Video-processing method and device

Abstract

The invention discloses a video-processing method and device, and belongs to the field of video signal processing. The method comprises the steps: marking a target region in a video picture according to preset conditions; Dividing a video of the target region into a plurality of segmented scenes according to a first preset algorithm; selecting a key frame of each segmented scene according to a preset rule; obtaining a moving target of each segmented scene according to a second preset algorithm, tracking the movement locus of each obtained moving target, and extracting each picture frame of the moving locus of each moving target; enabling each picture frame of the moving locus of each moving target in the target region to be overlapped on the key frame of the segmented scene corresponding to the moving locus of the corresponding moving target, and generating a video summary. The objective of the invention lies in providing the video-processing method and device, so as to effectively improves the monitoring efficiency of the conventional video monitoring technology.

Description

technical field [0001] The present invention relates to the field of video signal processing, and in particular, to a video processing method and device. Background technique [0002] Video surveillance has become a very important technical means in the field of modern social security, but the information redundancy of video surveillance and the inefficiency of finding interesting information also hinder the effective application of video intelligent surveillance technology. [0003] For example, the surveillance video involving a button may last for tens or even hundreds of hours, and the important scenes that are really useful for solving the case often only appear for a short time in the surveillance screen. If the original video is viewed manually, it is easy to miss these Important information is fleeting, leading to inefficiency. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a video processing method and device to effectively i...

[0002] Video surveillance has become a very important technical means in the field of modern social security, but the information redundancy of video surveillance and the inefficiency of searching for interesting information are also hindering the effective application of video intelligent surveillance technology.

[0003] For example, a surveillance video involving a button may last tens or even hundreds of hours, and the important scenes that are really useful to solve the case often appear only for a short time in the surveillance screen, which is very easy to miss if the original video is manually viewed Important information is fleeting, resulting in low efficiency
