<DIV><FONT face=Arial size=2>Dear All,<BR> </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I used vtkbutterworthLowPass filter through
VtkImageFFT.But I feel that I am getting only the FFT output. I am not
getting the ButterworthLowPass filter output.In my code, First I get the pixel
data from an image and storing in some buffer. After that we are importing
the buffer using the "vtkImageImport". Giving the importer output to the
"vtkImageFFT".Then giving output of the "vtkImageFFt" <BR>class to the
"vtkImageButterworthLowPass" class. Then the output of this class has
given to the "vtkImageRFFT" as input. This class output is given to the
"vtkImageExporter" as input.<BR>When I run this filter then the programing is
closing itself by giving the error message.<BR>Can any one please tell me what
parameters and methods I have to use in "vtkButterworthLowPass" class.
Here I am producing my code. <BR>
<BR> vtkImageButterworthLowPass *lowPass =
ImageButterworthLowPass :: New();<BR> lowPass -> SetInput(fft ->
GetOutput());<BR> lowPass -> SetOrder(3);<BR> lowPass ->
SetXCutOff(0.02);<BR> lowPass -> SetYCutOff(0.02);<BR> lowPass
-> ReleaseDataFlagOff();<BR> <BR> vtkImageRFFT *rfft =
vtkImageRFFT::New();<BR> rfft->SetDimensionality ( 2
);<BR> rfft->SetInput( lowPass->GetOutput() );</FONT></DIV><FONT
