testlab's profile - activity

So I got the 2.4.11 OpenCV library for Android. I am trying to use the org.opencv.contric.FaceRecognizer.java But, I do not understand how do I initiate an instance of that class since this is the constructor's header:

 protected FaceRecognizer(long add)

and there is no documentation that says what should be sent as "add". I'll thank you very much if you will be able to help me. (PS: I can't use the Android API for face recognition, I have to use openCV).
