Optical flow: a curve evolution approach
A. Kumar, Allen Tannenbaum, G.J. Balas · IEEE Transactions on Image Processing · 1996
A novel approach for the computation of optical flow 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.
