.... objects is that of physics based deformable models, introduced in [11] It has been widely used for tracking of 3D objects and for non rigid motion modeling [4] 5] 17] Coupled with the Kalman filtering approach, this method has been extended to handle complex motions of non rigid objects [15] [16]. However the physics based methods require knowledge of certain physical properties of the bodies in question, which are not always available. Some approaches ( 1] 6] 7] estimate the model properties using a set of cue points manually chosen at initialization stage. In reallife applications ....

....length shortly, demonstrates the ability of such trackers to succeed. The active contour literature is vast, so no attempt will be made to review it comprehensively. The field originated with the snake formulation of Kass, Witkin, and Terzopoulos [8] and many papers in a similar vein followed [1, 17, 19]. The recent trend has been towards geometric curve evolution [3, 9, 10, 4] and this paper will follow in that tradition. Many of these recent papers have focused on the novel level set approach to implementing geometric curve flows [14] which allows for a stable numerical scheme, as well as for ....

....then we draw our conclusions in Section 7. 2 Background on Snakes In this section, we briefly review the energy based optimization approach to deformable contours as discussed in [19, 44, 10, 6] For complete details, we refer the interested reader to the collection of papers in [6] especially [43]. Let C(p) x(p) y(p) be a closed contour in R where 0 p 1. Note that the superscript T denotes transpose. We now define an energy functional on the set of such contours ( snakes ) E(C) Following standard practice, we take E(C) to be of the form E(C) E int (C) P(C) where E ....
....oe I(x; y)k; for a suitably chosen constant c, in which case the snake will be attracted to intensity edges. Here G oe denotes a Gaussian smoothing filter of standard deviation oe. One also typically considers dynamic time varying models in which C(p) becomes a function of time as well; see [43]. In this case, one defines a kinetic energy and the corresponding Lagrangian (the difference between the kinetic energy and the energy E defined above) Applying the principle of least action, one derives the corresponding Lagrange equation which one tries to solve numerically employing various ....

....[2] the contour is approximated by B splines. The methods first fit a B spline curve to intensity edges and then use a Kalman filter or a Monte Carlo filter to track the B spline coefficients. In [3] Fourier coefficients are used as parameters of the contour. In several other tracking algorithms [4], 5] the contour detection is performed by minimizing some energy function, using extensions from the snake model of Kass et al. 6] In the Kalman snakes, the Euler Lagrange equation is the basis for the construction of the predicted next instance of the contour. The implementation of the ....
