[Insight-users] Multi-threading for K-Means classification

[Luis Ibanez]

Hi Anu,

I'm not aware of a multi-threaded version of this filter.


1) What computation time are you observing ?


2) Are you compiling your project in "Release" mode ?
    The compilation mode "Debug" versus "Release"
    can easily make a 10x difference in computation time
    for some ITK filters.



   Regards,


          Luis
