Embodiment 1

[0044] As shown in Figure 1, it is a flow chart of a video concentration method provided by an embodiment of the present invention, the method includes:

[0045] S102. Moving object detection and extraction: perform background modeling analysis on the video frame, segment the foreground object and background image of each frame, extract the moving object trajectory of each object, and store the object sequence and background image.

[0046] Specifically, this step S102 further includes:

[0047] (1) Input the video to be concentrated.

[0048] Specifically, in this step, the video to be processed is obtained, the video with different codes is decoded, and each frame is decoded into RGB color data.

[0049] (2) Perform background update, target detection, and target tracking on the video.

[0050] Specifically, the background update adopts a mixture of Gaussian models. The model is specifically: the mixed Gaussian model uses K (generally 3 to 5) Gaussian models to characteri...

Abstract

The invention discloses a video concentration method and a video concentration system, and belongs to the technical field of video processing. The method comprises the following steps that video frames are subjected to background modeling analysis, foreground targets and background images of each frame are divided, the moving target track of each target is extracted, in addition, the target sequence and background images are stored, the target sequence of the moving target track are subjected to optimized ranking, a new frame number sequence is generated and stored, according to a pixel merging algorithm, the foreground targets and the background images are subjected to seamless merging, the stored new frame number sequence and the stored background images are read, and a compressed video is generated. When the method and the system provided by the embodiment of the invention are adopted, the length of the compressed video is shortened, in addition, the moving object information in the video is retained as far as possible, the collision among multiple targets can be effectively prevented, and better visual effects are realized.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video concentration method and system. Background technique [0002] In recent years, with the rapid development of smart cities and safe cities, tens of thousands of surveillance cameras have been installed in public activities and gathering places such as parks, stadiums, large squares, schools, hospitals, commercial streets, and residential quarters. Multimedia, traffic video And security video data has grown explosively, and it is quite difficult to manage and analyze these videos. The traditional original browsing method often needs a lot of manpower and time, which is far from meeting people's needs for video information access and query. There is an urgent need for a fast and convenient method and system for browsing and viewing videos with good visual effects. Therefore, video enrichment technology emerges as the times require. [0003] Multi-objectiv...
