This paper describes a method to t and track surfaces. We suppose that we have already extracted from a 3-D image some data de ned by a set of points. The tting step makes use of a superquadric model and solves an inverse problem for free-form deformations. This is then used for tracking surfaces in a time sequence of 3D images. We present di erent approaches to track surfaces in a sequence of 3D images. From the tracking, we deduce a estimation of motion and visualize a velocity map.
