[Insight-users] MPI Vector Gradient Anisotropic Diffusion Image Filter

[Kevin H. Hobbs]

The attached allow for 20 iterations of the full Visible Woman Head data
set in 25 minutes on 8 nodes with 2 Intel Xeon X5550 CPUs and 12 GB of
RAM each connected with Gigabit ethernet.

There's still some clean-up to be done on the final writing, I get :

WARNING: In /home/kevin/kitware/ITK/Code/IO/itkMetaImageIO.cxx, line 1663
MetaImageIO (0x268e2a0): Pixel types does not match file, but component
type and number of components do.

for each piece.

The command was :

time mpirun \
  -hostfile ~/mpi_hostsfile \
  ./MPIVectorGradientAnisotropicDiffusionImageFilter \
  VisibleWomanHead/RawRGB/VisibleWomanHeadFull.mhd \
  VisibleWomanHeadFull_Smooth.mhd \
  1.0 20 0.03

Could this warning be related to the input file having unsigned char
component type while I'm using :

typedef itk::RGBPixel < float >                  RGBPixelType;
typedef itk::Image< RGBPixelType, Dimension >    RGBImageType;

throughout the program?
