摘要：

We present a method for true-motion estimation assisted by feature point correspondences. First the difference between true-motion estimation and motion estimation for coding applications is explained, and an earlier published efficient true-motion estimation algorithm, called 3DRS, is summarized. Then the convergence property of this algorithm is discussed. We present a method for improving the convergence, by using feature point correspondences and show that a significant quality increase can be obtained for sequences containing high velocities.
