The current paper presents a novel adaptive multiscale scheme to estimate optical flow from image sequences. The scheme models estimation uncertainties which are used to reduce the influence of unreliable intermediate estimates on accuracy. The experimental results show that the proposed method provides more accurate estimates for both small and large motions than a standard multiscale scheme in which an increment is added to an intermediate estimate regardless of estimation certainty.
