[Insight-users] Multithreading

[Dženan Zukić]

Here is an example when you implement your own multi-threaded
filter<http://www.itk.org/Wiki/ITK/Examples/Developer/OilPaintingImageFilter>.
More examples <http://www.itk.org/Wiki/ITK/Examples>.

Multithreaded filters are called the usual way: filter->update(), but they
make use of all the processor cores (unlike the single-threaded ones). On
top of that you can make your own application parallel (for example, have
one thread read images from disk while the main thread handles user
interaction).
