Problems solved by technology
[0002] At present, monitoring equipment generally records 24 hours a day. Therefore, when a case occurs or when it is necessary to check the video to find clues, it takes a lot of time to check the video.
The existing condensed playback or video summarization technology is not mature enough, its recognition rate is low, and it is easy to miss or miss important clues
In order not to miss any clues, users usually watch videos manually, which requires a lot of manpower and time

The invention relates to the field of videos, and discloses a video playing method and an apparatus thereof. The video playing method includes following steps: conducting statistics of a continuous area for movement change of two adjacent frames; determining the continuous area to be the changing object if the area of the continuous area is larger than a predetermined threshold; obtaining the playing grade of the frame according to the area of the continuous area of the determined changing object; and playing the frame at the corresponding playing speed according to the playing grade of the frame. According to the method and the apparatus thereof, the playing speed of the whole video is adjusted according to the change of the video image, when the image of the video frame changes a lot, the playing speed is slowed down, and vice versa; the overall time for video playing is reduced, the time consumed by the check of monitoring video in the process of case investigation is reduced, the manpower cost and the time cost are lowered, and the case-handling efficiency is improved.
Description
technical field [0001] The invention relates to the field of video monitoring, in particular to a video playing technology. Background technique [0002] At present, monitoring equipment generally records video 24 hours a day, so when a crime occurs or it is necessary to check the video to find clues, it takes a lot of time to check the video. The existing condensed playback or video summarization technology is not mature enough, its recognition rate is low, and it is easy to miss or miss important clues. In order not to miss any clues, users usually watch videos manually, which requires a lot of manpower and time. Contents of the invention [0003] The purpose of the present invention is to provide a video playback method and device thereof. The present invention can adjust the playback speed of the entire video according to the size of the motion change of the video picture, and slow down the playback speed when the picture or size of the video frame changes greatly. ,...
