Detailed Description

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

Shift the zero-frequency components of a Fourier transfrom to the center of the image.

The Fourier transform produces an image where the zero frequency components are in the corner of the image, making it difficult to understand. This filter shifts the component to the center of the image.

Note:
For images with an odd-sized dimension, applying this filter twice will not produce the same image as the original one without using SetInverse(true) on one (and only one) of the two filters.

Member Function Documentation

template<class TInputImage , class TOutputImage >
virtual::itk::LightObject::Pointer itk::FFTShiftImageFilter< 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::CyclicShiftImageFilter< TInputImage, TOutputImage >.

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

Override GenerateData method to set some parameters in the superclass.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage , class TOutputImage >
virtual const bool& itk::FFTShiftImageFilter< TInputImage, TOutputImage >::GetInverse ( ) [virtual]

Set/Get whether the filter must invert the transform or not. This option has no effect if none of the size of the input image is even, but is required to restore the original image if at least one of the dimensions has an odd size.

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

Runtime information support.

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

template<class TInputImage , class TOutputImage >
virtual void itk::FFTShiftImageFilter< TInputImage, TOutputImage >::InverseOff ( ) [virtual]

Set/Get whether the filter must invert the transform or not. This option has no effect if none of the size of the input image is even, but is required to restore the original image if at least one of the dimensions has an odd size.

template<class TInputImage , class TOutputImage >
virtual void itk::FFTShiftImageFilter< TInputImage, TOutputImage >::InverseOn ( ) [virtual]

Set/Get whether the filter must invert the transform or not. This option has no effect if none of the size of the input image is even, but is required to restore the original image if at least one of the dimensions has an odd size.

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

Standard New method.

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

template<class TInputImage , class TOutputImage >
void itk::FFTShiftImageFilter< 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::CyclicShiftImageFilter< TInputImage, TOutputImage >.

template<class TInputImage , class TOutputImage >
void itk::FFTShiftImageFilter< 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.

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

template<class TInputImage , class TOutputImage >
virtual void itk::FFTShiftImageFilter< TInputImage, TOutputImage >::SetInverse ( bool  _arg) [virtual]

Set/Get whether the filter must invert the transform or not. This option has no effect if none of the size of the input image is even, but is required to restore the original image if at least one of the dimensions has an odd size.
