Problems solved by technology

[0009] In general, the problem of video summary generation is very complicated. If there is no restriction on the environment, it is very difficult to realize a real-time, fast, stable and efficient summary generation system.
The research on abstract generation technology is relatively early. From the existing data, there are still many problems. There is no actual system to achieve stable real-time. Especially from the perspective of user satisfaction, the lack of satisfaction is still common in various methods. The problem

Embodiment Construction

[0120]In order to better illustrate the purpose and advantages of the present invention, five MTV videos (three Chinese, two European and American) with different lens rhythms are used as data sources below (the detailed information of each MTV is shown in Table 1 below), and the method of the present invention The implementation mode is described in further detail.

[0121] Table 1 Example data source information

[0122]

[0123] All the following tests are completed on the same computer, the specific configuration is: Intel dual-core CPU (main frequency 1.8G), 1G memory, WindowsXP SP3 operating system.

[0124] The purpose of static summarization is to represent the information of all lens groups in the video, so this paper uses the recall rate and precision rate of lens groups as the evaluation index of static summarization.

[0125] For dynamic summarization, this paper evaluates the system by giving the user satisfaction (User Satisfaction, US) under a series of spec...

Abstract

The invention relates to a generation method of a high-satisfaction video summary. Based on the characteristics of a video data structure, a shot cluster-based video summary system is designed and realized in the invention. The video summary system has the following main functions: coding, decoding and playing of various video files, shot boundary detection, key frame extraction, shot cluster, generation of both static video summary and user input time dynamic summary, and the like. The generation method is suitable for various application occasions, such as multimedia file management, video retrieval, and film and television database construction.

Description

technical field [0001] The invention relates to a method for generating a high-satisfaction video abstract, which belongs to the field of multimedia information processing, specifically, the field of video information processing. Background technique [0002] With the rapid increase of the number of digital video resources, it becomes very important to represent, understand and extract video structure to provide video content browsing and retrieval services. Among them, content-based video analysis technology is its main task. Content-based video analysis refers to the semantic analysis and understanding of video data containing images and sounds using computers. Its rapid development has produced many new research results and applications of related technologies. In these emerging research fields, there are some applications and researches on how to use the analysis of video content to reduce the cost of video storage, classification and indexing, and how to improve the e...
