Detailed Description

template<class TInputImage>
class itk::FullToHalfHermitianImageFilter< TInputImage >

Reduces the size of a full complex image produced from a forward discrete Fourier transform of a real image to only the non-redundant half of the image.

In particular, this filter reduces the size of the image in the first dimension to $\lfloor N/2 \rfloor + 1$ .

Member Function Documentation

template<class TInputImage >

virtual::itk::LightObject::Pointer itk::FullToHalfHermitianImageFilter< TInputImage >::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 >

virtual void itk::FullToHalfHermitianImageFilter< TInputImage >::GenerateInputRequestedRegion ( ) [protected, virtual]

This class requires the entire input.

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

template<class TInputImage >

virtual void itk::FullToHalfHermitianImageFilter< TInputImage >::GenerateOutputInformation ( ) [protected, virtual]

The output is a different size from the input.

Reimplemented from itk::ProcessObject.

template<class TInputImage >

virtual const char* itk::FullToHalfHermitianImageFilter< TInputImage >::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

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

template<class TInputImage >

static Pointer itk::FullToHalfHermitianImageFilter< TInputImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<class TInputImage >

void itk::FullToHalfHermitianImageFilter< TInputImage >::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, TInputImage >.

template<class TInputImage >

void itk::FullToHalfHermitianImageFilter< TInputImage >::ThreadedGenerateData	(	const OutputImageRegionType &	outputRegionForThread,
		ThreadIdType	threadId
	)		`[protected, virtual]`

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData(). This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).
