Abstract

In order to solve the problem of small relevance between target video clip extraction and user interestingness, the invention provides a target video clip extraction method, which comprises the following steps of: obtaining target scene classification information and target person information; identifying a scene to obtain a scene classification wonderful degree score of each video clip; identifying the character to obtain a target character identification wonderful degree score of each video clip; generating a user option wonderful degree score according to the scene classification wonderfuldegree score and the target character identification wonderful degree score; according to the image difference, obtaining an image wonderful degree score of the video clip; according to the short-timeenergy value of the audio frame, acquiring an audio highlight score of each video clip; obtaining a content highlight score according to the image highlight score and the audio highlight score; obtaining a diversity score between the video clips according to the distance between the video clips; and according to an optimization objective function f(X)=[Sigma]i<XUScore(i)*w1+[Sigma]i<XCScore(i)*w2+[Sigma]i, j<XDScore(i, j)*w3, selecting a preset value Nsel video clips to form a target video clip set X, so that the value of f(X) is maximum.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a method for extracting a target video segment, an extracting device, a computer-readable medium and electronic equipment. Background technique [0002] With the rapid development of Internet technology and the popularity of mobile devices such as mobile phones, the cost of video production and dissemination is getting lower and lower, and a large number of videos are produced every day. When people are faced with massive videos, how to find the content they are interested in becomes a difficult problem. The traditional method of relying on manual browsing and screening of videos is high in cost and low in efficiency. With the explosive growth of videos, it even becomes unfeasible. In response to this problem, people have developed a video highlights extraction technology, which can automatically identify and extract highlights in videos, greatly reducing the...
