Problems solved by technology

However, traditional keyframe-based summary video generation methods using frame sampling cannot fully represent the motion trajectory of each object, resulting in the loss of a large amount of useful video information.

Embodiment 2

[0106] The trajectory of the moving object is based on the detection identification and tracking extraction of the previous moving target, where the moving target detection recognition phase is a target detection recognition after the Gaussian background reconstruction, one classifier will identify an object. It is followed by a trajectory combination of an annealing annealed annealing, making the entire trajectory of all objects minimal, will eventually get people and trails of people and traversal procedures and vehicle abstracts.

[0107]Traditional monitoring summary video When selected a summary video background, a Gaussian model is selected for the original video. However, in the actual monitoring video scene, the background of the original video is changed, for example, there is a stationary vehicle in the current video frame, the still object is treated as a background, with the moving vehicle, the stationary vehicle happens Sports, it is no longer a background. If the bac...

Abstract

The present invention relates to a generation system and method of a summary video, the system includes a detection, identification, tracking and extraction module, a combination optimization module, a video frame background module, a track background pasting module, and a summary video module; the detection, identification, tracking and extraction module detects and identifies moving target areas The moving object in the detection and identification is tracked and the motion track is extracted; the combined optimization module combines and optimizes the extracted motion track; the video frame background module dynamically updates the video background in the moving target area; the track background paste module Match and paste the moving object and the updated video background according to the combined and optimized motion trajectory to generate a summary video frame; the summary video module generates a summary video according to the summary video frame. Compared with the prior art, the summary video of the present invention is shorter than the original video, retains the information of most moving objects in the original video, is convenient for quick browsing, and has high processing efficiency.

Description

Technical field [0001] The present invention relates to the field of video image processing, and more particularly to a generating system and method for a summary video. Background technique [0002] With the rapid development of monitoring technology and network technology, HD network surveillance cameras are widely used in various industries. These high-definition cameras have worked all day, producing a massive monitoring video data, but because the limitations of monitoring human resources and time resources often lead to some massive video data never been processed. How to quickly and completely browse for a long time monitoring video has become a problem that the monitoring industry needs to be solved; the summary video is an important means of solving "massive video data processing". However, traditional keyframe-based summary video generation methods use frame samples that cannot be completely indicated by the movement trajectory of each object, resulting in a lot of usef...
