[Insight-users] information back from threads for writing multi-threaded filters

[Bradley Lowekamp]

Hello Arindam,

The itkStatisticsImageFilter would be a good filter to examine. In uses arrays of the size of the number of threads. Allocating them in BeforeThreadedGenerateData, and then gathering the computation in the AfterThreadedGenerateData methods.
