Detailed Description

Shifts constant frequency to center for display.

Is used for dispaying images in frequency space. FFT converts spatial images into frequency space, but puts the zero frequency at the origin. This filter shifts the zero frequency to the center of the image. Input and output are assumed to be doubles.

vtkImageFourierCenter* vtkImageFourierCenter::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkAlgorithm.

virtual const char* vtkImageFourierCenter::GetClassName ( ) [virtual]

Construct an instance of vtkImageDecomposeFilter filter with default dimensionality 3.
Reimplemented from vtkImageDecomposeFilter.

int vtkImageFourierCenter::IsTypeOf ( const char * type ) [static]

Construct an instance of vtkImageDecomposeFilter filter with default dimensionality 3.
Reimplemented from vtkImageDecomposeFilter.

virtual int vtkImageFourierCenter::IsA ( const char * type ) [virtual]

Construct an instance of vtkImageDecomposeFilter filter with default dimensionality 3.
Reimplemented from vtkImageDecomposeFilter.

vtkImageFourierCenter* vtkImageFourierCenter::SafeDownCast ( vtkObject * o ) [static]

Construct an instance of vtkImageDecomposeFilter filter with default dimensionality 3.
Reimplemented from vtkImageDecomposeFilter.

virtual void vtkImageFourierCenter::IterativeExecuteData ( vtkImageData * in,

vtkImageData * out

) [inline, virtual]

This is an internal method that should not be called by the user.
Implements vtkImageIterateFilter.
Definition at line 53 of file vtkImageFourierCenter.h.
References vtkImageToImageFilter::MultiThread().

void vtkImageFourierCenter::ComputeInputUpdateExtent ( int inExt[6],

int outExt[6]

) [protected, virtual]

Reimplemented from vtkImageIterateFilter.

void vtkImageFourierCenter::ThreadedExecute ( vtkImageData * inData,

vtkImageData * outData,

int outExt[6],

int threadId

) [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.
Reimplemented from vtkImageToImageFilter.
