itk::ImageAlgorithm Class Reference

#include <itkImageAlgorithm.h>

Detailed Description

A container of static functions which can operate on Images with Iterators.

These methods are modeled after the STL algorithms. They may use special optimization techniques to implement enhanced versions of the methods.

Member Function Documentation

template<typename InputImageType , typename OutputImageType >

static void itk::ImageAlgorithm::Copy ( const InputImageType *  inImage, OutputImageType *  outImage, const typename InputImageType::RegionType &  inRegion, const typename OutputImageType::RegionType &  outRegion  )

inlinestatic

This generic function copies a region from one image to another. It may perform optimizations on the copy for efficiency.

This method performs the equivalent to the following:

*     itk::ImageRegionConstIterator<TInputImage> it( inImage, inRegion );
*     itk::ImageRegionIterator<TOutputImage> ot( outImage, outRegion );
*
*     while( !it.IsAtEnd() )
*       {
*       ot.Set( static_cast< typename TInputImage::PixelType >( it.Get() ) );
*       ++ot;
*       ++it;
*       }
* 

Note

: It is important not to explicitly pass the template arguments to this method as it may not result in an optimized method being called.

template<typename TType >

static TType* itk::ImageAlgorithm::CopyHelper ( const TType *  first, const TType *  last, TType *  result  )

inlinestaticprivate

Function to dispatch to std::copy or std::transform.

Definition at line 192 of file itkImageAlgorithm.h.

template<typename InputImageType , typename OutputImageType >

static void itk::ImageAlgorithm::DispatchedCopy ( const InputImageType *  inImage, OutputImageType *  outImage, const typename InputImageType::RegionType &  inRegion, const typename OutputImageType::RegionType &  outRegion, TrueType  isSpecialized  )

staticprivate

This is an optimized method which requires the input and output images to be the same, and the pixel being POD (Plain Old Data).

this is the reference image iterator implementation
