基于多帧运动估计的帧率提升算法

摘要

By combining the accuracy of MAP estimation and the high speed of hierarchical block matching, this paper studied the multi-reference frames motion estimation algorithm and proposed a system scheme,which could improve the rate of the frame based on it. Experimental results show that the interpolated frames of the proposed algorithm can perform better than what the current algorithm either in subjective( visual effect) and objective( time complexity ,PSNR) indicators. Besides due to its low computation complexity, this algorithm can be easily realized in hardware.%结合最大后验概率(MAP)估计的准确性和分层块匹配算法的快速性,研究了一种多参考帧运动估计算法,并提出了一种基于多帧运动估计的帧率提升(FRUC)系统方案.实验结果表明,基于该算法的内插帧无论从客观指标(时间复杂度、信噪比PSNR)还是主观质量(视觉效果)均优于现有常用方法,且算法复杂度较低,便于硬件实现.
