Detailed Description

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

Member Function Documentation

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

static int vtkImageButterworthLowPass::IsTypeOf ( const char *  name) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

virtual int vtkImageButterworthLowPass::IsA ( const char *  name) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkImageButterworthLowPass::PrintSelf ( ostream &  os,
vtkIndent  indent

vtkInformationVector **  inputVector,
vtkInformationVector outputVector,
vtkImageData ***  inData,

int  extent[6],
int  threadId 
) [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.
