[Insight-users] Stream/Thread Pipeline Details

[Brady McCary]

Insight-users,

In the ITK stream/thread pipeline for a finite difference image
filter, an image can be broken into regions and streamed/threaded. In
this case, which of the following happens between iterations:

1. All threads execute InitializeIteration() individually (potentially
several executions of InitializeIteration()).

2. All threads join and InitializeIteration() is executed once (exactly once).
