After the analysis of advantages and disadvantages of moving object extraction algorithms in the case of still background , an algorithm for moving object extraction under the changing background is presented , which can effectively solve the problem of background difference between serial images 摘要分析了常用的静态背景下运动目标提取算法的优缺点,提出了一种基于背景匹配的运动目标提取的算法,有效地解决了帧间背景的微移问题。
