Active video enrichment device and method

Abstract

The invention discloses a device and method for active video concentration. According to the technical scheme, an input video is analyzed, a video structured description file is generated, and a relevant database is built; searching is carried out, and searching results are sequenced according to relevancy; an abstract video is generated according to the searching results. The video concentration process is rearrangement (time displacement) and compact piling up of target tracks, moving objects which appear in different time periods are translated to the same time period, and a transparent mapping mode is used for ensuring that overlapped areas of a plurality of targets are visible respectively. The original timestamp and the foreground rectangle of each target in the abstract video is labeled, a video indexing function is achieved, and corresponding original video clips are skipped to by clicking moving targets. The active video concentration scheme can be used for removing redundant target tracks and showing needed information of users, and the investigation efficiency based on videos is improved.

Description

Technical field [0001] The present invention relates to a video processing technology, in particular to a technology of video condensing (that is, generating video abstracts). Background technique [0002] In the field of social public security, video surveillance systems have become an important part of maintaining public order and strengthening social management. However, video recording has the characteristics of large amount of stored data and long storage time. The traditional method of finding clues and obtaining evidence through recording is to consume a lot of manpower, material resources and time, and the efficiency is extremely low, so that the best time to solve the case is missed. [0003] Video summary is a simple summary of the video content. In an automatic or semi-automatic way, the moving targets are first extracted through moving target analysis, and then the motion trajectory of each target is analyzed, and different targets are reorganized and spliced ​​into a c...

Problems solved by technology

[0007] In view of the above-mentioned prior art, the purpose of the present invention is to provide an active video enrichment solution, which is used to solve the problem that the existing video summarization method cannot meet the user's demand for specifying a specific target to generate a summary video, and the summary video generated by the traditional technology The problem of long duration and not compact movement
