Embodiment Construction

[0022] When extracting and indexing scenes of movie videos, the present invention introduces the script and subtitle information corresponding to the video, so as to achieve a high-precision video scene extraction effect, and can automatically match the extracted scene video clips The corresponding text information in the script is used as its index, so as to avoid manual labeling. The script is the basis for the filming and production of film and television works, and it is actually the semantic information of the video (sequential images). The script of a film work generally consists of multiple scenes, and each scene in the script generally includes the following information: location, time, description of interior and exterior scenes, scene description, dialogue, etc. The dialogue in the script is actually the subtitles of the movie. At present, for high-definition DVD movies, the subtitles are generally released together with the video files in the form of plug-in files,...

Abstract

The invention relates to extraction method and index establishment method of movie video scene clips. The extraction method comprises the following steps: (1) obtaining the subtitle information of a movie video, including the text content of the subtitle and the appearing and disappearing time of the subtitle; (2) extracting the structural information of each scene from the script text of the movie video, including dialogues; (3) matching the dialogue information with the text content of the subtitle and obtaining the beginning and ending time of scenes in the video according to the appearingand disappearing time of the matched subtitle; (4) segmenting the movie video according to the final beginning and ending time of scenes in the video, which is obtained in step (3), to obtain the video segments of all scenes. In the index establishment method, the structural information obtained from the step (2) is used for establishing the index of the extracted video segments on the basis of the steps from (1) to (4). The invention has the advantages of low time consumption, high precision, and the like.

Description

technical field [0001] The present invention relates to the technical field of video indexing and searching, and in particular, the present invention relates to a method for extracting scene segments and establishing indexes for movie videos. Background technique [0002] Advances in the manufacture of inexpensive mass storage devices, higher network data transfer rates, and continued improvements in efficient video compression techniques have enabled the widespread dissemination and use of digital video. Video provides a large amount of information for multimedia system users, and it is also a data source for many application systems, such as digital libraries, digital publishing, digital entertainment, digital broadcasting, and distance education. At present, network services based on video information are in a period of rapid development. However, fetching specific video clips efficiently is currently still a very challenging problem compared with mature text information...
