Foreground-background differentiation in a vehicle

A method for segmenting a first scene from a sequence of scenes is described. In this case, the sequence of scenes was captured by a camera in or on a vehicle such as by smartglasses. The method determines an optical flow of the first scene, on the basis of the sequence of scenes. In addition, the method determines statistical variables of the optical flow in different partial regions of the first scene. Furthermore, the method determines, on the basis of the statistical variables, a separating line between a foreground region and a background region of the first scene. In this case, determining the separating line includes determining, on the basis of the statistical variables, an indicator of whether the optical flow in the background region is attributable to a movement of the vehicle.
