Hi, that module is part of opencv3.
There shouldn't be any problem using that openCv module along with OF, as long as you have opencv3.
The current OF release (0.9.8) comes with opencv2.4.9 precompiled.
The current github master comes with opencv3.1 but you'll need to run some scripts for making the whole thing to work, which depend on your OS. Which I do not recommend if you're not used to.
I think that could download apothecary which is this tool that OF uses to build it's libraries. Place it in your openFrameworksFolder/scripts/ and run it according to its readme. This should build opencv3.
Let me know how it goes.
