Detailed Description

Shifts constant frequency to center for.

Date:

2000/12/10 20:09:06

Revision:

1.15

Thanks:

Thanks to C. Charles Law who developed this class. 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 floats.

Member Function Documentation

vtkImageFourierCenter* vtkImageFourierCenter::New (    )  [static]

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

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageDecomposeFilter.

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

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageDecomposeFilter.

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

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageDecomposeFilter.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageDecomposeFilter.

void vtkImageFourierCenter::operator= (  const vtkImageFourierCenter &    )  [inline, protected]

Definition at line 73 of file vtkImageFourierCenter.h.

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.
