Video feature extraction method, device and computer device

Abstract

The present invention provides a video feature extraction method, a video feature extraction device and a computer device. The video feature extraction method includes the following steps that: a target video is divided according to a predetermined unit time length; at least two frames of images included in video segments are obtained; the at least two frames of images are identified, feature information contained in the images is obtained, and the image feature information of the video segments is obtained according to the feature information included in the images; the text feature information of the video segments is obtained according to the caption recognition result of each frame of image and the real-time speech recognition result of the video segments; semantic analysis is performed, so that the feature information of the video segments is obtained; and a mapping relationship between the feature information of the video segments and the target video is established. With the video feature extraction method, the video feature extraction device and the computer device of the invention adopted, the feature information of the video can be automatically extracted through image video and audio recognition technology, and the extraction of the feature information is refined to the dimension of the video segments of unit time length in the video, and therefore, the obtained feature information is more comprehensive.

Description

technical field [0001] The present application relates to the technical field of video management, in particular to a video feature extraction method, device and computer equipment. Background technique [0002] Existing video content management, such as the director, leading actor, year and / or plot brief of video media properties, are all manually configured, generally based on video albums, and the smallest granularity is just a single video under the album. There is little maintenance for attribute tags for single videos. Among them, the attribute of video media assets includes some basic media information information of the video, such as director, leading actor, year, plot brief introduction, online time and / or update time and so on. Video album is currently the most important object of video media asset attribute maintenance. A video album includes feature films and sideshow videos of a movie or series. [0003] The video content management in the existing related te...

Problems solved by technology

[0004] The biggest disadvantage of the existing technical solutions is that the video attributes need to be maintained manually, and the labor cost is high; and the video attributes are maintained at the video album level, which leads to incomplete and detailed video attributes; for example, the 2017 popular variety show "See Words" There is a letter in Rumian Season 2 that mentions Jiang Wen, Ge You, and Zhou Runfa, but there is no such information in the video attributes
