Abstract

The invention discloses a method and a device for generating a video summary, and relates to the technical field of video processing. The method comprises the steps of confirming the classification of a video through textual characteristics, audio information and video characteristics in the video, carrying out corresponding video scene detection for the video according to the classification of the video, and extracting key frames in a video scene to generate the video scene summary. The scheme with multi-media content analyses comprises key frame detection, lens boundary detection, image similarity analyses, face detection and identification, text search, news story segmentation, sports key scene analyses and the like. Automatic generation of the functions, such as a video browsing function and a video summarizing and rapid previewing function, of interactive television content is achieved. The functions generated by the interactive television content are automatically achieved based on multi-media content analysis techniques. Time-wasting and expensive labor editing processes can be avoided.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method and device for generating a video summary. Background technique [0002] At present, the mainstream of TV content is still broadcast, passive, and linear sequential viewing experience. Interactive TV, on the other hand, is about creating proactive, customized, two-way communicative TV content. Although the content of interactive television can be traced back to the 1920s, it is still not very mature until now. Currently, the content and form of interactive TV are very limited, such as online video-on-demand, time-shifted TV (allowing users to record programs and return to them), and DVD chapter browsing. Interactive TV mainly relies on manual editing, production and maintenance. The main disadvantage of manual production and editing of interactive TV program content is that the speed is very slow and the labor is very expensive. [0003] With the deve...
