Embodiment Construction

[0029] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0030] The present invention proposes a method for automatic cataloging of news videos, such as figure 1As shown, the method can automatically catalog the news video programs, and recognize the headline text information in the news programs as the semantic information of the news stories. The cataloging method mainly works by identifying the appearance of subtitles, hosts and audio mute points in the news video, and through a comprehensive analysis of the above information, determines the time point of segmentation and the information of the news title. The news automatic cataloging system can perform operations such as cataloging, browsing, playin...

Abstract

The invention relates to a method and a system for cataloging news video. The method realizes automatic cataloging of the news video based on caption bars, anchorman and audio mute point information in a news program, and comprises the following steps: carrying out audio-video separation of news video stream and head leader music matching of audio data to determine the effective time range of a news program in a file; determining an audio mute point, an anchorman frame and the emerging time of a caption frame within the effective time range, and carrying out comprehensive analysis processing to determine the division time point of news items; and identifying video caption information, associating the caption information with a division result, and taking the caption information after association as cataloging semantic information. The system comprises a bar removing module and an educing module connected with a news video bar-removing result database as well as a browse module, a play module and a correction module connected in parallel between a client and the news video bar-removing result database. The method and the system solve the problems of news automatic bar removing and news item automatic semantic information labeling and realize automatic cataloging of news programs, thereby having the advantages of high efficiency and low cost.

Description

technical field [0001] The invention belongs to the field of video structure analysis, more precisely, relates to news video structure technology. Background technique [0002] Video structuring is to obtain structural information such as shots and scenes when the video is shot, and use this structured information to create some indexes for the video to facilitate the management and use of the video. A video program can be manually divided into multiple video segments that are relatively independent in content, and these video segments are marked for user indexing and use. However, the manual method takes a lot of time and labor costs, and is inefficient. Moreover, there are subjective inconsistencies in the manual annotation of videos. For the same video program, different annotations and users have different understandings. A certain inconvenience. [0003] Since it is not practical to manually structure the video, an automated method is used to process the video. Util...
