  • Multiple-tiered facial recognition
    Patent number: 10733279
    Abstract: A method includes receiving probe image data associated with a biometric authentication request on a mobile device. A first classifier is employed to generate a first probability metric of the probe image data being associated with the authorized user. The biometric authentication request is approved responsive to the first probability metric being greater than a first threshold. The biometric authentication request is denied responsive to the first probability metric being less than a second threshold. Responsive to the probability metric being between the first and second thresholds, a second classifier is employed to generate a second probability metric of the probe image data being associated with the authorized user. The biometric authentication request is approved responsive to the second probability metric being greater than a third threshold.

  • Method for multiclass classification in open-set scenarios and uses thereof
    Patent number: 10133988
    Abstract: The proposed method is used for classification in open-set scenarios, wherein often it is not possible to first obtain the training data for all possible classes that may arise during the testing stage. During the test phase, test samples belonging to one of the classes used in the training phase are classified based on a ratio between similarity scores, as known correct class and test samples belonging to any other class are to be rejected and classified as unknown.
