[Insight-users] How to use the itkSubtractImagFilter.h

[Luis Ibanez]

Hi Anders,

Please use

    filter->SetInput1(  image1 );
    filter->SetInput2(  image2 );
    filter->Update();


The itk::SubtractImageFilter
http://www . itk . org/Insight/Doxygen/html/classitk_1_1SubtractImageFilter . html

derives from the BinaryFunctorImageFilter
http://www . itk . org/Insight/Doxygen/html/classitk_1_1BinaryFunctorImageFilter . html

which is the abstraction of all the pixel-wise filters
requiring two inputs.


Regards,


   Luis
