Abstract: We propose a Dynamic Graph-Based Spatial-Temporal Attention (DG-STA) method for hand gesture recognition. The key idea is first to construct a fully-connected graph from a hand skeleton. Then, the node features and edges are automatically learned via a self-attention mechanism that performs in both spatial and temporal domains. We further propose to leverage the spatial-temporal cues of joint positions to guarantee robust recognition in challenging conditions. We carry out extensive experiments on benchmarks (DHG-14/28 and SHREC’17) and prove the superior performance of our method compared with the state-of-the-art methods.
