Problems solved by technology

[0005] In view of this, the present invention provides a video clip processing method, device, and computer-readable storage medium, which solves the problem that the entire behavior clip needs to be used as a video input when determining the category of the behavior clip in the current solution to a certain extent. Extracting features and classifying them increases the problem of time consumption

Abstract

The invention provides a video clip processing method, a video clip processing device and a computer readable storage medium. The video clip processing method comprises the following steps: extractingvideo features of a video sample and a video time sequence corresponding to the video features; Generating a target video clip according to the video feature and a preset behavior clip generation model, the target video clip comprising a clip time sequence; Determining a target video feature corresponding to the target video clip from the video features according to the matching of the clip timesequence and the video time sequence; Inputting the target video features into a preset behavior category classifier, and obtaining the classification category of action behavior in the target video clip. The corresponding time sequence in the video features is utilized to find the target video feature input classifier corresponding to the target video segment, so that repeated feature extractionon the target video segment is avoided, and the classification efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and device for processing video clips and a computer-readable storage medium. Background technique [0002] It is of great significance for subsequent video analysis to extract the behavior clips that users are interested in from unprocessed long videos and determine the behavior categories of the behavior clips. In practical applications, richer personalized services can be provided to users. [0003] In the prior art, a two-stream network model based on a boundary-sensitive network is usually used to extract image features and optical flow features of video samples respectively, and fuse the image features and optical flow features to obtain fused features. Among them, the optical flow feature is generated by the movement of the foreground object itself in the video sample, the camera movement, or the joint motion of the two, and expresses the relevant l...
