I am sort of new to this, so excuse me if I make any obvious mistakes. I recently found that my tracking code does not work very well on older computers. So naturally I looked to parallelization. Unfortunately, I use prebuilt libraries, and thus am unable to use tbb. (cake was giving me issues) however, I read that recently, in 2.4.3, concurrency was added into the opencv library. my question is, how the heck do I use it?
