First Claim
Patent Images

1. A method performed by one or more computers, the method comprising:

  • obtaining data indicating (i) a facial template for an input facial image, and (ii) reference facial templates for multiple reference facial images;

    computing, by a first facial matcher, a first set of scores representing respective similarities between the input facial image and each of the obtained reference facial templates;

    determining, by the first facial matcher and based on the first set of computed scores, that the input facial image does not match any of the multiple reference facial images;

    in response to determining that the input facial image does not match any of the multiple reference facial images, computing, by a second facial matcher, a second set of scores representing respective similarities between the input facial image and each of the obtained reference facial images,wherein a facial verification technique applied by the second facial matcher has a higher sensitivity than a facial verification technique applied by the first facial matcher;

    determining, by the second facial matcher and based at least on the second set of computed scores, that the input facial image matches a particular reference facial image from among the multiple reference facial images;

    combining the first set of scores and the second set of scores to compute a match score between the input facial image and the particular reference facial image; and

    providing the match score for output.
