Hi everybody.
i'm new ITK user.I take the exixtance of the toolkit two weeks ago.hav
alredy dowload and install the ITK, VTK,InsightApplications via visual
studio 9 and all the process hav been buitt succefully. Now i want to run
one of the insightapplications in order see resuts,but i don't know how to
pass the argument witch the code require in visual studio. If we consider
the example bellow .As it's indicate in the comment , the code require seed
points and the original image as inputs : My question is how and where and
what do i need to put this arguments( seed and original image) in the code
in order to display the result (I use Visual studio 9) ??? any explanation
of this code is welcome.
Please I need help in emergency . Thanks and sorry for the mistakes (cause
i'm french).
