Embodiment Construction

[0061] The applicant found that: the current video clip label recognition technology uses the image features in the video clip as the basis for label recognition, which leads to low accuracy of the label recognition result. Moreover, the current video clip label recognition technology only determines the video clip's label in a certain dimension, which results in a relatively single label recognition result for the video clip. For example, action labels such as singing, dancing, running, etc. are identified in the behavioral dimension. For example, emotional labels such as laughing, crying, and surprise are identified in the emotional dimension.

[0062] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. ...

Abstract

The invention provides a video clip tag identification method. The method comprises the steps of obtaining a target video clip; extracting image features and audio features of the target video clip; and analyzing image features and audio features of the target video clip by using a pre-trained multi-label classification model to obtain a tag classification result of the target video clip, the label classification result of the target video clip comprising category labels of the target video clip in at least two dimensions. Based on the scheme provided by the invention, the tag of the target video clip can be comprehensively identified, and the accuracy of a tag identification result can be improved.

Description

technical field [0001] The present application belongs to the technical field of video recognition, and in particular, relates to a method and device for video segment label recognition. Background technique [0002] With the rapid development of network technology and multimedia technology, a large amount of video information emerges in front of users. Such video information enriches the user's life, however, the richness of video information comes at the cost of unstructuredness. [0003] When it is necessary to find the desired video clip from a large number of videos, the tag recognition technology of the video clip becomes more and more important. Moreover, the tags of video clips play an important role in improving the recommended distribution effect of video clips, automatically and accurately advertising, establishing content retrieval capabilities of video clips, and generating video highlights of specific content. [0004] However, the applicant found that: the c...
