Detailed Description

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

A 2D or 3D edge detection using the Sobel operator.

This filter uses the Sobel operator to calculate the image gradient and then finds the magnitude of this gradient vector. The Sobel gradient magnitude (square-root sum of squares) is an indication of edge strength.

Member Function Documentation

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

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