Its even got little green boxes and everything. <object CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" width="320" height="260" CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab"> <param name="src" value="sample.mov"> <param name="qtsrc" value="http://www.thepresentgroup.com/documents/sony_cam.mpg"> <param name="loop" value="false"> <param name="controller" value="true"> <embed src="sample.mov" qtsrc="http://www.thepresentgroup.com/documents/sony_cam.mpg" width="320" height="260" autoplay="false" loop="false" controller="true" pluginspage="http://www.apple.com/quicktime/"></embed> </object> Check out this new commercial for a sony camera with facial recognition technology that finds the faces in a picture “because,” as a voice-over says, “the face makes the photo.” Its even got little green boxes and everything.

And actually, for three of the eight photos Ben & I stretched our definition of what counts as a match to a non-face (we included a match to a stencil of a human face, a match to a photo within the photo, and a match to a kitten). Also, keep in mind that there is an issue of scale here--the algorithm has so far evaluated 2,250,000+ photos--so even if an error is very unlikely, it will happen. Finally, as explained by TPG, I did adjust the settings on the algorithm. When using facial-recognition software you have to balance the tendency false false-positives (i.e., not identifying a face that is there and/or not recognizing a match) vs. false positives (i.e., identifying a non-existent face and/or match). I turned the "knob" to err on the side of false positives.
