* @class vtkImageFourierCenter
|
||
|
|
* @brief 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.
