Documentation for vtkImageButterworthLowPass

vtkImageButterworthLowPass - Frequency domain Low pass.

Description:

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

Detailed Method Descriptions:

Set/Get the cutoff frequency for each axis. The values are specified in the order X, Y, Z, Time. Units: Cycles per world unit (as defined by the data spacing).
