Get OpenCV working with Unity

Hi,
I’m a student and as project, I’d like to do some work with Unity and OpenCV.
I’ve been doing some research on the forum and I saw that some of you succeed to use OpenCV with Unity.
My question is quite simple : How do you do that ? am a bit stuck and I didn’t find anything which could explain me the “how to”.
I hope you’ll be able to help me, I’d be very grateful. Am working on a Mac with snow leopard, and I’m using a pro version of Unity, if that could help you to guide me.
Thanks.

Hi! I have the same problem and no pro version of Unity. Is it possible to get opencv working with non-pro version of Unity?

Hey guys! Iam a student. I have the same problem . But I have just a unity(free version) ! Is it possible to import 3d parties Libraries(particularly OPENCV) and how ? If not , is it possible to do it with unityPRO ? and How? The answer is very important for me.
