Spiral abstract generation method oriented to video content

Abstract

The invention belongs to the technical field of computer application, and specifically relates to a spiral abstract generation method oriented to video content. The method provided by the invention is implemented through a system comprising a preprocessing module, a layout module and a smooth transformation module, firstly, a video is treated by the preprocessing operations, such as shot segmentation, shot screening, key frame extraction, and region of interest extraction, to obtain the region of interest of the key frame, then, the ROI (Regions of Interest) are arranged on a spiral geometric structure through a spiral abstract layout algorithm, and then, the display region of the key frame is processed so as to obtain a new spiral abstract presentation form capable of effectively presenting the video content. The method provided by the invention can be used for presenting the video content in a spiral form, supporting the continuous display of the video content, keeping the linear timeliness of the video stream, improving the utilization rate of the screen space, and supporting the multi-point touch gesture and the continuous zooming mode to implement multi-scale video browsing, thereby improving the video content understanding efficiency and the video location efficiency of users.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to a video content-oriented spiral abstract generation method. Background technique [0002] As a media form with a large amount of information and strong expressive power, video has always been an important carrier for people to exchange information. Video data has shown explosive growth in recent years, occupying an increasingly important role in people's daily life. status. With the rapid development of hardware technology and network technology, more and more people choose to use computers to watch videos. According to the "2010 Research Report on Online Video Application of Internet Users in China", as of December 2010, the number of domestic online video users was 284 million, with a penetration rate of 62.1% among Internet users, and 45.4% of users had uploaded original video programs. The interaction needs of the majority of users for the presenta...
