Tracking Faces in Places

Faces in Places ist eine alte Internet-Meme, basierend auf der gleichnamigen Website, die wiederum auf dem alten psychologischen Prinzip Pareidolia fusst: Gesichter in Gegenständen sehen. Kann man machen. Viel spannender finde ich allerdings die Idee von Greg Borenstein, der eine Facetracking-Software über sämtliche Bilder einer ähnlichen Flickr-Gruppe laufen lies um zu sehen, ob die in den Fotos ebenfalls Gesichter erkennt.

Facial recognition techniques give computers their own flavor of pareidolia. In addition to responding to actual human faces, facial recognition systems, just like the human vision system, sometimes produce false positives, latching onto some set of features in the image as matching their model of a face. Rather than the millions of years of evolution that shapes human vision, their pareidolia is based on the details of their algorithms and the vicissitudes of the training data they’ve been exposed to.

Their pareidolia is different from ours. Different things trigger it.

I decided to run all of the images from the Hello Little Fella Flickr group through FaceTracker and record the result. These images induce pareidolia in us, but would they do the same to the machine?
