[Insight-users] ITK versus Opencv

[Bill Lorensen]

Regarding OpenMP...

At the latest ITKv4 developer meeting we agreed to replace the
pthreads implementation in the current itkMultiThreader with an OpenMP
implementation. This will mean that all threaded filters will benefit
from OpenMP. We also agreed to allow developers to use OpenMP
directives in ITK code.

Assuming all goes well with this transition, then OpenMP will be in
the ITKv4 release (Nov 2011). There will be a beta available in
September 2011.

Regarding the speed difference between ITK and Opencv, it would be
nice to have a set of benchmarks that show the difference between the
two toolkits.
