Problems solved by technology

[0017] 1. Firstly, the summary generated is displayed in the cut form of the video, which is not intuitive enough for users to understand the content of the video at a glance
[0018] 2. This kind of customized video summary is often static, which ignores the part that the user really wants to know
[0019] 3. The video summary automatically generated by the system is too random and not representative

Abstract

The invention discloses a keyword-based video abstract generation method, which comprises the following steps of: performing visual channel processing on a video, and performing keyword-based visual content abstract extraction to obtain an image abstract; preprocessing the video voice text content, and performing keyword-based voice text content abstract extraction to obtain a text abstract; and obtaining a final image-text abstract by utilizing the image abstract and the text abstract. The invention provides the method for automatically generating the video abstract, so that the manual operation time of a video uploader is greatly reduced; the requirements of a video search user are fully considered, and a video abstract which is more suitable for the search intention of the user is provided for the user; by using the method based on the artificial intelligence deep learning technology, the generated video abstract can reflect the content of the video more accurately.

Description

technical field [0001] The invention relates to the fields of artificial intelligence and computer vision, in particular to a keyword-based method for generating video summaries. Background technique [0002] Video summarization technology has been proposed since the 1990s. As a research hotspot and difficulty, it has received continuous attention from many research teams at home and abroad. Theoretically, video is an image set obtained by combining a series of video frames according to event sequence or spatial distribution rules, which can express semantic information from multiple angles. However, video summarization should not only analyze the original video stream, but also comprehensively consider multimedia information such as meaningful audio streams and text streams accompanying the video. [0003] Video summarization refers to the use of computer technology to analyze the video structure, understand the video content, and select representative and meaningful parts...
