Abstract

Warping-based motion estimation has been proposed in the literature to achieve higher video coding efficiency compared to conventional block-based motion estimation. This paper investigates the performance of warping-based methods at very low bit rates typical of mobile video communication applications. Simulation results show that despite their improvements over block-based methods, the use of warping-based methods in such applications may not be justifiable due to the huge increase in computational complexity. In fact, it is shown that similar, if not better, improvements can be obtained, at a fraction of the complexity, by simply augmenting basic block-based methods with techniques like subpel accuracy and overlapped motion compensation.
基于翘曲的运动估计性能研究
与传统的基于块的运动估计相比,文献中提出了基于翘曲的运动估计,以实现更高的视频编码效率。本文研究了基于翘曲的方法在极低比特率下移动视频通信应用的性能。仿真结果表明,尽管基于块的方法有所改进,但由于计算复杂性的巨大增加,在此类应用中使用基于翘曲的方法可能是不合理的。事实上,它表明,如果不是更好,类似的改进可以获得,在复杂性的一小部分,通过简单地增加基本的基于块的方法与技术,如子像素精度和重叠运动补偿。
