Abstract

The invention discloses a video action detection method and device, electronic equipment and a storage medium, and relates to the technical field of video processing, the method comprises the steps: acquiring an original feature sequence of a target video, wherein the original feature sequence comprises original features corresponding to each frame of image in the target video; inputting the original feature sequence into an action boundary prediction model for action boundary prediction to obtain an action boundary prediction value corresponding to each frame of image; performing boundary enhancement processing on the original features corresponding to each frame of image based on the motion boundary predicted value corresponding to each frame of image to obtain a boundary enhancement feature sequence of the target video; and inputting the boundary enhancement feature sequence into a video action detection model for video action detection to obtain an action detection result of the target video, the action detection result comprising start-stop position information of an action in the target video. By using the technical scheme provided by the invention, the precision and reliability of video action detection can be improved.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a video motion detection method, device, electronic equipment and storage medium. Background technique [0002] With the explosive growth of Internet information, video has gradually become an important part of Internet information. The purpose of video action detection is mainly to obtain information such as the start time and end time of the action in the video, and the category of the action; video action detection The development of technology has brought great help to businesses such as video content understanding and content review. [0003] Since the change of motion in the video is often slow and not obvious, it is difficult to obtain the precise start time and end time of the motion, resulting in low accuracy and low reliability of video motion detection. Therefore, a more reliable solution needs to be provided. Contents of the invention [0004] In...
