Problems solved by technology

[0004] Among the above-mentioned methods, due to the large network structure and the large amount of calculated parameters, the processing speed is relatively slow
In addition, in the above several methods, when processing inter-frame information, global operations will be performed on individual frames, resulting in waste of computing resources; and because inter-frame information cannot be used, the classification results may be inaccurate

Abstract

The invention provides a video classification method and device, electronic equipment and a computer readable storage medium, and relates to the technical field of image processing. The video classification method comprises the steps: performing sparse sampling on a to-be-processed video to obtain a plurality of key frames; processing the plurality of key frames through a feature extraction network in a preset model to extract features of the plurality of key frames; and fusing the features of the plurality of key frames through a trained attention network in the preset model, and processing the fused features to obtain a classification result of the to-be-processed video. The video classification method can reduce the calculation amount, and improves the video classification speed and efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a video classification method, a video classification device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of video technology, users can obtain various videos from various channels. Since the number of videos is too large, by classifying and processing the videos, it is easy for the user to find and use the required videos, and user experience is improved. [0003] In related technologies, video classification methods may include methods based on long short-term memory networks, methods based on 3D convolution, and methods based on dual-stream networks. [0004] Among the above methods, the processing speed is relatively slow due to the large network structure and the large amount of parameters to be calculated. In addition, in the above several methods, when processing inter-frame infor...
