Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class itk::FFTPadImageFilter< TInputImage, TOutputImage >

Pad an image to make it suitable for an FFT transformation.

FFT filters usually requires a specific image size. The size is decomposed in several prime factors, and the filter only supports prime factors up to a maximum value. This filter automatically finds the greatest prime factor required by the available implementation and pads the input appropriately.

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual::itk::LightObject::Pointer itk::FFTPadImageFilter< TInputImage, TOutputImage >::CreateAnother ( ) 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::PadImageFilterBase< TInputImage, TOutputImage >.

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual void itk::FFTPadImageFilter< TInputImage, TOutputImage >::GenerateOutputInformation ( )
overrideprotectedvirtual

Generate the information describing the output data. The default implementation of this method will copy information from the input to the output. A filter may override this method if its output will have different information than its input. For instance, a filter that shrinks an image will need to provide an implementation for this method that changes the spacing of the pixels. Such filters should call their superclass' implementation of this method prior to changing the information values they need (i.e. GenerateOutputInformation() should call Superclass::GenerateOutputInformation() prior to changing the information.

Reimplemented from itk::ProcessObject.

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual const char* itk::FFTPadImageFilter< TInputImage, TOutputImage >::GetNameOfClass ( ) const
virtual

Runtime information support.

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

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual SizeValueType itk::FFTPadImageFilter< TInputImage, TOutputImage >::GetSizeGreatestPrimeFactor ( ) const
virtual

Set/Get the greatest prime factor allowed on the size of the padded image. The filter increase the size of the image to reach a size with the greatest prime factor smaller or equal to the specified value. The default value is 13, which is the greatest prime number for which the FFT are precomputed in FFTW, and thus gives very good performance. A greatest prime factor of 2 produce a size which is a power of 2, and thus is suitable for vnl base fft filters. A greatest prime factor of 1 or less - typically 0 - disable the extra padding.

template<typename TInputImage , typename TOutputImage = TInputImage>
static Pointer itk::FFTPadImageFilter< TInputImage, TOutputImage >::New ( )

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual void itk::FFTPadImageFilter< TInputImage, TOutputImage >::PrintSelf ( std::ostream &  os,

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.
