Jeff;
As DD pointed, you can look at www.biometricsview.com for information on face recognition. In the
FAQ section there is information on integrating the Face Recognition toolkit with other webcam toolkits for LabVIEW. Check it here:

I know that INVENTeering also developed a motion detection routine which you can download from their website. However, it seems that at this time they are renovating their website www.inventeering.com, so check out a little bit later.
