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 invention provide a video data processing method and apparatus. The method comprises the steps of obtaining comment information added for video data by a user; identifying emotion information expressed by the comment information; according to the emotion information, marking feature video frames in the video data; and generating feature video clips in the video data according tothe density of the feature video frames. The comment information of the user is objective existence relative to a technical staff, so that the subjectivity of marking the video data can be greatly reduced, the identification accuracy of the emotion information is improved, and the manual marking cost is greatly reduced; in addition, the feature video clips are clustered by using the density, so that the discreteness and fragments of time can be avoided, the clustered feature video clips can be ensured to have a certain continuity under the condition of ensuring the wonderfulness degree of thefeature video clips, and the watching quality is improved; and moreover, due to the clustering by using the density, complex distance calculation can be avoided and the processing speed is increased.

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...
