Abstract:
1. A computer implemented method for enabling computer recognition of a particular person in images, comprising the steps of: analyzing one or more facial images of a person using a facial recognition model associated with the person to identify the person and to determine changes in facial appearance of the person; calculating a subject recognition confidence value for the person responsive to the facial recognition model and the determined changes in facial appearance present in the one or more facial images, wherein the subject recognition confidence value is calculated from similarity score distributions, the similarity score distributions being probability distributions indicative of the probability of matching instances of the same person and the probability of matching instances of different persons; comparing the calculated subject recognition confidence value for the person to prior subject recognition confidence values calculated using prior images of the person to identify changes in the subject recognition confidence values; analyzing the identified changes in the subject recognition confidence values of determine whether a new facial recognition model for the person should be generated based on the determined changes in the facial appearance of the person; generating the new facial recognition model from current of subsequent images of the person is it is so determined by the step of analyzing the identified changes; and using the new facial recognition model for subsequent person recognition tasks.
