Embodiment Construction

[0042] A method for generating video summaries that can solve multi-target collision and occlusion problems described in the present invention includes a background reconstruction module, a target detection module, a target tracking module, a target trajectory post-processing module, a target trajectory generation module, and a video summary generation module. The background reconstruction module uses an adaptive mixed Gaussian model to process the video image, judges whether it is a foreground or a background for each pixel, obtains the foreground image and the background image, and reconstructs the background model in real time; the target detection module uses the background The foreground image obtained by the reconstruction module detects all clumps that newly enter the scene, and then discards smaller clumps (which may be caused by noise) and clumps that overlap with the already tracked clumps, and through image boundary detection and motion Consistency detection is scree...

Abstract

The invention provides a video synopsis generation method capable of solving the multi-target collision and occlusion problem. The method comprises a background reconstruction module, a target detection module, a target tracking module, a target trajectory post-processing module, a target trajectory generation module and a video synopsis generation module. The method is an object-based dynamic video synopsis generation method; the method carries out intelligent analysis processing on surveillance videos, carries out detection and tracking on targets in a source video and extracts trajectory information of target positions and sizes and the like, and generates a concentrated video comprising all of the targets through trajectory combination and optimization; and the method can reduce video space redundancy and time redundancy.

Description

technical field [0001] The invention belongs to the technical field of video monitoring and image intelligent analysis, and relates to a method for generating video summaries that can solve the problems of multi-target collision and occlusion. Background technique [0002] As a widely used technical prevention method, video surveillance system plays an increasingly important role in the construction of comprehensive prevention and control system of urban social security. However, the ever-increasing number of cameras of all kinds are constantly recording day and night, so that the problem of "visibility" has been well solved. However, searching for massive video data is like finding a needle in a haystack. Clue finding has been unable to cope with video investigation in the era of big data. With the continuous expansion of the system scale, how to quickly and accurately browse and find clues in massive videos has become an urgent problem to be solved. [0003] As an import...
