[Insight-users] Bug in GradientVectorFlowImageFilter

[Ivan Macia]

Hi Luis,

You may probably have guessed it. The reason was that the tests are =
using an
external Laplacian filter with a call to SetLaplacianFilter() and in my =
case
I didn't provide it because im very lazy :)

By the way, is the Bug Tracker thing only for developers or is also for
users? Should I post bugs here?

Later

Ivan
