摘要:

融合对于双流网络至关重要。在本文中,我们提出了一种新的时间融合(TF)模块,融合两个流关节的信息来预测人体运动,包括一个时间级联和一个强化轨迹时空(TST)块,专门设计来保持预测的时间一致性。特别地,时间级联保持来自两个流的初步预测的时间一致性。同时,TST块改善了时空特征耦合。然而,TF模块可以增加第一预测姿态和给定姿态之间以及每个预测姿态之间的时间连续性。该融合基于由动态速度流(V-Stream)和静态位置流(P-Stream)组成的双流网络,因为我们发现关节的速度信息改善了短期预测,而关节的位置信息更好地用于长期预测,并且它们在运动预测中是互补的。最后,我们的方法在三个基准数据集上取得了令人印象深刻的结果,包括H3.6M,CMU-Mocap和3DPW的短期和长期预测,证实了其有效性和效率。

英文摘要:

Fusion is critical for a two-stream network. In this paper, we propose a novel temporal fusion (TF) module to fuse the two-stream joints' information to predict human motion, including a temporal concatenation and a reinforcement trajectory spatial-temporal (TST) block, specifically designed to keep prediction temporal consistency. In particular, the temporal concatenation keeps the temporal consistency of preliminary predictions from two streams. Meanwhile, the TST block improves the spatial-temporal feature coupling. However, the TF module can increase the temporal continuities between the first predicted pose and the given poses and between each predicted pose. The fusion is based on a two-stream network that consists of a dynamic velocity stream (V-Stream) and a static position stream (P-Stream) because we found that the joints' velocity information improves the short-term prediction, while the joints' position information is better at long-term prediction, and they are complementary in motion prediction. Finally, our approach achieves impressive results on three benchmark datasets, including H3.6M, CMU-Mocap, and 3DPW in both short-term and long-term predictions, confirming its effectiveness and efficiency.
