[Insight-users] Applying an ImageFunction to every pixel in an image

[David Doria]

I am trying to evaluate GaussianBlurImageFunction at every pixel in an
image. I tried to use UnaryFunctorImageFilter like this:

http://www.itk.org/Wiki/ITK/Examples/Functions/GaussianBlurImageFunctionFilter

but it complains that there is no != operator defined.

Is there a different filter that will apply an ImageFilter to the entire
input image? Or how is this typically done?

Thanks,

David
