Ross Beveridge's lecture covered all the basics of recognition and delved into a few studies that he and his students performed. He talked about the general flavors of recognition such as verification (Am I who I claim to be), identification (I know you, you are. . . ), and watch list (find the terrorist). He also talked about face matching approaches such as matching the whole image, localized feature based matching, and complex commercial algorithms (he didn't really explain this other to say they exist and they use many different strategies in 1 software program to effectively match faces). From Beveridge's lecture it's apparent that to affectively face match facial features is nontrivial even under the most controlled of situations. Furthermore, minor things such as smiling can easily throw off a given recognition algorithm (he even made reference to a professional system wherein the photographers requested a smile) let alone more major things such as changing backgrounds, skin color etc.
