摘要
本文通过对光流基本约束项和平滑约束项加以改进,提出一种自适应的光流估计算法。这种算法能够较精确进行光流运动估计,减轻Horn方法中全局平滑约束对运动边界的影响,提高估计的峰值信噪比。实验结果表明:这种算法是有效的。
An adaptive method of optical flow estimation is proposed by modifying the smoothness constraint and optical flow constraint.Using this method,accuracy of estimation can be enhanced,the harmful effect on the motion edge by global smoothness constraint in Horn algorithm can be weakened and the PSNR of estimation can be improved.Experimental results show that this method is suitable and effective.
