Claim 6:
7. A method, comprising:
receiving an uncovered face image of a subject;
generating a first fixed-size representation (FXR) based on the uncovered face image;
generating a covered face image of the subject based on the uncovered face image by at least:
detecting, via a face detection algorithm, a face, a nose, and a mouth of the subject within the uncovered face image;
generating a cropped face image by cropping the face from the uncovered face image according to a normalized coordinate set;
aligning, via an image warping technique, the cropped face image according to the normalized coordinate set; and
fitting a 3-D virtual face covering to the cropped face image such that the 3-D virtual face covering covers the nose and the mouth of the subject;

generating a second FXR based on the covered face image; and
creating a record of the first FXR and the second FXR in association with the subject.
