[Insight-users] Compilation warnigns from VectorCurvatureAnisotropicDiffusionImageFilter

[Luis Ibanez]

Hi Uwe,

It seems that you are instantiating this filter for an image of pixel 
type char.

You may want to cast your image to pixel type float, and instantiate this
filter over an image of pixel type = float.

Please let us know if you still find any problems,


   Thanks,


        Luis
