Abstract:

To address insufficient spatiotemporal feature coupling and the inadequate utilization of multimodal information in dance motion recognition, a multi-modal fusion Beat STMAN (Beat-guided Spatio-Temporal Multimodal AMAA-Net Network) network recognition method was proposed to improve the accuracy of dance action recognition. Firstly, this method is based on the skeleton based ST-GCN (Spatial Temporal Graph Convolutional Network) model to construct a spatiotemporal convolutional skeleton network. To cope with the unfavorable factors of continuous and varied dance movements and partially obscured movements, a dynamic adjacency matrix was integrated with a multi-head spatial attention mechanism to automatically capture global human-body topology parameters. Secondly, an audio stream information feature extraction alignment fusion method was proposed to obtain beat timestamp pulse sequences, and a Transformer multi-head attention mechanism was used to design a cross-modal fusion module AMAA-Net, which achieved multimodal feature fusion through a resistance game mechanism, effectively alleviating insufficient model feature fusion. Finally, the Beat-STMAN was evaluated on a publicly available dance dataset to verify its effectveness. Experimental results showed that for the Thomas spin movement, the recognition rate of the proposed model achieved 14.7% higher than that of the ST-GCN model, demonstration significantly improved robustness in occluded scenarios. Furthermore, ablation experiments verified that the integration of the dynamic adjacency matrix, multi-head attention mechanism, and cross-modal attention mechanism could effectively fuse audio-action correlation features, with a cross-modal contribution rate reaching 5.3%. This effectively improved the model’s Top-1 accuracy, thereby enhancing the model’s prediction precision and providing a multimodal technical implementation path for dance-teaching evaluation and immersive interaction.
