Embodiment Construction

[0030] As mentioned in the background art, manual annotation not only consumes a lot of manpower and time, but also often has a lot of subjectivity, which cannot accurately and fairly describe the video content. In addition, the prior art can only search video titles, and the accuracy of search results formed by video retrieval is low.

[0031] The technical solution of the present invention performs image recognition on the video file, and uses the target object information contained in the video file as the keyword of the video file, at least when searching the video file, the video file containing the specified target can be searched, It avoids the need to manually annotate the video in the prior art, and can only search the video title, ensures the comprehensiveness of video keyword selection, and then realizes the comprehensiveness of the video file search.

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, s...

Abstract

The invention discloses a video keyword determination method and device, a video retrieval method and device, a storage medium and a terminal. The video keyword determination method comprises the steps of obtaining a to-be-processed video file; and performing image recognition on the video file to obtain target object information of a target object contained in the video file, and adding the target object information into a keyword of the video file, the keyword being at least used for searching the video file. According to the technical scheme, comprehensiveness and convenience of video keyword selection can be guaranteed, and accuracy of video search is improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a video keyword determination, video retrieval method and device, storage medium, and terminal. Background technique [0002] Unlike ordinary information retrieval, video search is usually complex. Traditional video retrieval requires manual annotation to obtain relevant information of the video, such as video summaries, etc., and store this information in the database for subsequent queries. That is to say, the retrieval of the video requires the user to analyze the content of the video in advance. [0003] However, manual annotation not only consumes a lot of manpower and time, but also often has a lot of subjectivity, which cannot accurately and fairly describe the video content. In addition, the prior art can only search video titles, and the accuracy of search results formed by video retrieval is low. Contents of the invention [0004] The te...
