Detailed Description

template<class TInputImage, class TOutputImage = Image< std::complex<typename TInputImage::PixelType>, TInputImage::ImageDimension>>
class itk::FFTWRealToHalfHermitianForwardFFTImageFilter< TInputImage, TOutputImage >

FFTW-based forward Fast Fourier Transform.

This filter computes the forward Fourier transform of an image. The implementation is based on the FFTW library.

This filter is multithreaded and supports input images of any size.

In order to use this class, USE_FFTWF must be set to ON in the CMake configuration to support float images, and USE_FFTWD must set to ON to support double images.

This implementation was taken from the Insight Journal paper: http://hdl.handle.net/10380/3154 or http://insight-journal.com/browse/publication/717

typedef fftw::Proxy< InputPixelType > itk::FFTWRealToHalfHermitianForwardFFTImageFilter< TInputImage, TOutputImage >::FFTWProxyType

The proxy type is a wrapper for the FFTW API. Because the proxy is defined only for double and float, trying to use any other pixel type is unsupported, as is trying to use double if only the float FFTW version is configured in, or float if only double is configured.

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.

virtual void itk::FFTWRealToHalfHermitianForwardFFTImageFilter< TInputImage, TOutputImage >::GenerateData ( )
protectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.
