Detailed Description

template<class TInputImage, class TOutputImage>
class itk::LaplacianImageFilter< TInputImage, TOutputImage >

This filter computes the Laplacian of a scalar-valued image. The Laplacian is an isotropic measure of the 2nd spatial derivative of an image. The Laplacian of an image highlights regions of rapid intensity change and is therefore often used for edge detection. Often, the Laplacian is applied to an image that has first been smoothed with a Gaussian filter in order to reduce its sensitivity to noise.

The Laplacian at each pixel location is computed by convolution with the itk::LaplacianOperator.
Inputs and Outputs
The input to this filter is a scalar-valued itk::Image of arbitrary dimension. The output is a scalar-valued itk::Image.
Warning:
The pixel type of the input and output images must be of real type (float or double). ConceptChecking is used here to enforce the input pixel type. You will get a compilation error if the pixel type of the input and output images is not float or double.

Member Function Documentation

template<class TInputImage , class TOutputImage >
virtual::itk::LightObject::Pointer itk::LaplacianImageFilter< 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<class TInputImage , class TOutputImage >
void itk::LaplacianImageFilter< TInputImage, TOutputImage >::GenerateData ( ) [protected, virtual]

Standard pipeline method. While this class does not implement a ThreadedGenerateData(), its GenerateData() delegates all calculations to an NeighborhoodOperatorImageFilter. Since the NeighborhoodOperatorImageFilter is multithreaded, this filter is multithreaded by default.

Reimplemented from itk::ImageSource< TOutputImage >.

template<class TInputImage , class TOutputImage >
virtual void itk::LaplacianImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( ) throw ( InvalidRequestedRegionError ) [virtual]

LaplacianImageFilter needs a larger input requested region than the output requested region (larger in the direction of the derivative). As such, LaplacianImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

ImageToImageFilter::GenerateInputRequestedRegion()

template<class TInputImage , class TOutputImage >

template<class TInputImage , class TOutputImage >
virtual bool itk::LaplacianImageFilter< TInputImage, TOutputImage >::GetUseImageSpacing ( ) const [virtual]

Set/Get whether or not the filter will use the spacing of the input image in its calculations

template<class TInputImage , class TOutputImage >
static Pointer itk::LaplacianImageFilter< TInputImage, TOutputImage >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<class TInputImage , class TOutputImage >
void itk::LaplacianImageFilter< 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.

void itk::LaplacianImageFilter< 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.
