Abstract

The invention relates to a video processing method and device, electronic equipment and a storage medium. The video processing method comprises the steps: determining a plurality of target video frames in a plurality of video frames of a to-be-processed video; respectively carrying out feature extraction processing of a plurality of channels on the plurality of target video frames to obtain firstfeature maps of the plurality of channels of the target video frames; performing space-time extraction processing on the first feature map of the target video frame to obtain space-time feature information of the target video frame; and recognizing the to-be-processed video according to the space-time feature information to obtain a recognition result. The video processing method obtains the spatial-temporal feature information through sequential replacement processing and feature extraction processing, and does not need to use modes such as optical flow or three-dimensional convolution with large operation expenditure to obtain the spatial-temporal feature information, so that the processing efficiency is improved, and good spatial-temporal feature information expression capacity can be obtained under the condition that the number of parameters of the neural network is not increased.

Description

technical field [0001] The present disclosure relates to the technical field of computers, and in particular to a video processing method and device, electronic equipment and storage media. Background technique [0002] Video recognition is a very challenging task in the field of computer vision and artificial intelligence, and has a wide range of applications in the real world. For example, in terms of short video applications, if you can accurately understand the content of the entire short video, you can recommend different content for different customers, and realize personalized content recommendation for thousands of people. In the field of security monitoring, accurate identification of abnormal behavior events in the video can play a very positive role in preventing and suppressing dangerous behaviors in time. Compared with image recognition, video recognition includes video timing information, which can be used to further help video recognition. In related technol...
