Document Type and Number:
WIPO Patent Application WO/2021/159609
Kind Code:
A1
Abstract:
The present application is suitable for the technical field of video processing and provides a video lag identification method and apparatus, and a terminal device. The method comprises: when a monitoring state of a video is a first state and a face exists in the video, modifying the monitoring state into a second state; if the monitoring state is the second state, sampling the video to obtain N first image frames; if an image difference degree among the N first image frames is smaller than a first difference threshold, taking the earliest sampling moment as a lag starting moment, and setting the monitoring state as a third state; if the monitoring state is the third state, sampling the video to obtain M second image frames; and if an image difference degree among the M second image frames is greater than or equal to the first difference threshold, taking the latest sampling moment as a lag termination moment of the video, setting the monitoring state as the first state, and identifying a lag time period of the video. According to the embodiment of the present application, precise identification on the start and end of lag is achieved, and precise identification of a lag time period is achieved.
