Abstract

The embodiment of the invention provides a method for detecting a target video fragment in a video. The method comprises the steps that one episode of a television drama is manually selected, and point location information of opening content and / or tail content in the episode of the television drama is marked; the manually-marked opening content and / or tail content in the episode of the televisiondrama is taken as the target video fragment; the image features of various key frames of various shots in the target video fragment are acquired by means of the methods of video shot detection, videoshot analysis and image feature extraction; the acquired image features are stored in a database to serve as a matching template; and for other episodes in the television drama, automatic detection on the repeated target video fragment in the television drama is achieved by adopting a template matching mode. According to the method, the workload of marking the target video fragment is reduced from the workload that all the episodes of the television drama need to be marked manually to the workload that only one episode of the television drama needs to be marked manually; and the manual workload can be reduced significantly.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method, device and electronic equipment for detecting a target video segment in a video. Background technique [0002] With the development of the file industry, the number of film and television dramas is increasing massively. Users can watch film and television dramas through mobile phones, TVs, computers and other devices. / or the end credits of the film and television drama. When a user watches a certain episode of a film and television drama, sometimes he needs to skip the title and / or the end of the title. In order to meet this requirement of the user, the premise is that the title and / or fragment of each episode of the film and television drama need to be detected. The principle of credits detection is the same as that of credits detection, and both the credits and credits are video clips in the episode. The detection of credits or credits is the detection of the tar...
