[Insight-users] Initial level set capture

Hi,

The easiest way to do this is to write an itkCommand object that saves the
output of the filter every N iterations.  Then use the AddObserver method
in the filter register this command with the itk::IterationEvent().  See
the file
InsightApplications/ThresholdSegmentationLevelSetFltkGUI/SegmenterConsole.c=
xx
for an example of how to do this (start at line 109).  Be sure to use a
temporary image (one not attached to the filter pipeline) as the input to
the file writer.  Again, see the above referenced file for details (line
798).

Josh.
