Abstract

The invention discloses a dual model fusion-based video behavior segmentation method and apparatus. The method comprises the steps of segmenting a video into clips based on a correlation coefficient between adjacent video frames in the video; for the video frames in the clips, identifying scenes of the video frames to obtain scene eigenvectors; for the video frames in the clips, identifying localbehavior features of the video frames to obtain local behavior eigenvectors; based on the scene eigenvectors and the local behavior eigenvectors, identifying behavior types of the video frames and confidence degrees corresponding to the behavior types; based on the behavior types and the confidence degrees of the video frames of the clips, determining the behavior types of the clips; and combiningthe adjacent clips with the same behavior types to obtain a segmentation result of the video. According to the method, dual models can be fused at the same time; and the overall behavior informationis extracted by comprehensively utilizing two dimensions including the scenes and local behaviors, so that the video is quickly segmented.

Description

technical field [0001] The present application relates to the field of automatic image processing, in particular to a video behavior segmentation method and device based on two-way model fusion. Background technique [0002] The rapid development of video compression algorithms and applications has brought massive video data. Videos contain a wealth of information. However, due to the huge amount of video data, unlike text that directly expresses abstract concepts, the extraction and structuring of video information is relatively complicated. At present, the video information extraction method is mainly to segment the video first, and then classify and label each segment after segmentation, which is an idea of ​​video information extraction and structuring. Segmenting video based on traditional computer vision generally requires manual design of image features, which cannot flexibly adapt to changes in various scenes. Most of the currently available video segmentation is o...
