Description
The documentation says that the default number of threads is equal to the number of processors. I believe that it is actually equal to the number of logical processors. Therefor, if you had 4 cores each with hyperthreading enabled, the default number of threads would be 8.

unfortunately, right now OpenCV uses TBB and (until recently?) this library does not allow to explicitly specify the number of threads to use. Therefore, setNumThreads() right now has no any effect. Let's try to do something with it by the next update

`setNumThreads` should work now for the majority of supported threading frameworks. But documentation really needs update.
