A PDE model for computing the optical flow
Luis Álvarez, Julio Esclarín Monreal, Martin Lefébure, Javier Sánchez · 1999
In this paper we present a new model for optical ow calculation using a variational formulation which preserves discontinuities of the ow much better than classical methods We study the EulerLagrange 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 ow constraint it can recover large displacement in the scene We avoid convergence to irrelevant local minima by embedding our method into a linear scalespace framework and using a focusing strategy from coarse to ne scales
