What is the method to merge foreground object in same background?

I have a video sequence that show a moving car (fix camera position). What method that we can use to show the car motion in one image?

What do you mean by "show the car motion"? Are you referring to optical flow?

Like this picture.

Ah, I see. I think you could try segmenting the moving object in each of desired frames (probably using something like optical flow as a guide) and then superimposing the moving object on the static background image.

If you attach a sample movie file, I may be able to play around with this idea a bit.
