Problems solved by technology

[0003] The background update frequency of the existing video enrichment system is frequent, generally every 0.5S to 2S, and the method of frame-by-frame difference is adopted in the process of moving target extraction. resulting in time-consuming enrichment
In addition, most of the moving objects are sorted in a non-collision way, which leads to the situation that the concentration ratio is not high, and the storage volume of the concentrated video is too large

Abstract

The invention discloses an improved fast video summarization method and system and belongs to the digital image processing technology and computer vision technology field. According to the method and system of the invention, the summarization system is innovatively improved in that frequency-relatively slowed down background update, frame skip type target extraction and collision type target ordering are adopted, and therefore, higher-level requirements of today's society for the summarization system can be satisfied. The improved fast video summarization system not only has a moving target accurately locking ability of an original video summarization system, but also can perform summarization more quickly and greatly compress video time, and therefore, storage pressure can be reduced, and working time can be decreased.

Description

technical field [0001] The invention relates to the fields of digital image processing technology and computer vision technology, in particular to an improved fast video concentration method and system. Background technique [0002] With the rapid development of national economy and basic science, video analysis technology has made great progress. Among them, the video enrichment system, as an important implementation of video analysis technology, has been widely used in various fields of society. At present, the video concentration systems on the market generally have the problem of relatively low concentration efficiency and concentration ratio, which have not yet met the actual requirements of the project. [0003] The background update frequency of the existing video enrichment system is frequent, generally every 0.5S to 2S, and the method of frame-by-frame difference is adopted in the process of moving target extraction. This resulted in a time-consuming situation for...
