Detailed Description

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

Applies an averaging filter to an image.

Computes an image where a given pixel is the mean value of the the pixels in a neighborhood about the corresponding input pixel.

A mean filter is one of the family of linear filters.

Member Function Documentation

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

MeanImageFilter needs a larger input requested region than the output requested region. As such, MeanImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model. See also: ImageToImageFilter::GenerateInputRequestedRegion() Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual const char* itk::MeanImageFilter< TInputImage, TOutputImage >::GetClassName (    )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> virtual const InputSizeType& itk::MeanImageFilter< TInputImage, TOutputImage >::GetRadius (    )  [virtual]

Get the radius of the neighborhood used to compute the mean

template<class TInputImage, class TOutputImage> itk::MeanImageFilter< TInputImage, TOutputImage >::itkStaticConstMacro (  OutputImageDimension   , unsigned    int, TOutputImage::ImageDimension    )

Extract dimension from input and output image. Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

template<class TInputImage, class TOutputImage> itk::MeanImageFilter< TInputImage, TOutputImage >::itkStaticConstMacro (  InputImageDimension   , unsigned    int, TInputImage::ImageDimension    )

Extract dimension from input and output image. Reimplemented from itk::ImageToImageFilter< TInputImage, TOutputImage >.

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

Method for creation through the object factory. Reimplemented from itk::Object.

template<class TInputImage, class TOutputImage> void itk::MeanImageFilter< 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<class TInputImage, class TOutputImage> virtual void itk::MeanImageFilter< TInputImage, TOutputImage >::SetRadius (  InputSizeType    _arg )  [virtual]

Set the radius of the neighborhood used to compute the mean.

template<class TInputImage, class TOutputImage> void itk::MeanImageFilter< TInputImage, TOutputImage >::ThreadedGenerateData (  const OutputImageRegionType &    outputRegionForThread, int    threadId )  [protected, virtual]

MeanImageFilter can be implemented as a multithreaded filter. Therefore, this implementation provides a ThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling ThreadedGenerateData(). ThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread" See also: ImageToImageFilter::ThreadedGenerateData(), ImageToImageFilter::GenerateData() Reimplemented from itk::ImageSource< TOutputImage >.
