Robust optical flow estimation - Information Intelligence and Systems, 1999. Proceedings. 1999 International Conference on

In this paper a new robust estimator of the optical flow field is shown. Arising from the techniques based on the O.EC. (Optical Flow Constrain), we develop an estimation that takes several measures around a given pixel and discards the erroneous ones, using a voting schema. In this way, velocities that have more accumulated votes are taken as the correct ones. A preliminary comparison with other well known techniques is shown, and clearly our approach performs quite bette6 even in the cases where two o r more movements are present in the analyzed pixels.
