Member Function Documentation

virtual bool itk::FFTComplexToComplexImageFilter< TImage >::FullMatrix ( ) [protected, pure virtual]

Implemented in itk::FFTWComplexToComplexImageFilter< TImage >.

template<class TImage >

virtual void itk::FFTComplexToComplexImageFilter< TImage >::GenerateInputRequestedRegion ( void ) [protected, virtual]

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierachy. Up till now, the base assumption has been that the largest possible region will be requested of the input.

This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types.

Customized object creation methods that support configuration-based selection of FFT implementation.

Default implementation is FFTW.

Reimplemented from itk::Object.

template<class TImage >

void itk::FFTComplexToComplexImageFilter< TImage >::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.
