A general search strategy for multiple reference frame motion estimation

Multiple reference frame motion estimation (MRFME) is one of main features of recent video coding standards such as H.264/AVC and HEVC. In this paper, we present a general search strategy for MRFME. The proposed method can accelerate the conventional full search algorithms without any penalty in the rate-distortion (RD) performance. Experimental results show that the proposed method can reduce the motion estimation (ME) time of the conventional algorithms up to 39.48%.
