Movie action scene detection method based on story line development model analysis

Abstract

The invention discloses a movie action scene testing method based on analysis of a story line development model, which comprises the steps that: a video is carried out with the operation of pretreatment; the scene length of each scene is calculated; the average action intensity of the scenes is calculated; a movie editing factor is calculated by utilizing the scene length and the average action intensity of the scenes; the short-term audio energy of each audio frame and the average audio energy of the scenes are calculated; the average action dispersity of the scenes is calculated; a human perception factor is calculated by utilizing the average audio energy of the scenes and the average action dispersity of the scenes; according to the movie editing factor and the human perception factor, the story line development model is established and a story line development flow graph is generated according to the time order; action scenes in a movie are tested according to the story line development model. The testing method has the advantages that the story line development model is established by taking two viewpoints of the movie editing method and human perception into account to consider visual and auditory factors so as to simulate story line development and change, thereby realizing the accurate test of the action scenes in the movie.

Description

technical field [0001] The invention relates to the field of video analysis and detection, in particular to a movie action scene detection method based on story plot development model analysis. Background technique [0002] With the rapid development of today's digital media and networks, people can enjoy various multimedia information at home without going out. Today the world's film industry is an active force in video production, with approximately 4,500 new films appearing each year. Therefore, how to effectively analyze, manage, query and retrieve these massive amounts of information has become an urgent problem to be solved. [0003] In movies, because action scenes usually have strong dramatic conflicts and intense visual effects, they are the focus of movie editing and the most interesting scenes for audiences. To detect action scenes in movies, we need the method of movie content analysis. Currently, there are two main methods for analyzing movie content: [000...
