Issue Date: | 1999 | Abstract: | In this paper we present a new model for optical flow calculation using a variational formulation which preserves discontinuities of the flow much better than classical methods. We study the Euler-Lagrange equations asociated to the variational problem. In the case of quadratic energy, we show the existence and uniqueness of the corresponding evolution problem. Since our method avoid linearization in the optical flow constraint, it can recover large displacement in the scene. We avoid convergence to irrelevant local minima by embedding our method into a linear scale-space framework and using a focusing strategy from coarse to fine scales. | URI: | http://hdl.handle.net/10553/11772 | Source: | Proceedings of CEDYA XVI. -- Las Palmas de Gran Canaria: Universidad de Las Palmas de Gran Canaria, September 1.999. -- pp. 1349-1356 | Rights: | by-nc-nd |
