Detailed Description

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

Applies a median filter to an image.

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

A median filter is one of the family of nonlinear filters. It is used to smooth an image without being biased by outliers or shot noise.

This filter requires that the input pixel type provides an operator<() (LessThan Comparable).

Member Function Documentation

template<class TInputImage , class TOutputImage >
virtual::itk::LightObject::Pointer itk::MedianImageFilter< 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::BoxImageFilter< TInputImage, TOutputImage >.

virtual const char* itk::MedianImageFilter< TInputImage, TOutputImage >::GetNameOfClass ( ) const [virtual]

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

Method for creation through the object factory.

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

template<class TInputImage , class TOutputImage >
void itk::MedianImageFilter< 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::BoxImageFilter< TInputImage, TOutputImage >.

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

MedianImageFilter 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"
