Abstract
Multiple reference frame motion estimation (MRFME) is one of the main features of recent video coding standards such as H.264/AVC and high efficiency video coding. This paper presents a fast search strategy for avoiding redundant computations during MRFME. The proposed method reduces the number of pixels to be examined using the precalculated rate-distortion costs of previously searched frames. Experimental results show that the proposed method reduces the complexity of the motion estimation (ME) process by up to 81.43 %.
