Problems solved by technology

[0004] However, according to the current video query technology, the accuracy is not high. When performing video query based on the media containing the target object, when a candidate video includes the target object but the target object is in motion, the candidate video often cannot be queried. select video

Embodiment Construction

[0030] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0031] Because in video query, if there is a moving target object in the candidate video, the video features of the candidate video obtained by traditional video query technology cannot accurately reflect the actual content in the candidate video, that is, the Moving objects will be difficult to be accurately captured and reflected in the corresponding video features, resulting in that even if the target object is included in the media to be checked for query, it is not easy to identify that the candidate video is related to the media to be checked. Video queries are less accurate.

[0032] To this end, the embodiment of the present application provides a video query method. When determining the video features of the candidate video, the timing information of the moving object in the candidate video is used to effectively avoid the original moving object in the vi...

Abstract

The embodiment of the invention discloses a video query method, and when a user needs to query a to-be-queried video, the method can obtain media features of the to-be-queried media and image featurescorresponding to alternative videos. The to-be-checked media comprises a target object, and the alternative video comprises a moving object. Video characteristics of the alternative video are determined according to the image characteristics and the motion time sequence information of the motion object in the alternative video. Due to the fact that the information embodied by the moving object inmovement can be accurately captured through the movement time sequence information, the determined video features can accurately describe the moving object, and adverse effects caused by an originalmoving object in video query are effectively avoided. Therefore, whether the moving object in the alternative video is related to the target object in the to-be-queried media or not can be accuratelydetermined according to the media characteristics and the video characteristics, and the query experience of a user is improved.

Description

technical field [0001] The present application relates to the field of media processing, in particular to a video query method and device. Background technique [0002] With the development of search and query technology, users can query videos related to the media through media such as pictures and videos. For example, users can query which candidate videos are available from the candidate videos through a piece of video that includes the target object. The object to be checked is included. [0003] Currently, content-based video query technology is commonly used to realize the above-mentioned services. [0004] However, according to the current video query technology, the accuracy is not high. When performing video query based on the media containing the target object, when a candidate video includes the target object but the target object is in motion, the candidate video often cannot be queried. Choose a video. Reduce the user's query experience. Contents of the inv...
