Abstract

The invention discloses a method for generating a video navigation system automatically, which comprises: cutting a video into a plurality of pictures by using a double-threshold picture cutting algorithm; extracting the key frames of the pictures by using a leading clustering algorithm; clustering the pictures by using the leading clustering algorithm to form a picture group; and creating a scene by using the picture group. The method improves the structuralization degree of the videos greatly, makes a hierarchical directory of the videos, and facilitates the video content capture and browsing of users. The method can make a DVD directory conveniently and provide support for video retrieval technology. Today, when videos have become part of people's life, the method has great applicationvalue and prospect.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a video structure analysis method and a video navigation system. Background technique [0002] With the development of computer technology and multimedia technology, personal computers and digital devices are becoming more and more common, and people watch and shoot more and more videos in their lives. The development of network communication technology has made it easy for videos to spread on the Internet, and some video portals have emerged as the times require, such as Youku and Tudou in China, and Youtube in foreign countries. Ordinary people can upload videos taken in their daily life to video sites for other users to watch. Digital video has become an indispensable part of people's learning and entertainment. [0003] Compared with text and images, video has the advantages of rich information, but also has the disadvantages of huge data volume and low degree...
