摘要
提出了一种改进的三维递归搜索(3-Dimension Recursive Search,3DRS)帧率上转换算法。相较于3DRS算法,在3个方面提出改进:首先,调整候选运动矢量的选择,充分利用运动失量的空间相关性;其次,增加一次逆序运动估计,加速运动失量收敛;最后,提出一种新的匹配准则以进一步提高运动估计的准确性。实验结果表明,该算法有效提高了运动估计的准确性,所得结果在主客观均取得较好的效果。
A frame rate up-conversion algorithm based on improved 3D Recursive Search （3DRS） is presented. Compared with 3DRS algorithm,im- provements from the following three aspects are proposed： firstly, adjust the selection of motion vector candidates to make full use of motion vector＇ s spatial correlation;then,add a reverse motion estimation to accelerate motion vector＇ s convergence ;finally, a new matching criterion is put forward so as to further improve the accuracy of motion estimation. Experimental results show that the algorithm in this paper effectively improves the accuracy of motion estimation and the results achieve better effects both subjectively and objectively.
