[Insight-users] LevelSetEquationTermContainer->SetInput() ?

[Arnaud Gelas]

Hi Vaaksiainen,

The SetInput method of LevelSetEquationTermContainer is used and needed 
only in the case where no input images are provided to each term.
It provides the input of the container to each element...

In your case, each term provided one input image, so there is no need to 
provide an input image to the container. If you provide one in such a 
case, it would not get used anyway...

Best,
Arnaud
