[Insight-users] Speeding up the evaluation of the itk::Gaussian?

[Luis Ibanez]

Hi Mote,

You need to build in the *SAME* configuration mode,
both ITK *and* your application.

Please do the following:

   1) Load the ITK solution file into Visual Studio.
   2) Select Configuration = Release
   3) Build ITK
       (verify that you get an ITKCommon.lib file
       in the directory:   ITKBINARY/bin/Release)
   4) Load your project solution into Visual Studio
   5) Select Configuration = Release
   6) Build your application


   Regards,


           Luis
