Detailed Description

Frequency domain Low pass.

Thanks:
Thanks to C. Charles Law who developed this class.
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));

Member Function Documentation

vtkImageButterworthLowPass* vtkImageButterworthLowPass::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkImageToImageFilter.

virtual const char* vtkImageButterworthLowPass::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

vtkImageButterworthLowPass* vtkImageButterworthLowPass::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

void vtkImageButterworthLowPass::PrintSelf ostream &    os,
vtkIndent    indent
[virtual]
 

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 vtkImageToImageFilter.

virtual void vtkImageButterworthLowPass::SetCutOff float   ,
float   ,
float   
[virtual]
 

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).

virtual void vtkImageButterworthLowPass::SetCutOff float   [3] [virtual]
 

void vtkImageButterworthLowPass::SetCutOff float    v [inline]

float &   ,
float &   
[virtual]
 

virtual void vtkImageButterworthLowPass::GetCutOff float   [3] [virtual]
 

float vtkImageButterworthLowPass::GetXCutOff   [inline]

float vtkImageButterworthLowPass::GetZCutOff   [inline]
 

Definition at line 82 of file vtkImageButterworthLowPass.h.

virtual void vtkImageButterworthLowPass::SetOrder int    [virtual]
 

The order determines sharpness of the cutoff curve.

virtual int vtkImageButterworthLowPass::GetOrder   [virtual]
 

void vtkImageButterworthLowPass::operator= const vtkImageButterworthLowPass &    [inline, protected]
 

Definition at line 93 of file vtkImageButterworthLowPass.h.

void vtkImageButterworthLowPass::ThreadedExecute vtkImageData   inData,
vtkImageData   outData,
int    outExt[6],
int    id
[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.

Reimplemented from vtkImageToImageFilter.
