Abstract

The invention relates to a video classification method, device and equipment, and a computer readable storage medium. The method comprises the steps of obtaining at least two key frame picture segments of a to-be-classified video; according to the time-space information of the at least two key frame picture segments, segment semantic vectors of the at least two key frame picture segments are acquired respectively; performing bidirectional association fusion on the at least two fragment semantic vectors to obtain a global to-be-classified semantic vector of the to-be-classified video; obtaininga prediction probability of the to-be-classified video according to the global to-be-classified semantic vector; wherein the prediction probability is used for determining a classification result ofthe to-be-classified video. By adopting the method, the video classification accuracy can be effectively improved.

Description

technical field [0001] The present application relates to the field of computer vision, in particular to a video classification method, device, equipment and computer-readable storage medium. Background technique [0002] With the continuous development and progress of science and technology, all kinds of short videos have begun to emerge in large numbers. In the face of a large number of various short videos with rich content, the combination of artificial intelligence and computer vision technology to realize video recognition and classification has become the mainstream technology of various video classification services. [0003] Traditional video classification methods mainly include two categories: one is to completely use the feature extraction network of the convolution structure to classify the video, and the other is to classify the video by combining the feature extraction network of the convolution structure and the loop structure. However, in practical applicat...
