How to detect face recognition using Kinect?

Question

I'm trying to develop a software where can detect face recognition using Kinect.

Until now, I just know I can use OpenCV to do this feature. I just want that the camera can save the face and recognize him later.

I've just use KinectSDK, so I need some help or orientation to implement the feature.

I think that you can do that by using depth stream. Each pixel has his own depth (distance from the KInect). Each face has a uniq patter. So you can save a pixel depth pattern and compare it.
