Abstract :
Classical definitions of the optical flow involve a conservation law, and a spatial smoothing of the velocities based on a norm of its gradient. We propose to use the divergence of the flow instead of using the gradient. So that the optical flow we obtained is the less divergent flow which satisfies the constraint defined by the conservation law. We propose also a model with occlusions, and show results of reconstructions based on the obtained estimation of the flow
