Problems solved by technology

However, the supervised learning scheme needs to manually label each sample in advance, and the number of samples is generally large. Manual labeling is not only time-consuming and error-prone, but the accuracy of the trained model is not high.

Abstract

The invention discloses a video feature extraction method, device and equipment and a computer storage medium, and belongs to the technical field of video processing, and the method comprises the steps: employing a topic tag added during the release of a sample video as a real video tag during the training of a video feature extraction model, does not need to carry out the manual marking, and improves the training efficiency. The problem of high error rate caused by manual annotation is avoided, the accuracy of the model obtained by training is improved, and the efficiency of model training is higher. Moreover, the topic tag added when the sample video is published is generally closely related to the video content, so that the video semantics can be expressed more accurately, and the topic tag is more fit with the actual video application scene, and therefore, the model obtained by training can accurately express the semantic content of the video, and the video semantic content can be more accurately expressed. And an actual video application scene can be met.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of video processing technology, and provides a video feature extraction method, device, equipment and computer storage medium. Background technique [0002] Video is currently an important way to obtain information on the Internet. Taking short videos as an example, short videos are an extremely important content carrier in current information flow products. A comprehensive and accurate understanding of short videos is the key to realizing the retrieval, aggregation and retrieval of short videos. The premise of functions such as class, recommendation or search. In addition to common basic features such as video classification and tags, video content understanding also includes converting videos into a series of digital features with semantic information. How to comprehensively and accurately characterize video content features is the most challenging issue i...
