Regarding OpenMP...<br>
<br>
At the latest ITKv4 developer meeting we agreed to replace the<br>
pthreads implementation in the current itkMultiThreader with an OpenMP<br>
implementation. This will mean that all threaded filters will benefit<br>
from OpenMP. We also agreed to allow developers to use OpenMP<br>
directives in ITK code.<br>
<br>
Assuming all goes well with this transition, then OpenMP will be in<br>
the ITKv4 release (Nov 2011). There will be a beta available in<br>
September 2011.<br>
<br>
Regarding the speed difference between ITK and Opencv, it would be<br>
nice to have a set of benchmarks that show the difference between the<br>
two toolkits.<br>
<br>
