Detailed Description

Frequency domain high pass.

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. vtkImageButterworthHighPass the frequency components around 0 are attenuated. Input and output are in doubles, with two components (complex numbers). out(i, j) = 1 / (1 + pow(CutOff/Freq(i,j), 2*Order));
