This figure shows lips tracking in a video sequence. The upper row
shows the result of localy deforming the contour. The too high
number of degrees of freedom lead the model to lock on incorrect
edges. The bottom row shows the contour after hybrid
deformations. Constraints made the model more robust and the
retrieved contour is closer to the lips.
