Zusammenfassung:An apparatus and method for tracking a head of a subject in a series of images includes receiving a series of images of at least a portion of a subject's head; tracking a position of the subject's head in the series of images based on positions of a first plurality of primary features of the subject's head; determining a first confidence level of the position of the subject's head based on the positions of the first plurality of primary features; monitoring a position of a secondary feature; and upon determining that the first confidence level is below a defined threshold, tracking the position of the subject's head based on the position of the secondary feature rather than the positions of the primary features.
