运用差分法将动态图像序列的背景重建，根据运动序列建立自适应背景-difference method using dynamic image sequence reconstruction of the background, according to campaign to establish adaptive background sequence

基于optical flow算法的动态目标捕捉，缺点是背景动态变化较大时算法会失效-Dynamic optical flow algorithm for target acquisition, the disadvantage is the dynamic changes in the larger context algorithm will fail when

光流法提取动态背景前景目标，具有良好的抗噪和抗干扰能力。(Optical flow extraction of dynamic background prospects, with good anti-noise and anti-jamming capability.)
