1. A facial biometric access method for controlling access for at least one tracked subject, each tracked subject having an associated unique tracking identifier, comprising:
acquiring or receiving a series of two-dimensional images of a facial area of a first tracked subject in a field of view of an image capture device, wherein the first tracked subject relates to a first person being in front of a queue and is assigned a first unique tracking identifier;
providing trajectory data of the facial areas of the first tracked subject from a plurality of position data, each associated with one image of the series of two-dimensional images;
determining if there is a discontinuity in the trajectory by analyzing the trajectory data, and if a discontinuity is detected, reacquiring a new series of two-dimensional images of a facial area of a second tracked subject in the field of view of the image capture device, wherein the second tracked subject relates to a second person being now in front of the queue, the first and second person being the same or different, and assigning a second unique tracking identifier to the second tracked subject; and
determining whether access should be allowed based on the second unique tracking identifier and a match between a reference database of subjects and at least one image from the new series of two-dimensional images if discontinuity is detected, or based on the first unique tracking identifier and a match between the reference database of subjects and at least one image from the series of two-dimensional images if discontinuity is not detected.
