On a Thursday afternoon in January, Robert Julian-Borchak Williams was in his office at an automotive supply company when he got a call from the Detroit Police Department telling him to come to the station to be arrested. He thought at first that it was a prank.
Wrongfully Accused by an Algorithm
Facial recognition systems are computer-based security systems that are able to automatically detect and identify human faces. These systems depend on a recognition algorithm, such as eigenface or the hidden Markov model. The first step for a facial recognition system is to recognize a human face and extract it fro the rest of the scene. Next, the system measures nodal points on the face, such as the distance between the eyes, the shape of the cheekbones and other distinguishable features.
However, it has recently gained major advances in accuracy and adaptability. Some new facial recognition software has nearly an equal chance of matching two different images or frames of the same face as humans do, demonstrating significant strides in the technology. Social media sites and tech companies have begun to apply facial recognition to their programs and devices.
