摘　　要：针对Vi Be算法存在的不能有效去除背景噪声以及鬼影现象,提出一种结合帧差法和Vi Be算法的改进算法。首先利用帧差法提取出运动目标的轮廓,然后根据得到的轮廓粗提取运动目标区域,最后在得到的运动目标区域基础上分类进行Vi Be算法更新背景并分割出完整的运动目标。实验结果表明,此算法能够有效抑制噪声以及鬼影造成的影响,在速度方面也比原算法有所提高。To solve the problem that traditional Vi Be algorithm can not effectively remove the influence of background noise and ghost,an improved algorithm based on Vi Be and frame-difference algorithm was proposed. Firstly,the frame-difference algorithm was used to extract the contour of the moving object. Secondly,the contour was used to get the general area of the moving object.Lastly,the object could be perfectly segmented from region after updating background using Vi Be algorithm on classification based on the general area. Experiments show that,this algorithm can suppress the influence of noises and ghost effectively,and its processing speed is better than the traditional Vi Be algorithm.
