Hi ITK community,
I am currently trying to figure out what is the usual way to visualize the
progress of an evolving front of a level-set filter (or more generally a
FiniteDifferenceImageFilter) in a small application. Is it possible to catch
the update with an observer, get the current state of the evolution
with ->GetOutput(), perform a binary threshold and print the contour to the
display?
Is this the "official way to do it"? Are there other (better?)
possibilities?
Thanks in advance,
Nils
