AI Technical Summary

Problems solved by technology

However, it takes a lot of computing time to generate the summary image sequence in this way to obtain the background image and the foreground object image sequence
In addition, limited by the bottleneck of the current image analysis capabilities, the obtained image sequence of foreground objects cannot guarantee to extract the complete object image, and even some foreground information is omitted, resulting in the inability to present all the complete object information in the video

Abstract

A method and system for generating a video synopsis from compressed video images is disclosed, wherein the compressed video images are generated by dividing each image of the original video into a plurality of macroblocks. By analyzing and utilizing characteristics of video compression information to determine the importance of each of the macroblocks, the distribution of the important macroblocks in time and space can be obtained, and a video synopsis of a specified length can be synthesized by arranging the important macroblocks in a particular temporal and spatial order.

Description

technical field [0001] The invention relates to a method and a system for outputting a video time-lapse summary, in particular to a method and a system for outputting a video time-lapse summary for fixed monitoring compressed video data. Background technique [0002] Generally, when inspecting surveillance video, most of them use the method of manual quick playback to quickly inspect the relevant surveillance video. It will be a very labor-intensive and time-consuming task to inspect the surveillance video in this way, but how to effectively and quickly inspect the desired Viewing video data, so that users can reduce manpower and time consumption, and effectively and quickly obtain the required video segment data, will be an urgently needed function for monitoring video playback equipment. [0003] In the prior art, methods such as video abstract, video summary, and video indexing provide means to quickly search for important image information in surveillance videos, such as...
