Method for video matching in video template library

Abstract

The invention discloses a method for video matching in a video template library. A video template and an index of all feature codes corresponding to appearance positions of the feature codes in the video template are stored in the video template library, wherein the video template is obtained by connecting the feature codes of key frames in a time sequence. The method includes the steps that a query video is segmented, the key frames are selected from all query video segments, and the feature codes are extracted from all the key frames; the feature codes of all the key frames of all the query video segments are extracted, and the video template where the feature codes appear is searched for according to the index of the feature codes in the video template library; video template segments corresponding to the query video segments are found out in the video template according to the positions of the key frames in the query video segments, and whether the query video segments and the video template segments have a matching relation is judged through comparison based on the feature codes; the corresponding appearance position of the video template in the query video is obtained according to the matching relation between the query video segments and the video template segments. The method for video matching in the video template library improves video matching speed and robustness.

Description

technical field [0001] The invention belongs to the field of video processing, in particular to a video matching method in a video template library. Background technique [0002] With the development of Internet and digital multimedia content, how to quickly and effectively retrieve video has important application value. Especially in the field of radio and television, there is a wide demand for highly robust large-scale template library indexing and fast matching technology. From the point of view of the radio and television regulatory department, through the detection of advertisements and programs, the broadcasting of advertisements and programs can be reviewed in a timely manner to check whether there are advertisements and programs broadcast in violation of regulations. For example, the State Administration of Radio, Film and Television's "Administrative Measures for the Broadcasting of Radio and Television Advertisements" stipulates that "the broadcast of radio and te...

Problems solved by technology

Obviously, to complete the above-mentioned video monitoring work, due to the large number of TV stations, more channels, and long broadcast time, it is obviously difficult to use manual real-time monitoring methods, so it is necessary to automatically monitor advertisements or TV programs.

[0003] The feature extraction process of the existing video template library matching technology is relatively complicated, the robustness is relatively poor, and it cannot support the requirements of fast matching of large-scale template libraries
