Abstract Inspired by the mechanism of human visual perception, a temporal group deep network action recognition algorithm based on attention mechanism is proposed under the framework of deep learning. Aiming at the deficiency of local temporal information in describing complex actions with a long duration, the video packet sparse sampling strategy is employed to conduct video level time modeling at a lower cost. In the recognition stage, channel attention mapping is introduced to further utilize global feature information and capture classified interest points, and channel feature recalibration is performed to improve the expression ability of the network. Experimental results on UCF101 and HMDB51 datasets show that the recognition accuracy of the proposed algorithm is high.
