Embodiment Construction

[0080] 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.

[0081] refer to figure 1 , which shows a flow chart of the steps of a method for processing video data according to an embodiment of the present invention, which may specifically include the following steps:

[0082] Step 101, acquiring comment information added by a user to video data.

[0083] In a specific implementation, during the process of watching the video data, the user may mark the video with comment information according to his or her perception of the video data.

[0084] For example, actor Zhang San's performance in a certain scene is very vivid, and the user may add comment information at this time, "Zhang San is too funny", "Zhang San's eyes are amazing", etc., actor Li Si's performance in a certain scene is inacc...

Abstract

Embodiments of the present invention provide a method and device for processing video data, the method comprising: obtaining comment information added by users to video data; identifying emotional information expressed by the comment information; Marking feature video frames in the video data; generating feature video clips in the video data according to the density of the feature video frames. Since the user's comment information is an objective existence relative to the technical staff, it can greatly reduce the subjectivity of labeling video data, improve the recognition accuracy of emotional information, and greatly reduce the cost of manual labeling; in addition, using density clustering feature video clips , it can avoid the discreteness and fragmentation of time, and in the case of ensuring the splendor of the feature video clips, it can ensure that the clustered feature video clips have a certain continuity and improve the viewing quality. Moreover, using density clustering, you can Avoid complex distance calculations and improve processing speed.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video data processing method and device. Background technique [0002] At present, there are many video resources, not only movies, TV dramas, variety shows, but also micro movies, selfie videos, etc., making video viewing an increasingly important part of people's entertainment life. [0003] In the video data, there are both parts that users are interested in and parts that are not of interest. In order to allow users to watch the parts they are interested in and reduce the waste of time, currently supervised learning algorithms are usually used to analyze the behavior data of users who have watched videos, and mining Find video clips that are mostly of interest to users who have watched the video, and provide these video clips to users who have not watched the video. [0004] The supervised learning algorithm needs to manually mark the tags of the video cli...
