Abstract

The invention provides a video classification method and device. The video classification method comprises the following steps: receiving a classification task for a target video; in response to the classification task, extracting video frames of the target video, and generating a video frame set; determining an initial classification result of the target video based on the video frame set; selecting a target video frame from the video frame set; and carrying out key region detection on the target video frame based on the initial classification result, and determining a target classification result of the target video. According to the video classification method provided by the invention, video classification and key region detection are combined, so that videos with similar pictures can be classified more finely, and misclassification of videos can be reduced through key region detection, and the success rate of video classification is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a video classification method. The present application also relates to a video classification device, a computing device, and a computer-readable storage medium. Background technique [0002] With the rapid development of the Internet and mobile devices, the demand for browsing, recommending, and editing videos is also increasing day by day. As one of the basic capabilities, video classification has also been extensively researched and applied. [0003] With the development of artificial intelligence, the neural network has been extended from images to videos. Now it is possible to use deep learning algorithms to further classify videos using semantic features on the basis of traditional underlying features. When business needs arise, it is difficult for existing deep learning algorithms to distinguish videos with very similar features. Contents of the invention...
