When an object is moving on the surface parallel to the earth surface from the high latitude to the low latitude (from the low latitude to the high latitude), it is affected by the deflective force to west.

当运动物体距地球自转轴的距离发生变化时，运动物体要保持因随地球自转而获得的角动量守恒，就会相对地球发生纬向偏转，好像受到某种力的作用。

After this procession has been done, the background is easily filtered, the edge of moving objects are reserved. There are some things with invariableness color, and only similar color objects in the background. We set a filter template. Others color pixeles are filtered and the image is smoothed for eliminating noise, then the remarkable color region of the image is considered as moving object.

对于一些特殊的物体比如整个目标都是恒定色，而背景中又无这种相近颜色的物体，设置一个模板进行滤波，把该物体的三种颜色相近的像素点留下，其余点滤去，同时再作平滑处理去噪声，则在图像显著的颜色区域即能找出运动物体。
