Video abstraction extraction method based on story plots

Abstract

The invention discloses a video abstraction extraction method based on story plots. The method comprises the following steps of conducting key frame, shot and scene detection on original video; detecting splendid scenes from the scene of the video story plots; selecting abstraction fragments from the splendid scenes according to actual situation, jointing according to timing sequences and generating the abstraction of the original video. The video abstraction extraction method further screens the splendid scenes according to evolution strength between the scenes, rejects alternative abstraction fragments which cannot express useful information due to short duration, and adjust the alternative abstraction fragments according to integrity of sentences. The method selects appropriate abstraction fragments to generate video abstraction according to development relationship of the story plots, meets logical thinking of people and is favorable for guaranteeing integrity of movie contents.

Description

technical field [0001] The invention relates to a method for extracting video summaries, in particular to a method for extracting video summaries based on story plots, and belongs to the technical field of image processing. Background technique [0002] As more and more video material is available on the web, on personal computers and digital devices, the desire to organize and manage this massive amount of data in an efficient and practical way is growing. Among these methods, the film summary method can not only obtain a simple description of the plot development of the original film material, but also help the audience to capture the theme of the film before watching the whole film. Therefore, the purpose of the movie summary is to select appropriate segments to form a movie summary according to the development of the storyline. However, how to reasonably select movie clips and effectively integrate them into summaries is still an issue for further research. [0003] Af...
