Multi-Scale Spatial Temporal Graph Convolutional Network for Skeleton-Based Action Recognition [PDF]
AAAI Conference on Artificial Intelligence, 2021 Graph convolutional networks have been widely used for skeleton-based action recognition due to their excellent modeling ability of non-Euclidean data. As the graph convolution is a local operation, it can only utilize the short-range joint dependencies ...

Spatial Temporal Graph Convolutional Networks for Skeleton-Based Action Recognition [PDF]
AAAI Conference on Artificial Intelligence, 2018 Dynamics of human body skeletons convey significant information for human action recognition. Conventional approaches for modeling skeletons usually rely on hand-crafted parts or traversal rules, thus resulting in limited expressive power and ...

Quo Vadis, Action Recognition? A New Model and the Kinetics Dataset [PDF]
Computer Vision and Pattern Recognition, 2017 The paucity of videos in current action classification datasets (UCF-101 and HMDB-51) has made it difficult to identify good video architectures, as most methods obtain similar performance on existing small-scale benchmarks. This paper re-evaluates state-

Disentangling and Unifying Graph Convolutions for Skeleton-Based Action Recognition [PDF]
Computer Vision and Pattern Recognition, 2020 Spatial-temporal graphs have been widely used by skeleton-based action recognition algorithms to model human action dynamics. To capture robust movement patterns from these graphs, long-range and multi-scale context aggregation and spatial-temporal ...

PYSKL: Towards Good Practices for Skeleton Action Recognition [PDF]
ACM Multimedia, 2022 We present PYSKL: an open-source toolbox for skeleton-based action recognition based on PyTorch. The toolbox supports a wide variety of skeleton action recognition algorithms, including approaches based on GCN and CNN. In contrast to existing open-source

A Closer Look at Spatiotemporal Convolutions for Action Recognition [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 In this paper we discuss several forms of spatiotemporal convolutions for video analysis and study their effects on action recognition. Our motivation stems from the observation that 2D CNNs applied to individual frames of the video have remained solid ...

Learning Discriminative Representations for Skeleton Based Action Recognition [PDF]
Computer Vision and Pattern Recognition, 2023 Human action recognition aims at classifying the category of human action from a segment of a video. Recently, people have dived into designing GCN-based models to extract features from skeletons for performing this task, because skeleton representations
