Embodiment Construction

[0026] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0027] The invention proposes a method for quick statistics of long video content and automatic review of suspicious objects. The purpose of this invention is to figure 1 In the case of partially copied video clips shown, multiple target videos are quickly located from the long video, and based on the positioning results, quick statistics of the target content and automatic target review are performed. figure 1 The given example of partially copied video clips shows that the long video referred to in the present invention contains multiple areas similar to the target video, and each area may be different from the matching image sequence object in t...

Abstract

The invention discloses a method for quickly counting and automatically examining and verifying target contents of long video. The method includes steps of extracting key frame sequences of the long video and target video; extracting local binary-pattern histogram features and spatial gray sequence features of the key frame sequences; quickly searching the target video in the sequence of the long video; roughly positioning the target video; precisely positioning the target video in the sequence of the long video by a temporal-spatial constraint maximal connected region process; judging whether positioning for the target video in the long video is completed or not; counting the contents of the long video and automatically examining and verifying suspicious targets according to positioning results. The method has the advantages that by the method, the large-scale long video can be automatically processed, the contents of the long video can be quickly counted, and contents of the suspicious targets can be automatically examined and verified.

Description

technical field [0001] The invention relates to the technical field of multimedia video processing, in particular to a method for fast statistics and automatic review of target content in long videos, which can be applied to statistics and supervision of radio and television video advertisements. Background technique [0002] With the rapid development of computer, multimedia and other technologies, the scale of video is increasing geometrically. While enjoying video content, people also face various troubles caused by the rapid expansion of video scale. For example: Advertising video, as a special form of video application, exists in large numbers in various TV stations and video-on-demand websites. By broadcasting advertisements, advertisers promote their products, and TV stations or video websites also obtain huge profits. However, However, due to the huge scale of videos, it is extremely difficult to effectively count and supervise advertising content. [0003] In the ...
