Embodiment Construction

[0026] The present invention will be further described below in combination with specific embodiments.

[0027] A method for video feature description and deduplication retrieval processing, specifically comprising the following steps:

[0028] (1) Video feature description: For any video, define a feature, and transform based on this to obtain multiple features;

[0029] The specific method of video feature description is as follows:

[0030] (11) For any video, number its video frame, the first frame is numbered 1, add 1 frame by frame, and its total frame number is recorded as N;

[0031] (12) Carry out scene detection to video, the video frame number of each scene switching is recorded; Concrete scene detection can adopt key frame detection algorithm etc., and detection algorithm does not do preset;

[0032] (13) Assuming that the detection is n segments of scenes, a video frame sequence S is formed after detection 1 , S 2 , S 3 ,…,S n , where S i The sequence numbe...

Abstract

The invention discloses a video feature description and deduplication retrieval processing method. The method specifically comprises the following steps: (1) video feature description: defining a feature for any video, and performing transformation based on the feature to obtain a plurality of features; and (2) duplicate removal retrieval processing: defining similar conditions of the two videos,performing feature extraction in the step (1) on the to-be-retrieved videos, and then performing quick arrangement according to the conditions. The beneficial effects of the invention are that: the method is suitable for large-scale production; according to the method, corresponding videos are described through defining a plurality of video features, then conditions similar to the videos are defined according to the video features, finally, the videos to be detected are subjected to video processing to obtain the corresponding video features, duplicate detection processing is carried out according to the video features, rapid arrangement of the videos is achieved through the design, and manpower expenditure is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video feature description and deduplication retrieval processing method. Background technique [0002] During the dissemination and processing of videos in different channels, such as transcoding with different resolutions and different bit rates, adding black borders, subtitles, and logos, etc. are often performed. Videos of the same film from different content providers may have the above-mentioned differences. [0003] The content introduction party often imports a large amount of video content from different content providers, and such content can reach tens of thousands. The content provided by the content provider will include descriptions such as title, file size, and duration. However, the titles of the same film provided by different content providers often have inconsistencies, such as Chinese and English problems, capitalization and other different...
