[Insight-users] from gray image to RGB image

[Luis Ibanez]

Hi Edoardo,


You may also want to use the filter:

       itkScalarToRGBColormapImageFilter.h

That you will find in the directory:

      Insight/Code/Review

and that is described in the following
Insight Journal paper:

"Meeting Andy Warhol Somewhere Over the Rainbow: RGB Colormapping and ITK"

    Regards,


         Luis
