Title:
BEHAVIOR RECOGNITION METHOD AND SYSTEM, ELECTRONIC DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/180030
Kind Code:
A1
Abstract:
A behavior recognition method and system, comprising: intercepting video data into a plurality of video clips, performing frame extraction processing on each video clip to obtain frame images, and performing optical flow extraction on the frame images to obtain optical flow images; respectively performing feature extraction on the frame images and the optical flow images of each video clip to obtain feature maps of the frame images and the optical flow images of each video clip; respectively performing space-time convolution processing on the feature maps of the frame images and the optical flow images, and determining a space prediction result and a time prediction result of each video clip; fusing the space prediction results of all the video clips to obtain a space fusion result, and fusing the time prediction results of all the video clips to obtain a time fusion result; and performing double-flow fusion on the space fusion result and the time fusion result to obtain a behavior recognition result. The present invention can guarantee convolution effect, reduce calculated amount and weight, be associate with multiple pictures to process time sequence information among the pictures, and improve recognition accuracy.
