I'm trying to work in a project that consist in create an aplication wich have to identify de people that works in a place, so do i don't know how to start, i know that i have to do two steps first the facial detection and then the facial recognition. But there's the problem i can't find the way to capture the face in live. Please help me, and something more i'm working in visual studio and of course open cv

are you trying to survey people at work ? that sounds like a horrible idea

I suspect OpenCV is used for /far/ more morally suspect tasks... you seem to be reading a lot into the OPs question, it might be simply to ID someone who is not on the employee list, some kind of security thing, no?

ah, you're probably right

First step : face detection --> only works with frontal faces

http://docs.opencv.org/doc/tutorials/objdetect/cascade_classifier/cascade_classifier.html#cascade-classifier

Second step : face recognition --> can be done in many ways, but eigenfaces / fisherfaces is used a lot in practice, when trying to perform this

i would like to know what theory uses the open cv, like neuronal nets or pca or pdc something like that

For the detection of faces, please read the Viola&Jones 2009 BMVC paper. For the recognition task, they give the option to use eigenfaces or fisherfaces. From those faces descriptions are stored and then it is a simply codebook matching algorithm as far as I know.

Ok, thank you so much, but i have problems with the compilation, currently i'm working with the opencv 2.4.3 and the visual 2008, let me say you that i don't have problems in the instalation, i have problems in the source code that you show me:
