Abstract

The present invention proposes an adaptive visual background extraction method, which includes the following steps: S1. Initialize the background model using pixels in several odd frames before the video sequence; S2. Traverse the current video frame information to calculate the current pixel S of the sample set and the current pixel w ×S h The sum of the average difference in the neighborhood, and judge the background complexity of the current pixel according to the sum of the average difference; S3. Get the adaptive segmentation threshold and adaptive update rate of the current pixel according to the obtained background complexity; S4. The detected results are post-processed. The invention has high detection precision and good effect; can eliminate the problem of ghost images in the detection; and has strong robustness for situations such as dynamic and complex backgrounds and illumination changes.

Description

technical field [0001] The invention relates to the field of moving target detection in intelligent video detection, in particular to an adaptive visual background extraction method and device. Background technique [0002] Due to the rapid development of the global economy in recent years, more and more people have poured into the city, resulting in the social security and traffic safety in the city becoming more and more complicated. From time to time in the city, something is lost or a vehicle collides, etc., which is very difficult for ordinary manpower to find the thief or the perpetrator. The birth of computer vision technology, especially the development of target extraction technology, provides the possibility for these situations to be monitored. Nowadays, many residential quarters, company buildings, roads, squares, and places such as banks and supermarkets are equipped with video surveillance systems for security, so as to ensure the safety of life and work, or p...
