[Insight-users] can itkMRFImageFilter discard the intensity information

[Luis Ibanez]

Hi Baoyun,


Please take a look at the example:

   Insight/Examples/Statistics/
       ScalarImageMarkovRandomField1.cxx

You may find it to be a useful guide on how to use the MRF filter.

I'm not sure what you mean by "using the intensity information".
Could you please explain this in more detail ?

A piece of source code will be great....


     Thanks


         Luis
