摘要: In this paper, a new motion compensation scheme based on dense true motion fields is investigated for video coding. The proposed technique is similar to the block-based decoder-side motion estimation method except that dense motion fields estimated from previously decoded frames are used for frame prediction. This paper demonstrates that even with compression distortions, an iterative dense true motion estimation technique can still produce good quality dense motion fields for video coding or frame-rate up-sampling applications. In particular, we have shown that when the new dense motion field compensation tool is integrated into the B-frame codec of H.264, one can achieve up to 8% overall BD bit-rate savings using standard MPEG test sequences.
