Detailed Description

template<typename TInputImage, typename 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.

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.

void itk::MeanImageFilter< TInputImage, TOutputImage >::ThreadedGenerateData ( const OutputImageRegionType &  outputRegionForThread, ThreadIdType  threadId  )

overrideprotectedvirtual

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"
