| 摘 要： | 提出一种基于对称帧间差分与背景减除相结合的运动目标检测和自适应背景更新方法.该方法首先建立背景模型,采用帧间差分法将当前帧图像分别与其相邻两帧图像相比较得到运动目标前景部分,并将三帧中变化率小于某一阈值的像素点以一定的更新率实时更新到背景模型中.同时,采用背景减除法对所建立的背景模型进行前景提取,将两种方法所获得的前景图像进行融合,再通过数学形态学运算去除噪声及小面积非人体运动部分,最终得到完整可靠的运动人体二值图像.实验结果表明该方法准确高效,能很好地克服光线的影响,提高监控系统的稳定性.

| Abstract: | In this paper,a new method of moving-people detection based on fusion of coterminous frames differencing and background subtraction is proposed.Firstly,the method constructs the auto-adapted background model and updating real-time through temporal difference to the video stream,and simultaneous adapting background subtraction extract foreground region from the established background model.Then the method integration the two foreground regions for people identification,together with utilization of the median... |
