中文说明：根据运动物体两帧图像，可以得到目标的运动光流图，则可以检测到运动目标，在视频信息中也可以得到，并且对光流信息进行量化，同样可以得到运动目标的轮廓，在动态场景下也可以实现。
English Description：
According to moving objects image we can get the target motion flow image can be detected moving target, in the video information can also be obtained, and quantify the optical flow information, also can get the contour of the moving target. In dynamic scenes can also be achieved.
