Embodiment Construction

[0014] The present invention will be further described below.

[0015] The technical scheme that this embodiment mode adopts is: it comprises the following steps:

[0016] 1. Separate the audio and video streams from the input video, and synchronize the audio and video streams according to the timestamp;

[0017] 2. Use object tracking technology to segment the scene of the video, and roughly separate the scene fragments;

[0018] 3. Perform speech recognition on the audio clips corresponding to each scene clip, and segment the scene clips according to the recognized text: for the scene clips that can recognize the text, separate the text paragraphs through the text classification method, and subdivide each scene clip according to the paragraphs ; For the scene segment that cannot recognize the text, perform step 4;

[0019] 4. According to the rhythm of the audio, voiceprint and other information, the scene segment is subdivided: for the scene segment where the text cannot ...

Abstract

The invention discloses an intelligent stripping method based on the separation of audio and video. The specific steps are: separating the audio and video streams from the input video; using object tracking technology to segment the scene of the video, and roughly separating the scene segments; Speech recognition is performed on the audio clips corresponding to each scene clip, and the scene clips are subdivided according to the recognized text; or the scene clips are subdivided according to the rhythm of the audio, voiceprint and other information; using deep learning technology, based on video understanding, the video clips are sorted label; finally, return the stripped video segment with the label; the method of the present invention effectively improves the efficiency and accuracy of video stripped.

Description

technical field [0001] The invention relates to the technical field of media asset management, in particular to an intelligent splitting method based on audio and video separation. Background technique [0002] Driven by the technology of mobile Internet, big data, and AI intelligence, short videos are breaking the traditional thinking of the content industry with their own advantages. With the development of 5G technology, the operating cost of the platform is reduced, the speed of the mobile terminal is greatly improved, the traffic of the short video blowout and the outstanding marketing effect are greatly improved, and the social activity and stickiness of users are greatly improved, which is more and more in line with the time of mobile users. Fragmented experience. But at the same time, how to accurately split long videos into multiple independent short videos based on content information of different natures has become an urgent problem to be solved. The traditional...
