Embodiment Construction

[0022] When performing scene extraction and indexing on movie videos, the present invention introduces two aspects of information corresponding to the video script and subtitles, achieving a higher-precision video scene extraction effect, and can automatically match the extracted scene video fragments. The corresponding text information in the script is used as its index, thus avoiding manual labeling. The script is the basis for the filming and production of film and television works, and is actually the semantic information of the video (continuous image). The script of a movie work is generally composed of multiple scenes. Each scene in the script generally contains the following information: location, time, interior and exterior description, scene description, dialogue and other content. The dialogue in the script is actually the subtitle of the movie. At present, for high-definition DVD movies, the subtitles are generally released together with the video files in the form...

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 search. Specifically, the present invention relates to a method for extracting and indexing movie video scene segments. Background technique [0002] Advances in manufacturing technology of inexpensive mass storage devices, higher network data transmission rates, and continuous improvement of high-efficiency video compression technologies have enabled digital video to be widely spread and used. Video provides a large amount of information for users of multimedia systems. At the same time, it is also a data source for many application systems, such as digital libraries, digital publishing, digital entertainment, digital broadcasting, and distance education. Currently, network services based on video information are in a period of rapid development. However, compared with mature text information search, it is still a very challenging problem to efficiently obtain specific video clips....
