DescriptionThe gallery exhibition had a real-time display which used the OpenFace facial recognition system created by Brandon Amos, Bartosz Ludwiczuk, and Mahadev Satyanarayanan at Carnegie Mellon University. It is analyzing the stream of information coming into the computer from the camera, looking for faces. When a face is found, a rectangle is placed around it on the screen. When more than one person is identified, it differentiates between them with separate colors. The system also represents the faces as points on a sphere, as shown in the upper left corner. Similar faces (like identical twins) will be represented nearer to one another on the sphere than faces that are more visually different. When this algorithm is used in practice, the computer uses 128 mathematical dimensions to represent the faces instead of just the three physical dimensions represented by the sphere. This technique, like many other facial recognition techniques, can also associate names with faces, a practice used by Facebook when it auto-tags faces in photographs.
