Description: 光流是一种简单实用的图像运动的表达方式[1] ，通常定义为一个图像序列中的图像亮度模式的表观运动，即空间物体表面上的点的运动速度在视觉传感器的成像平面上的表达。这种定义认为光流只表示一种几何变化。1998年Negahdaripour将光流重新定义为动态图像的几何变化和辐射度变化的全面表示[2] 。光流的研究是利用图像序列中的像素强度数据的时域变化和相关性来确定各自像素位置的“运动”，即研究图像灰度在时间上的变化与景象中物体结构及其运动的关系。一般情况下，光流由相机运动、场景中目标运动或两者的共同运动产生的相对运动引起的。光流计算方法大致可分为三类：基于匹配的方法、频域的方法和梯度的方法。-Optical flow expression is a simple and practical image motion [1], is usually defined as the apparent motion of an image sequence image brightness mode, ie velocity of points on the surface of the object on the imaging plane space vision sensor expression. This definition is considered only optical flow shows a geometric variation. 1998 Negahdaripour will redefine optical flow motion picture geometry changes and radiometric variations comprehensive representation [2]. Optical flow study is the use of temporal changes in a sequence of images pixel intensity data and to determine the relevance of each pixel position of " movement" , that is, the relationship between research grayscale image at the time of the scene changes in the structure and motion of objects . In general, the optical flow by the camera motion, relative motion common target movement or motion scenes both produce caused. Optical flow calculation method can be broadly divided into three categories: matching meth
