摘要

本文提出了一种利用改进的Sigmoid窗口进行重叠块运动补偿(OBMC)的新方法。本文提出的MSW-OBMC方法使用可变加权函数生成窗口，以最大限度地减少所考虑的块边缘上的块伪影。该方法适用于任何分块运动补偿方案。通过与其他相关方法的对比，该方法在降低预测误差能量或块伪影方面表现出更好的性能。

Overlapped Block Motion Compensation Using Modified Sigmoid Window

In this paper, we present a new method to perform overlapped block motion compensation (OBMC) using the modified Sigmoid window (MSW). The proposed MSW-OBMC method uses a variable weighting function to generate a window in order to maximally reduce the blocky artifacts on the edges of the block under consideration. It can be applied in any block partitioned motion compensation scheme. Benchmarked with other relevant methods, the proposed method shows better performance in reducing prediction error energy or blocky artifacts.
