摘要: 研究经典的单向运动估计算法,提出一种基于补偿融合的帧频提升方法。通过融合前后向运动估计的补偿帧减少空洞数量,并采用规则块二次估计算法填补空洞。在匹配准则中加入运动矢量相关性因子和边缘匹配误差,从而提高运动估计的准确性。实验结果表明,该方法计算简单,能够取得较好的插帧效果。

Abstract: This paper researches one-way motion estimation algorithm, and presents a motion compensated Frame Rate Up-conversion(FRUC) method. It merges compensating frames of forward and backward motion estimation and fills up holes of the merging frame. The matching criterion of motion estimation includes correlation factor of motion vector and edge matching error to get more accurate motion vectors. It adopts an easy method to estimate covered/uncovered area using two frames to solve the occlusion problem. A re-estimating method is adopted to fill up the holes existing in merging frame. Experimental results confirm that the proposed method is easy to compute and has a better frame interpolation performance.
