In video action recognition, effective spatiotemporal modeling is crucial. However, traditional two-stream methods face challenges in integrating spatial information from RGB images and temporary information from optical flow without long-range temporal modelling. To address these limitations, we propose the Deep Fusion Module (DFM), which focuses on the deep fusion of spatial and temporal information and consists of two components. First, we propose an Attention Fusion Module (AFM) to effectively fuse the shallow features obtained from a two-stream network, thereby facilitating the integration of spatial and temporal information. Next, we incorporate a SpatioTemporal Module (STM), comprising a ConvGRU and a 1×1 convolution, to model long-range temporal dependency and fuse spatial-temporal features. Experiments on the UCF101 dataset show that our method achieves 96.5% accuracy, outperforming baseline two-stream models by 0.3%.
