Hi, i want to calculate traffic jam. To do this I got the contours of the foreground.. But I have a big problem. If the traffic for a long time.And the cars do not move for several minutes.

As a result, the cars will be part of the background(the cars fade).

How can I solve this problem. Many Thanks.

Can you get a reference image for the empty road?

Yes, I can, but the background will change with time.
