[ITK] [ITK-users] Problems Using GPU Filters

[Andaharoo]

I can't get the images to go from CPU to GPU on GPUMeanImageFilter,
GPUBinaryThresholdImageFilter, and GPUDiscreteGaussianImageFilter. So I
can't start my gpu pipeline with these filters. If I apply something like
GPUGradientAnisotropicImageFilter (which does work) then I can apply the
other filters confirming that it can go GPU to GPU but not CPU to GPU on
those 3 filters. Do these 3 filters not support conversion? 

GPUInputImage::Pointer inPtr =
dynamic_cast<GPUInputImage*>(this->ProcessObject::GetInput(0));
inPtr was null when I debugged GPUMeanImageFilter. This line also doesn't
make sense in terms of using an Image since it would just return null if you
gave it an Image that wasn't allocated as a GPUImage. Unless the cpu image
gets converted to a gpu image elsewhere beforehand?

It seems as though only GPUInPlaceImageFilters work with CPU - GPU
conversion for me? I can't quite understand the GPUInPlaceImageFilters
source yet so I'm not so sure why GPUGradientAnisotropicImageFilter works.
They are, of course, different in terms of how they manage memory.
