"Focal and Global Spatial-Temporal Transformer for Skeleton-Based Actio" by Zhimin Gao, Peitao Wang et al.

Despite great progress achieved by transformer in various vision tasks, it is still underexplored for skeleton-based action recognition with only a few attempts. Besides, these methods directly calculate the pair-wise global self-attention equally for all the joints in both the spatial and temporal dimensions, undervaluing the effect of discriminative local joints and the short-range temporal dynamics. In this work, we propose a novel Focal and Global Spatial-Temporal Transformer network (FG-STFormer), that is equipped with two key components: (1) FG-SFormer: focal joints and global parts coupling spatial transformer. It forces the network to focus on modelling correlations for both the learned discriminative spatial joints and human body parts respectively. The selective focal joints eliminate the negative effect of non-informative ones during accumulating the correlations. Meanwhile, the interactions between the focal joints and body parts are incorporated to enhance the spatial depe ....

"Motion saliency based hierarchical attention network for action recogn" by Zihui Guo, Yonghong Hou et al.

Skeleton data is widely used in human action recognition for easy access, computational efficiency and environmental robustness. Recently, encoding skeleton sequences into color images becomes a popular preprocessing procedure to make use of the spatial modeling ability of convolutional neural network (CNN). Furthermore, inspired by relevant work in other fields, attention mechanism has been introduced to CNN based skeleton action recognition. In this paper, we propose a two-branch hierarchical attention model (HAN) for skeleton based action recognition. The proposed model consists of a base branch for spatial-temporal feature extraction and an attention branch for feature enhancement. In attention branch, we utilize auxiliary feature instead of intermediate feature to generate attention maps. Specifically, variance vectors of skeleton sequences are fused as motion saliency matrices to determine the contributions of each joint. Then the motion saliency matrices are sent into the hierar ....
