Abstract :
An iterative multiresolution method based on finite elements for estimating the optical flow is presented and applied to video coding. The computed motion field is smooth and can be represented by a small number of finite-element coefficients. Preliminary simulation results are encouraging, as good quality estimates are obtained for the Salesman sequence
