Optical flow: A curve evolution approach

A novel approach for the computation of optical how based on an L(1) type minimization is presented, It is shown that the approach has inherent advantages since it does not smooth the flow-velocity across the edges and hence preserves edge information, A numerical approach based on computation of evolving curves is proposed for computing the optical flow field. Computations are carried out on a number of real image sequences in order to illustrate the theory as well as the numerical approach.
