摘 要: 为了从复杂环境中获取高质量背景图像,提出一种基于帧间差分和背景减除法相结合的背景提取算法,采用多层次自适应背景更新的策略,能够克服新增物体对背景的影响,并能及时消除由于背景物体移出而造成的鬼影。实验证明该算法对光线变化鲁棒性高、速度快、更新效果好。 To extract good background image from complex scenes,this paper proposes an algorithm of background extraction based on both frame-difference and background subtraction,and using multi-level adaptive background update strategy,it can avoid the effect of new objects to the background and eliminate the ghosts caused by the move-away of background objects.Experiment shows it is a practical method that is robust under lighting variations,fast in speed,satisfactory in updating performance.
