Embodiment Construction

[0051] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.

[0052] The video content visual analysis method based on the map metaphor of the present invention, its flow is as follows figure 1 As shown, first, according to the original video content, the key content is artificially extracted for structural processing, and the data of the corresponding structure is organized; then the processed data is processed by the layout algorithm to obtain the basic layout of the video map, and then the data is processed according to the map metaphor system The mapping rules of video content and content association are mapped to the video map to generate a video map visualization system, and finally the sketch interactive interface and other related functions such as statistical analysis and query path are real...

Abstract

The present invention relates to a video content visual analysis method based on a map metaphor, and belongs to the technical field of computer application. The method comprises: firstly, performing structuring processing according to an original video content to obtain data in a corresponding structure, and establishing a semantic association relationship between a map and a target video; then, performing layout algorithm processing on the processed data, so as to obtain a basic layout of a visualization system, and according to a mapping rule of a map metaphor system, mapping a video content and association onto a video map to generate the video map visualization system; and then implementing a draft interactive interface and other related functions such as counting, analyzing and querying paths. Compared with the prior art, the video map constructed by the method provided by the present invention meets cognitive habits of people, and based on an advantage of map expression, excellently presents a complex semantic relationship between the videos, and meanwhile breaks a conventional single linear passively browsing mode, and helps users browse the videos better.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to a visual analysis method for video content based on map metaphors. Background technique [0002] With the popularization of digital equipment and the development of Internet technology, the number of video resources has grown massively. People are no longer satisfied with the traditional single linear video information utilization method, and have put forward higher requirements for effective video information retrieval, fast access to video main content, and efficient video browsing. The rapid growth of video data has become one of the most important ways of obtaining information in people's lives. How to quickly acquire video information, efficiently interact and effectively use video information has great application value. At present, in contrast to the rapid growth of video applications, there has not been a fundamental change in the way of intera...
