Abstract In this paper, an improved algorithm combining optical flow field with labeling field is presented for estimating the two-dimension motion. Based on the basic constraint and the global smooth constraint, a labeling field is introduced, by which Horn-Schunck algorithm is modified. This method not only fastens the convergence of the algorithm, but also improves the accuracy and weakens the effect of the occluding boundary on the motion estimation. The experimental results show that it is a suitable method.
