// .NAME vtkImageIdealHighPass - Simple frequency domain band pass.
|
|
// .SECTION Description
|
|
// This filter only works on an image after it has been converted to
|
|
// frequency domain by a vtkImageFFT filter. A vtkImageRFFT filter
|
|
// can be used to convert the output back into the spatial domain.
|
|
// vtkImageIdealHighPass just sets a portion of the image to zero. The sharp
|
|
// cutoff in the frequence domain produces ringing in the spatial domain.
|
|
// Input and Output must be doubles. Dimensionality is set when the axes are
|
|
// set. Defaults to 2D on X and Y axes.
