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.

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.

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.
