Problems solved by technology

The input-output compression ratio of this method is very large, but it will form obvious splicing boundaries in the resulting video
This method loses both the dynamic information of the video and the context of the event

Embodiment Construction

[0088] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0089] figure 1 is a flow chart of a method for video concentration provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0090] Step 101: Perform modeling analysis on each frame of the original video image to determine the location of the foreground and background regions.

[0091] Embodiments of the present invention preferably use a mixed Gaussian model algorithm combining image color and gradient to model and analyze each frame of the original video image. After obtaining the background model, the embodiments of the present invention preferably use the background segmentation method and the minimum cut algorithm to obtain a smooth and ...

Abstract

The invention provides a method and system for video enrichment. The method comprises the steps that modeling analysis is carried out on each frame of image in an original video image, and the regional positions of a foreground and background are judged; a binary image is built; each object in the foreground is tracked to obtain an event body; the event body and event body information are stored in a foreground image database; the event body stored in the event body database is divided into event pieces according to preset time intervals, and feature information of the event pieces is obtained; cluster classification is carried out on the event pieces; video enrichment display is carried out; background images are sampled. According to the method and system for video enrichment, event bodies are extracted from a monitoring video automatically, classification and searching are carried out automatically for enrichment display, and therefore video enrichment is achieved, storage space and time needed for watching the video are saved, similar event bodies can be quickly searched out, and browsing and storage of monitoring videos are greatly facilitated.

Description

technical field [0001] The invention relates to the technical fields of computers and monitoring, in particular to a method and system for video concentration. Background technique [0002] With the continuous development of computer technology, the continuous improvement of processor speed, and the continuous improvement of network and other basic settings, more and more video surveillance systems are used in the daily management of cities. The accompanying huge amount of surveillance video is Subsequent video storage and viewing have brought difficulties. In order to ensure the stable operation and function of the huge monitoring system, let the monitoring system better understand the video content, and make the monitoring system serve people more intelligently, as a software solution for large-scale video monitoring systems, intelligent monitoring systems based on computer vision have been developed in recent years. to become one of the hot topics in the computer field. ...
