Problems solved by technology

In the above applications, two basic problems to be solved are: (1) How to measure the similarity between two news videos? (2) How to cluster the news reports of the same event together?
This method requires the user to have a query example, but when the user does not have a query example, this method cannot retrieve
In fact, there is no retrieval of query examples, such as the query "what is the important news today?", "play a summary of today's important news", etc., that is, the method of detecting and summarizing important news events has not yet been seen. Jobs, Literature and Patents

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] figure 1 Listed the schematic flow sheet of each step method of the present invention, comprises the following steps:

[0042] 1. Shot boundary detection

[0043] First, use the spatio-temporal slice algorithm (spatio-temporal slice) for shot boundary detection, and divide each news event in the news video library into shots. For a detailed description of the spatio-temporal slice algorithm, please refer to the document "Video Partitioning by Temporal Slice Coherency" [C.W. Ngo, T.C. Pong, and R.T. Chin, IEEE Transactions on Circuits and Systems for Video Technology, Vol.11, No.8, pp.941-953, August, 2001].

[0044] In addition to the spatio-temporal slicing algorithm used in the present invention, there are many methods for segmenting shots, for example, subtraction of adjacent frames, difference of histograms of adjacent fr...

Abstract

The disclosed method includes steps: first, using method for measuring degree of similarity of video events to calculate degree of similarity of all news events in news video library collected from multiple TV station and TV channels; then, using cluster-algorithm to segment different reports for same news event into clusters; finally, base on number of member in each event cluster, broadcast channel and time, the method detects important news event automatically, and forms headlines at time specified by user according to high and low importance. Comparing with existing method, which prepares headlines based on a period of video mainly, the invention is able to detect important news and form relevant headlines. Practice result expresses the said comparison.

Description

technical field [0001] The invention belongs to the technical field of video analysis and retrieval, and in particular relates to a method for detecting and summarizing important news events. Background technique [0002] With the accumulation of television programs, the increase of online digital videos, and a large number of multimedia applications such as digital libraries, video-on-demand, and distance learning, how to effectively organize massive video databases to facilitate people's quick browsing and retrieval has always been an issue in the computer field. hot issues. Among various types of video, news video is arguably the most important form of video. It not only has important practical use value, but also has precious historical collection value, which is indispensable for government, TV station, news media and ordinary users. At present, in addition to the existing massive news video library, there are a large number of news reports every day in the world, and...
