Via Urban Honking, a strange experiment in using facial recognition technology to find the face-like forms constantly embedded in our surroundings. What does it all mean?
Pareidolia [is] the natural human inclination to see faces everywhere around us. Matt Jones advocates designing faces into new technology products as a way of making them more approachable, using pareidolia to give products personality and humanize them.
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.
