Abstract
The invention provides a spatiotemporal enhancement network based video action recognition method, including: S1. equally partitioning a video into T time periods, and randomly sampling one frame from each time period, to obtain an input sequence with T frames of image; S2. preprocessing the image sequence acquired in S1; S3. taking a tensor obtained in S2 as an input, inputting the tensor into a spatiotemporal enhancement network, by which spatial and temporal features are extracted; and S4. activating and normalizing the spatial and temporal features by softmax, averaging the normalized spatial and temporal features along a time dimension, obtaining classification scores of behaviors in videos through transformation, and then taking a label corresponding to the highest score as the classification result. A spatiotemporal enhancement module is embedded in a spatial network, so that better classification accuracy can be obtained by a deep learning based video behavior recognition system herein.
