Document Type and Number:
WIPO Patent Application WO/2021/093468
Kind Code:
A1
Abstract:
Disclosed are a video classification method and apparatus, a model training method and apparatus, a device and a storage medium, wherein same fall within the technical field of computer vision. The method comprises: acquiring a video; selecting n image frames from the video; extracting respective feature information of the n image frames by means of a feature extraction network and according to a learned feature fusion strategy; and determining a classification result of the video according to the respective feature information of the n image frames. In the feature fusion strategy in the embodiments of the present application, only simple information fusion between adjacent image frames is required, and there is no need to perform convolution in both spatial and temporal dimensions as there is in three-dimensional convolution; and in the feature fusion strategy, complex and repetitive three-dimensional convolution operations are replaced with simple feature information fusion, and the amount of work is small, such that it takes less time to finally obtain a classification result of a video, and the efficiency is high.
