Problems solved by technology

[0003] In related technologies, the low-rank sparse matrix factorization algorithm is used to separate the foreground and the background in the surveillance video sequence. The prerequisite for using the low-rank sparse matrix factorization algorithm is that the background image of the surveillance video sequence does not change, so as to satisfy the low-rank condition , so once any tiny shaking of the surveillance camera occurs, the background of the video sequence will change, which will destroy the low-rank condition, resulting in the failure of the foreground and background separation of the video sequence

Abstract

The present disclosure provides a method and apparatus for separating the foreground and background of a video sequence. The method includes the following steps that: a first video sequence is obtained, wherein the first video sequence contains at least two video frames of image data; the image background of the first video sequence is corrected, so that a second video sequence of which the image background is static can be obtained; and a low-rank sparse matrix decomposition algorithm is adopted to separate the foreground and background of the second video sequence. With the method and apparatus provided by the technical schemes of the invention adopted, a video sequence of which the image background changes due to slight jigger of a camera can be corrected, so that the image background of the corrected video sequence can be static, and then, the low-rank sparse matrix decomposition algorithm can be adopted to separate the foreground and background of the video sequence, and the foreground and background of the video sequence can be obtained, and high robustness can be achieved.

Description

technical field [0001] The present disclosure relates to the field of image processing, in particular to a method and device for separating foreground and background of a video sequence. Background technique [0002] As a means of security, video surveillance is more and more widely used in today's life, from corporate shopping malls, to public places on the road, to ordinary people's homes are installed cameras for monitoring. Since the video images in video surveillance are static images most of the time, it has become a relatively common demand for users to separate moving objects such as people from surveillance videos for viewing. [0003] In related technologies, the low-rank sparse matrix factorization algorithm is used to separate the foreground and the background in the surveillance video sequence. The prerequisite for using the low-rank sparse matrix factorization algorithm is that the background image of the surveillance video sequence does not change, so as to sa...
