Detailed Description

template<typename TInputImage, typename TOutputImage = TInputImage>
class itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >

Computes the Laplacian of Gaussian (LoG) of an image.

Computes the Laplacian of Gaussian (LoG) of an image by convolution with the second derivative of a Gaussian. This filter is implemented using the recursive gaussian filters.

Member Function Documentation

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual::itk::LightObject::Pointer itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::CreateAnother ( void  ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

template<typename TInputImage , typename TOutputImage = TInputImage>
void itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::EnlargeOutputRequestedRegion ( DataObject *  ) [protected, virtual]

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region.

Reimplemented from itk::ProcessObject.

template<typename TInputImage , typename TOutputImage = TInputImage>
void itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GenerateData ( void  ) [protected, virtual]

Reimplemented from itk::ImageSource< TOutputImage >.

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual const char* itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GetNameOfClass ( ) const [virtual]

Runtime information support.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage , typename TOutputImage = TInputImage>
virtual bool itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::GetNormalizeAcrossScale ( ) const [virtual]

Define which normalization factor will be used for the Gaussian

See also:
RecursiveGaussianImageFilter::SetNormalizeAcrossScale
template<typename TInputImage , typename TOutputImage = TInputImage>
static Pointer itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<typename TInputImage , typename TOutputImage = TInputImage>
void itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::operator= ( const Self &  ) [private]

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.

Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage , typename TOutputImage = TInputImage>
void itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::PrintSelf ( std::ostream &  os,
Indent  indent 
) const [protected, 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 itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<typename TInputImage , typename TOutputImage = TInputImage>
void itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetNormalizeAcrossScale ( bool  normalizeInScaleSpace)

Define which normalization factor will be used for the Gaussian

See also:
RecursiveGaussianImageFilter::SetNormalizeAcrossScale
template<typename TInputImage , typename TOutputImage = TInputImage>
void itk::LaplacianRecursiveGaussianImageFilter< TInputImage, TOutputImage >::SetSigma ( RealType  sigma)

Set Sigma value. Sigma is measured in the units of image spacing.
