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

static vtkImageButterworthLowPass* vtkImageButterworthLowPass::New  )  [static]

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

Reimplemented from vtkAlgorithm.

virtual const char* vtkImageButterworthLowPass::GetClassName  )  [virtual]

Reimplemented from vtkThreadedImageAlgorithm.

static int vtkImageButterworthLowPass::IsTypeOf const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

virtual int vtkImageButterworthLowPass::IsA const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkThreadedImageAlgorithm.
