Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] like figure 1As shown, the flow chart of the subtitle information-based automatic video segmentation and labeling method proposed by the present invention. The subtitle information-based video segmentation and labeling system of the present invention can be divided into two parts: a subtitle information extraction system and a video segmentation and labeling system. The subtitle information extraction system extracts the subtitle information in the video, obtains the appearance time and disappearance time of the subtitle, and uses character recognition technology to identify the subtitle to obtain text information. In the video segmentation and labeling system, the time point of video segmentation is calculated by using the time information of subtitle information. Since the first frame of video in the video segmentation time interval is not a k...

Abstract

The invention discloses an automatic video segmentation and annotation method and system based on caption information. The method is characterized in that caption information in a video is extracted and fragmentation processing is performed on the video based on the caption information. The method comprises the following steps: (1) using video caption information extraction technology, extracting caption information from the video, wherein caption information specifically contents time information and text information of caption; and (2) determining all segmentation time intervals of the video to be segmented according to the time of occurrence of the caption and the time of occurrence of the next caption, and segmenting the video based on the segmentation time intervals by using video transcoding technology, and performing annotation on the video by using the text information in the caption. The invention provides the automatic video segmentation and annotation method and system based on caption information through combination of the caption extraction technology and the video segmentation technology, realizing automatic segmentation and annotation of video contents, and the method and the system can be used in the technical fields of fragmentation processing of video contents, cataloguing and searching of video contents and the like.

Description

technical field [0001] The invention relates to technical fields that can be used for fragmentation processing of video content, cataloging and retrieval of video content, and in particular to a method and system for automatic video segmentation and labeling based on subtitle information. Background technique [0002] The most obvious feature of the Internet age is the fragmentation of communication. Today, with the advent of the community-based era, fragmented information dissemination led by Weibo has gradually become popular, and "short and concise" has increasingly become the essence of content dissemination and sharing. [0003] In the video industry, technological innovations aimed at sharing, cataloging and retrieval are bringing video dissemination into the era of fragmentation in the same way. The text information in the video is undoubtedly an important clue to realize these demands. [0004] Traditional video segmentation is done manually and requires a lot of m...
