[Insight-users] [ITK Community] ScalarChanAndVeseDenseLevelSetImageFilter

[Luis Ibanez]

Hi Inspirationv,


The line

    levelSetFilter->SetUseImageSpacing(0.28125 )


Should have an argument (0 or 1) or (true or false),

since it is expecting a boolean:


    levelSetFilter->SetUseImageSpacing( boolean )



   Hope this helps,


     Luis
