignedOutputPixelType in the form of ( Concept::Signed< OutputPixelType > )
