Detailed Description

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

This filter sharpens an image using a Laplacian. LaplacianSharpening highlights regions of rapid intensity change and therefore highlights or enhances the edges. The result is an image that appears more in focus.

The LaplacianSharpening 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.

virtual::itk::LightObject::Pointer itk::LaplacianSharpeningImageFilter< 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::LaplacianSharpeningImageFilter< TInputImage, TOutputImage >::GenerateData ( )

protectedvirtual

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::LaplacianSharpeningImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion ( ) throw ( InvalidRequestedRegionError )

virtual

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

void itk::LaplacianSharpeningImageFilter< 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.

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.

Enable/Disable using the image spacing information in calculations. Use this option if you want derivatives in physical space. Default is UseImageSpacingOn.
