Embodiment Construction

[0087] The technical solutions of the video matching method and system will be described in detail below with reference to specific embodiments and drawings to make it clearer.

[0088] Such as figure 1 As shown, in one embodiment, a video matching method includes the following steps:

[0089] Step S110: Obtain a template video and a video to be matched.

[0090] In this embodiment, the template video and the video to be matched input by the user are obtained. The template video may be an advertisement video, the video to be matched may be a TV video containing one or more template videos, and the template video and the video to be matched may be frames The same rate and width and height are the same. If they are different, they can be made the same through video conversion to facilitate video matching. In addition, the time length and frame number of the template video and the video to be matched are obtained separately to facilitate recording of the video frame position.

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 present 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 shows, and variety shows, advertisements are often inserted to gain revenue or promote. [0003] It is often difficult to monitor interstitial advertisements. In traditional technology, the longest common substring of the advertisement video and the TV video is used to detect the advertisement video played in the TV video. However, the detection of the TV video with unobvious scene changes is often not accurate enough. . Summary of the invention [0004] Based on this, it is necessary to provide a video matching method that can improve the accuracy of detection in order to solve the problem of insufficient accuracy of detecting advertisement videos in TV videos. [0005] In addition, it is also necessary to provide a video matching system that can improve the accuracy of...
