Abstract

The invention relates to the technical field of video processing, particularly provides a video clip positioning method and device and a medium, and aims to solve the problem of how to improve the positioning accuracy during video clip positioning. The method comprises the following steps: controlling a video positioning model to obtain a first fusion feature according to candidate features of candidate video clips in a video sample and language features of language description information, and acquiring a second fusion feature corresponding to the candidate video clips with the same starting time or ending time according to the first fusion feature by adopting a graph convolutional network; training a video positioning model according to the matching degree of the candidate video clip predicted by the second fusion feature and the language description information; and carrying out video clip positioning by adopting the trained model. Accurate candidate video clips can be obtained according to the first fusion features to improve the accuracy of video positioning, candidate video clips with semantics difficult to distinguish can be accurately distinguished according to the second fusion features, and the accuracy of video positioning is further improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, and specifically provides a video segment positioning method, device and computer-readable storage medium. Background technique [0002] At present, the video clip localization methods based on language query mainly include one-stage method and two-stage method. Specifically, the one-stage method mainly includes two methods. One method is to predict each frame in the video and judge whether it is the start frame or the end frame of the video segment related to the query language. Since this method It mainly predicts based on the content of the current frame, ignoring the global features of the video, resulting in poor prediction results; another method is to use all the frames in the real label video clip to regress the current frame and the starting frame and The distance of the end frame, according to the distance to judge whether the current frame is the start frame or the en...
