摘要
本文在基本约束方程和平滑性约束条件下，提出了一种改进的瞬时位置速度估计方法．这种方法不仅能够克服Ｈｏｒｎ方法在计算临近边界的非运动点速度“漂移”问题，而且能加快算法的收敛速度，提高预测的准确性．通过对２Ｄ运动图像光流场计算、恢复和峰值信噪比（ＰＳＮＲ）的实验研究表明：这一新方法是有效的。
In this paper,an improved method of optical flow (OF) estimation is proposed under the condition of the basic constraint equation and the smooth constraint. The method not only can resolve the problem of velocity transmission at the points near boundary ,it also can speed up the convergence of the algorithm and enhance the accuracy of estimation. estimation the experiments of 2D motion field, it is shown that the proposed method is suitable for OF computation.
