Problems solved by technology

(2) The disadvantage of local features is high dimensionality and large amount of data. Due to the large scale of the video database, the computational complexity requirements are very strict. If only local features are used, it is not feasible, so local features need to be clustered and linear coding, which can reduce the dimensionality of high-dimensional local features and retain more representative parts of local features

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0016] figure 1 It is a flow chart of the method for detecting repeated videos in the present invention, such as figure 1 As shown, the method includes the following steps:

[0017] Step S1, frame sampling is performed on all videos in the database, and key frames of each video are extracted, so as to obtain key information of the corresponding video and reduce computational complexity;

[0018] The key frames of the video refer to certain frames that can represent the main information of the video. The extraction of key frames usually adopts the method of uniform sampling, and the sampling rate is two frames per second.

[0019] The function of video key frame extraction is to shorten the calculation time of video fea...

Abstract

The invention discloses a method for detecting repeated video. The method comprises the following steps of performing frame sampling on all video in a database, and extracting a keyframe of each video to acquire key information of corresponding video; respectively analyzing local features and global features of the extracted video keyframes to obtain local analysis features and global analysis features; fusing the local analysis features and the global analysis features to obtain a video-to-robustness index feature for detecting video repeatability; detecting the repeated video for video to be detected by using the index feature. By the method, the repeated video can be quickly and efficiently detected.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method for detecting repeated videos. Background technique [0002] With the development of science and technology, more and more technological products have entered people's work and life. The popularity of computers, cameras, handheld DVs, digital video recorders, mobile phones and other equipment has made digital video an indispensable part of work and life. Digital video has become the new mainstream of information dissemination. It contains more information than text, images, and audio, and has a wide variety of resources, including user-generated content (UGC), authorized film and television dramas, and surveillance videos. At the same time, the development of network technology has enabled the widespread dissemination of digital video, and people perform operations such as video upload, video download, video editing, and video viewing through the Internet....
