Patent abstract
A system and a method are disclosed for identifying pixels belonging to moving objects in a series of images by using a signed difference operation. A first signed difference is determined between a first image and a second image. A second signed difference is determined between a second image and a third image. Pixels that change from a positive sign in the first signed difference to a negative sign in the second signed difference belong to the moving object in the second image.
