Abstract

The invention provides a model training method and device, a video classification method and device, equipment and a storage medium, relates to the field of artificial intelligence, in particular to the technical field of computer vision and deep learning, and can be specifically applied to smart cities and intelligent traffic scenes. The specific implementation scheme is as follows: determining a video classification result of each video frame in a sample video by using a pre-trained video classification model; determining a salient frame in the sample video according to the video classification result of each video frame and the annotation classification result of each video frame in the sample video; and training a significant frame determination model based on the significant frame. According to the implementation mode, the salient frame can be selected from the video, and the accuracy of candidate video classification is improved.

Description

Technical field [0001] The present disclosure relates to the field of artificial intelligence, and specific to computer vision and depth learning technology, in particular to model training, video classification methods, devices, equipment, and storage media, specific for smart cities and intelligent transportation scenes. Background technique [0002] High efficiency video recognition, that is, the given video content completes the category specified in the case of computing accuracy and speed and computational cost. As one of the more active research topics in the computer vision community, efficient video recognition is widely used in video surveillance, video recommendation, search and other scenes. Although video recognition has made great progress in recognition accuracy, it is still not a simple task in the case of guaranteed accuracy. Inventive content [0003] This disclosure provides a model training, video classification method, device, device, and storage medium. [...
