Dynamic information enhanced behavior identification method and device

Abstract

The invention provides a dynamic information enhanced behavior recognition method and device. The method comprises the following steps: determining an image sequence of a video to be recognized; the image sequence is input into a behavior recognition model, a behavior recognition result output by the behavior recognition model is obtained, and the behavior recognition model is obtained through training based on the sample image sequence of the sample video and the sample behavior recognition result; wherein the behavior recognition model is used for performing feature extraction on each frame of image in the image sequence to obtain an apparent feature map sequence, performing differential operation on every two adjacent apparent feature maps in the apparent feature map sequence to obtain a dynamic feature map sequence, and performing feature coding on the dynamic feature map sequence and the apparent feature map sequence to obtain dynamic feature representation; and behavior identification is carried out based on the dynamic feature representation. According to the method, the device, the electronic equipment and the storage medium provided by the invention, while the accuracy of behavior recognition is improved, the real-time performance of behavior recognition is also improved, and the application value is higher.
