Embodiment

[0050] The static surveillance video summarization method based on video moving target detection and tracking in the present invention comprises the following steps:

[0051] (1) Establish a mixed Gaussian background model to detect video moving targets;

[0052] (2) Kalman filter algorithm to track multiple moving targets and save the tracking data;

[0053] (3) segment the original video into multiple small segments according to the tracking data;

[0054] (4) Extract the key frame of each video clip and add the motion track at the same time.

[0055] The step of moving target detection in step (1) comprises:

[0056] (A) Establish a mixed Gaussian background model to extract the background image and initially obtain the foreground image;

Abstract

The invention discloses a static surveillance video abstraction method based on video moving target detection and tracing, which comprises the following steps: (1) establishing a mixed Gaussian background model detection video moving target; (2) using the kalman filtering algorithm to trace multiple moving targets and store the trace data; (3) dividing the original video into multiple segments according to the trace data; and (4)extracting the key frame of each video segment and adding the motion trail. The method is simple to realize and has better performance.

Description

technical field [0001] The invention belongs to the field of intelligent video monitoring, in particular to an intelligent monitoring video summary method, in particular to a static monitoring video summary method based on video moving target detection and tracking. Background technique [0002] With the development of digital video processing technology and the improvement of social security awareness, surveillance equipment is widely used in all walks of life, which generates a large amount of surveillance video data, making video storage, retrieval and browsing operations complicated and time-consuming . In order to quickly browse and efficiently utilize these monitoring data, video summarization technology is particularly important. [0003] Video summarization technology is to extract the main information in the video through the analysis of the video content and structure, and combine them in a certain way into a short video or video image frame that can fully express...
