A method ( 100 ) of tracking facial features in a video sequence is disclosed. The method receives ( 110 ) as input facial features for tracking in a first frame of the video sequence. The video sequence is also segmented ( 120 ) using spatiotemporal segmentation to provide a sequence of associated two-dimensional segments, with a first segment in the sequence of associated two-dimensional segments including the facial features for tracking. Candidate facial features are then identified ( 140 ) in at least a second two-dimensional segment in the sequence of associated segments. Method ( 100 ) then verifies ( 155 ) which of the candidate facial features correspond with the facial features for tracking. Method ( 100 ) also recovers lost facial features by using known geometric relations between facial features.
