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.
