Abstract

The invention provides a video matching method and a system. The method comprises the following steps: a template video and a to-be-matched video are acquired, and adaptive scene segmentation is carried out on the template video and the to-be-matched video; a template video scene collection and a to-be-matched video scene collection are obtained; coarse matching is carried out according to the edit distance between the template video scene collection and the to-be-matched video scene collection, and a coarse matching position is obtained; according to the template video, the to-be-matched video and the coarse matching position, precise matching is carried out, and a precise matching position is obtained; and according to the precise matching position, a video matching result is outputted. According to the above video matching method and the system, adaptability and accuracy of video matching can be improved, the video matching efficiency is improved, and the edge position of an ad video can be precisely positioned.

Description

technical field [0001] The invention relates to multimedia technology, in particular to a video matching method and system. Background technique [0002] In common TV videos, such as TV dramas, entertainment programs, and variety shows, interstitial advertisements are often used to obtain revenue or conduct publicity. [0003] It is often difficult to supervise the interstitial advertisements. In the traditional technology, the advertisement video played in the TV video is detected by obtaining the longest common substring of the advertisement video and the TV video. However, the detection is often not accurate enough for the TV video whose scene changes are not obvious. . Contents of the invention [0004] Based on this, it is necessary to provide a video matching method that can improve the detection accuracy for the problem of inaccurate detection of advertising videos in TV videos. [0005] In addition, it is also necessary to provide a video matching system that can...
