[Insight-developers] SimpleRegistrationMehod const correctness

[Bradley Lowekamp]

There are other difference between the simple method and the standard image registration method.

You do not have the fixed and moving images as input into the process object.


template< typename TFixedImage, typename TMovingImage >
void
ImageRegistrationMethod< TFixedImage, TMovingImage >
::SetFixedImage(const FixedImageType *fixedImage)
{
  itkDebugMacro("setting Fixed Image to " << fixedImage);

  if ( this->m_FixedImage.GetPointer() != fixedImage )
    {
    this->m_FixedImage = fixedImage;

    // Process object is not const-correct so the const_cast is required here
    this->ProcessObject::SetNthInput( 0,
                                      const_cast< FixedImageType * >( fixedImage ) );

    this->Modified();
    }
}

I am not sure what the implications are of not having the images a inputs into the simple method.
