Abstract
Multiple reference frame motion estimation (MRF-ME) is an important tool in H.264 to improve coding efficiency. However, it penalizes the encoder in computational complexity. When the number of reference frames increases, therequired computation expands proportionally. Therefore, various motion vector composition algorithms have been proposed to reduce the computational complexity of the encoder. However, it is found that they only perform well in a limited range of reference frames. In this paper, a new composition algorithm is proposed to compose a resultant motion vector from a set of candidate motion vectors. The proposed algorithm is especially suited for temporally remote reference frames in MRF-ME. Compared with existing algorithms, experimental results show that the new algorithm can deliver a remarkable improvement on the rate-distortion performance.
