Problems solved by technology

[0005] Nowadays, such as the segmentation of news videos, etc. are all based on relying on manual work, that is, manually judging the position of the segmentation, which often requires manual browsing of each frame of the video, which requires a huge workload and consumes a lot of time and labor costs.
[0006] Due to the rapid growth of the number of videos in the network environment, the way of manually segmenting video data is getting higher and higher in terms of time and labor costs, which is unbearable

Embodiment Construction

[0087] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0088] One of the core concepts of the embodiments of the present invention is that in video data such as news videos, there are some obvious structural features in the story structure, such as announcers, subtitles, camera cuts, mute points, etc., which can be automatically generated by a computer. Complete some or all of the segmentation work.

[0089] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for segmenting video data according to the present invention, which may specifically include the following steps:

[0090] Step 101, separating audio data and video image data from video data;

[0091] Video can generally refer to various technologies that capture, record, process, store, tran...

Abstract

An embodiment of the invention provides a video data partitioning method and device. The method comprises steps as follows: separating audio data and video image data from video data; performing video feature detection on the audio data and the video image data to acquire one or more candidate partition points; selecting one or more target partition points from the one or more candidate partition points; partitioning the video data according to the one or more target partition points to acquire multiple pieces of video sub-data. With the adoption of the video data partitioning method and device, automatic partitioning of the video data is realized, the manual interference operation is greatly reduced, the partitioning time is greatly shortened, and the labor cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of video data processing, in particular to a video data segmentation method and a video data segmentation device. Background technique [0002] In recent years, with the rapid development of the Internet, the amount of information on the Internet has increased dramatically, including a large amount of video data, such as news videos, variety shows, and so on. [0003] Since many video data are a large whole, which contains multiple paragraphs, for example, a complete news video often includes multiple news clips. [0004] Therefore, it is often necessary to segment the video data to obtain the included paragraphs. [0005] Nowadays, the segmentation of news videos, etc. are all based on manual judgment, that is, the position of segmentation is manually judged. This often requires manual browsing of each frame of the video, which is a huge workload and consumes a lot of time and labor costs. [0006] Due to...
