摘要:

在本文中,我们提出了融合-GCN,一种使用图卷积网络(GCN)的多模式动作识别方法。基于GCN的动作识别方法最近为基于GCN的动作识别提供了最先进的性能。使用Fusion-GCN,我们建议将各种传感器数据模式集成到一个图中,该图使用GCN模型进行训练,用于多模式动作识别。附加的传感器测量被合并到图形表示中,或者在通道维度(引入附加节点属性)上或者在空间维度(引入新节点)上。Fusion-GCN在两个公共可用数据集(UTD-MHAD和MMACT数据集)上进行了评估,并展示了RGB序列、惯性测量和骨架序列的灵活融合。我们的方法在UTD-MHAD数据集上获得了可比的结果,并通过融合骨骼估计和加速度计测量,将大规模MMACT数据集的基线提高了高达12.37%(F1-Measure)的显著幅度。

英文摘要:

In this paper, we present Fusion-GCN, an approach for multimodal action recognition using Graph Convolutional Networks (GCNs). Action recognition methods based around GCNs recently yielded state-of-the-art performance for skeleton-based action recognition. With Fusion-GCN, we propose to integrate various sensor data modalities into a graph that is trained using a GCN model for multi-modal action recognition. Additional sensor measurements are incorporated into the graph representation, either on a channel dimension (introducing additional node attributes) or spatial dimension (introducing new nodes). Fusion-GCN was evaluated on two public available datasets, the UTD-MHAD- and MMACT datasets, and demonstrates flexible fusion of RGB sequences, inertial measurements and skeleton sequences. Our approach gets comparable results on the UTD-MHAD dataset and improves the baseline on the large-scale MMACT dataset by a significant margin of up to 12.37% (F1-Measure) with the fusion of skeleton estimates and accelerometer measurements.
