Abstract Aiming at the spatio-temporal modeling in video action recognition, a temporal enhanced action recognition algorithm based on fused spatio-temporal features is proposed under the deep learning framework. To lower the cost of video-level temporal modeling, a sparse sampling strategy is employed to adapt to video duration changes. In the recognition stage, temporal difference between adjacent feature maps is calculated to enhance the motion information in the feature level. The combination of residual structure and temporal enhanced structure is introduced to further improve the representation ability of the network. Experimental results show that the proposed algorithm obtains higher accuracy on UCF101 and HMDB51 datasets and achieves better results in the actual industrial operation recognition scene with a smaller network scale.
