Embodiment Construction

[0036] Based on the background technology, it can be seen that the existing automatic segmentation technology of video news is generally based on shots, and generally video frame sequences are first clustered into shot sequences. That is to say, the existing automatic segmentation technology of video news generally regards the starting point or end point of the shot as the segmentation point of the video news, so as to divide the video news into a plurality of different video segments. However, this shot-based video news segmentation technology can only split the video clips of different shots, but cannot split the video clips inside the shot, so it is possible to divide different news items into one video clip For example, the video footage of the host summarizing the content of the previous news and then broadcasting the next news will be divided into one video segment, so that the divided single video segment may contain the information of multiple news items, As a result, ...

Abstract

The invention provides a video news segmentation method. The video news segmentation method is a video news segmentation method based on a news headline and a mute point. For a shot in which a plurality of news headlines are present, the shot is subdivided into sub-shots according to the headlines and mute points in the shot, so separation of a video segment inside the shot is implemented, and theperformance of video news segmentation is improved; and in addition, the invention further provides a video news segmentation apparatus.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a video news segmentation method and device. Background technique [0002] News videos contain a large amount of latest information, which is of great value to video websites and news applications. Video websites or news applications need to segment and launch the entire news that is broadcast every day, so that users can click and watch each piece of news they are interested in. Due to the large number of TV stations in the country, there are various local stations in addition to the satellite TV stations. If it is necessary to segment all the news, it will take a lot of manpower to segment. At the same time, due to the timeliness of news, the speed requirements for news video segmentation are also very strict, so it brings greater pressure to manual segmentation. News is broadcast in large quantities at a certain time (such as 12:00 noon). In order to ensure ti...
