  • Publication number: 20230368575
    Abstract: The use of multimodal face attributes in facial recognition systems is described. In addition, use of one or more auxiliary attributes, such as a temporal attribute, can be used in combination with visual information to improve the face identification performance of a facial recognition system. In some examples, the use of multimodal face attributes in facial recognition systems can be combined with the use of one or more auxiliary attributes, such as a temporal attribute. Each of these techniques can improve the verification performance of the facial recognition system.

  • Patent number: 11763551
    Abstract: An authentication engine, residing at one or more computing machines, receives, from a vision device comprising one or more cameras, a probe image. The authentication engine generates, using a trained facial classification neural engine, one or more first labels for a person depicted in the probe image and a probability for at least one of the one or more first labels. The authentication engine determines that the probability is within a predefined low accuracy range. The authentication engine generates, using a supporting engine, a second label for the person depicted in the probe image. The supporting engine operates independently of the trained facial classification neural engine. The authentication engine further trains the facial classification neural engine based on the second label.
